@@lunarminx its working great i recently used it to build a paladarium which if you ever do make sure you cover the front with mesh so the fish cant swim through the holes & get stuck i messed up & lost 2 neon tetras & my mangrove monitor crawled between the pieces of matala & git stuck so i had to pull him out & redo it so he cant do that again
i cannot see this being good at holding bacteria, stone medias orr sinted glass medias are best like lava rock or biohome, only very lazy bacteria will stick to static plastic material no matter the surface area. Also i think that they are not going to catch as much dirt as a traditioonal foam,even the finest one still had soome larger holes, they probably take a long time to clog because they are not collecting much.
You have no clue what your talking about! Ive used this product fpr yrs and know many japanese koi sellers and breeders, in Japan, that also use this product! Until ypu have experience with it... Dont knock it! To clean, i rinse with hose 1x/yr. Always crystal clear water! Lmao!
