The word, "Optimus" in Latin translates to "the best".
NT Labs Optimus is a concentrated aquarium water dechlorinator & conditioner, it detoxifies ammonia, nitrite, nitrate, & heavy metals.
Optimus is a highly concentrated dechlorinator and conditioner that makes tap water safe for fish. Optimus removes chlorine, chloramine, halogens, and detoxifies heavy metals found in tap water.
Optimus detoxifies ammonia, nitrite, and nitrate into a safe form that can be removed by the biofilter. Always test your aquarium water using NT Labs Test Kits.
Optimus should be used when setting up a new aquarium and during every water change.
Optimus should be used alongside Satus when starting up or ‘cycling’ a new aquarium to control ammonia and nitrite levels, thereby preventing ‘new tank syndrome’. Optimus is buffered and will not negatively affect pH or skimmers.
How to use:
- One bottle cap is approximately 5ml. Each scale on the bottle cap is approximately 1ml.
- Add 5ml to every 200 liters of freshwater.
- Shake bottle thoroughly before use.
- When adding to a new aquarium, calculate aquarium volume litres (length x width x depth (in cm)/1000).
- See label for full dose rate
- Dose for the full aquarium volume and add directly to the aquarium.
- During a water change, add the appropriate dose directly to the new water before adding to the aquarium.
- A half dose should be used when water temperature is +30°C and chlorine and ammonia levels are low. The normal dose can be doubled for water containing exceptionally high chloramine. Optimus can be used up to 5 times normal dosage to detoxify nitrite in an emergency.

The Best Coffee Beans in the World for the Price
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
First of all, my headline is an opinion. I understand that coffee is beloved by most of humanity and that it engenders strong opinions, so don't be offended if you disagree. Let me state my case and build some background and context:
1. I drink coffee black. If folks are putting cream and sugar into their coffee, or making espresso drinks with milk like lattes or Cappuccinos, I feel as though they don't have to worry quite as much about things like acidity/bitterness in coffee because milk changes the taste a lot. If you also drink coffee black, this review is perfect for you.
2.. This review is meant for people who intend to brew these coffee beans with a classic Drip Coffee Maker or a French Press. This is because these are the only methods I've used to brew the coffee. While these beans from Lavazza are called "Espresso Roast Coffee", that does not mean they can only be used for Espresso. If a coffee roaster labels something an "Espresso Roast", it simply means that roaster believes the beans would do well when prepared as an Espresso. That does not mean it can't also be used via other preparation methods. There is a little picture/symbol on the front of the package that indicates this is also good when prepared as Drip Coffee or via French Press.
2. While this particular "Espresso Roast" is not the only type of coffee beans from Lavazza that can be used for drip coffee, I would recommend sticking to varieties that are labeled "100% arabica." There are two types of coffee beans: Arabica and Robusta. Like anything else, you could Google this and find 2 full pages of info to read regarding the differences between these two bean types. But the easiest breakdown seems to be that Robusta beans are more intense (or robust, guess it's in the name) but often more bitter. The bitterness especially becomes present when the coffee is slowly brewed as drip coffee. This is why Lavazza has lots of varieties so you would need to use their website to determine the full list of products they sell that are 100% arabica. You will see that they only have the icon indicating the coffee is good to be prepared as drip coffee for their 100% arabica blends, going along with what I'm saying.
3. Going back to point 2, this is what makes Lavazza Whole Bean Espresso Roast so amazing. There is simply no bitterness regardless of how strong you make it. When you look at Lavazza's description of tasting notes for this blend, they mention Floral and fruity notes. This is where I always feel dumb as I don't personally get those notes. For me it's extremely rich, full bodied, and I get those nice chocolatey, roasty notes. I don't mean like dark chocolate or deeply roasted notes like I would get from a dark roast, because you can clearly tell it's a medium roast. More of a milk chocolate type of flavor profile. I definitely don't get the fruity/floral notes Lavazza mentions, which for me is good as those are not my preferred flavors. I'm not saying that those listed flavor notes are purely just subjective or matter of opinion, but I taste what I taste.
At the end of the day, in my mind what makes the coffee quality is that even when you brew it much stronger than what you might say is average, there's simply no acidity or bitterness. If you purchase the 2.2 pound bag and drink this coffee for a month straight (or however long the bag lasts) and then go back to major American brands, like ones with initials like SB or DD, the acidity and bitterness will become obvious immediately.
4. Regarding point 3, am I saying there are no American Coffee Brands or American Coffee Roasters that make good coffee that isn't bitter and acidic? No I'm not. What I'm saying is that those will be boutique coffee roasters or smaller brands that will be much more expensive than this Lavazza Coffee. Are there any big American Coffee Brands that make coffee like Lavazza? I'm saying NO. Flat out, unequivocally, no. Lavazza is a billion dollar Italian brand. I love to support local companies when possible, but they are not going to be price competitive with Lavazza. So as your everyday coffee, if price is important to you like it is to most, then obviously it's all about finding the best for the cheapest. Queue this coffee.
5. This coffee should run you no more than $18 full price for 2.2 pounds as of December 2024. You may occasionally see it priced higher, this means it's sold out through Lavazza directly and a third party seller has jacked up the price. I would not purchase the coffee from any other seller than Lavazza so watch out for that. Just as importantly, YOU DO NOT have to pay $18 every time if you watch for sales. There are frequent sales of anywhere from $2-$5. So you can get this for as cheap as $13 which is an absolute steal for 2.2 pounds of this glorious coffee. It's still a great deal at $18 for the quality, but at $13 or $14 it's the ultimate no brainer. Maybe order 2 bags when it's on sale.
6. You don't get to control how fresh the beans are when you receive them which sucks. But to Lavazza's credit, they often arrive within 6 weeks of the packaging date. This is also to their credit: They have the date the beans were packaged on the side, not just the expiration date. The key thing to know is that there is indeed a big difference if you are drinking 4-6 week old beans (never got them fresher than that) vs 3 or 4 month old beans. The difference in freshness is pronounced both in the taste and even more so the smell. This is just the reality of ordering this coffee at this amazing price, have to trust you will get it relatively fresh. For my experience, I have for the most part.
Bottom Line: If you are an American like me mostly making and drinking drip coffee, and maybe not as sophisticated as an Espresso drinker, drinking this Lavazza coffee will make you realize that other brands you have been consuming are acidic and bitter when brewed as drip coffee. You will probably either place this on Autoship if that's your kind of thing, or at the very least you will order it again. But I guess you will have to take the chance on it to find out. I don't think $18 (at most) is that big a risk.

