This is a pretty good pricing that I’ve ever seen on Amazon to be honest because everything so overpriced now I’m gonna give my pros and cons about this product and honestly, there’s a lot of better pros than cons for the pros. I noticed that this is pretty good in packaging. Technically, I don’t like the blue packaging on there, but we can leave that for the cons. I separated the bio balls in the blue packaging so or the blue packet or whatever the hell you wanna call it and put it into my hang on the back filter for the quantity you get at least one for the money you wanna buy for personally I love this product this product was pretty good in my tank definitely I still need to get more bio media but not from this company cause girl no shade. This company is all right. OK another pro is this does clear out. Your ammonia is better than chemical filtration. just gotta say I use this product a lot and it’s a pretty good product for the cons again the blue packaging. gotta go change it to something like other than blue because and then the extra material on the blue packet in the code of bio balls. I’m like I gotta just cut this off like what the hell another thing is is that there’s nothing really else to give about cons because it’s not a chemical filtration product so I can’t really judge the hell out of this product so you know ## Frequently Bought Together - Aquaclear Fish A1373 70-Gallon Biomax,White,Large Breeds - Aqua Clear AquaClear Activated Carbon Filter Inserts, 3 Pack – Replacement Chemical Filter Media for 50 Gallon Tank - AquaClear 50 Foam Filter Inserts, Aquarium Filter Replacement Media, 3 Count (Pack of 1), A1394 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/6531594-aquaclear-fish-a1373-70-gallon-biomax-white-large-breeds](https://www.desertcart.gr/products/6531594-aquaclear-fish-a1373-70-gallon-biomax-white-large-breeds) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