Smooth, Rich Coffee That Makes Every Morning Better
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
I have tried so many coffee brands over the years but Lavazza Espresso Whole Bean Coffee has really become one of my favorites. The instant I opened the bag, the smell was wonderful. It smelled like rich, fresh coffee, and my kitchen instantly turned into a cozy little café.
The smoothness and balance of flavor is what I like about this coffee. Some espresso coffees can be too bitter or strong but this one has a very nice medium roast taste that is rich without being overbearing. It tastes slightly sweet and creamy, so it is good both as regular coffee and in espresso drinks.
I run these beans through my espresso machine every morning and they grind beautifully. The crema is thick and a beautiful golden color, which makes my homemade lattes and cappuccinos all the more special. Even my husband who is very particular about coffee said how fresh and flavorful it is.
The 2.2-pound bag is also a great value, as it lasts a long time, even in a house full of coffee drinkers. I like that the beans stay fresh when sealed properly and I have not had any oily/stale beans in the bag.
I also like that this coffee gives you a nice energy boost and doesn't taste harsh or acidic. It's smooth enough that I can drink more than one cup without it upsetting my stomach.
Overall, I think Lavazza Espresso Whole Bean Coffee is a great choice for anyone who loves strong, smooth coffee with a high-end cafe taste at home. I will definitely keep buying this for my daily coffee habit.

Solid coffee, good intro to Lavazza
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
I've used this and it's genuinely good coffee. The 100% Arabica beans produce a smooth, clean cup with a nice aroma and solid crema. No bitterness, easy to drink and works well in both espresso and drip.
That said, if you're deciding between this and the Lavazza Barista Gran Crema or Qualita Oro, I'd go with those every time. The flavor is richer, the crema is thicker and the overall experience is just a step above. This one is still a solid 4.5 in my book, rounding up to 5, but the Gran Crema and Oro are my personal go to.
If you're new to Lavazza this is a great starting point. You won't be disappointed.

⭐️⭐️⭐️⭐️ Great Coffee, but Price Fluctuates a Lot
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
The Lavazza Espresso whole bean coffee is very good quality. The medium roast is smooth, balanced, and works well for espresso, lattes, and cappuccinos. Beans grind evenly and produce a nice crema.
My only issue is the price instability. Sometimes it’s around $17, which is an excellent value, but other times it jumps to $26, which feels high for the same product. Because of this, it’s best to watch the price and buy when it drops.
Overall, great coffee with consistent flavor — just keep an eye on pricing before purchasing.

My everyday espresso bean — fresh-ground changes everything
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
I've gone through more bags of this than I can count — it's become my default espresso bean and I don't see that changing.
I grind it fresh for espresso and the difference vs. pre-ground is immediately noticeable — more crema, better aroma, cleaner taste. If you're still buying pre-ground, this is a good reason to stop.
Flavor-wise it's smooth and approachable — medium roast means no harsh bitterness, no aggressive dark-roast smokiness. Just clean, well-balanced espresso. The 100% Arabica shows; it doesn't have that robusta edginess you get in cheaper blends.
The 2.2lb bag is good value compared to buying smaller bags or anything from a specialty roaster. For everyday home espresso, the price-to-quality ratio is hard to beat.
Only mild gripe: the bag isn't the most resealable after the first open — I transfer mine to an airtight container. Minor inconvenience for a bean this good.
