Expectorating_Aubergine Posted August 5, 2021 Share Posted August 5, 2021 Hello all, I was curious to ask if anyone has put hypertufa into their aquariums. During the lock down I got super bored and decided to make some stuff with hypertufa. Long story short, I made these hollow spheres of varying sizes. I thought they'd be good for fish stuff. I know from plain concrete that it has to cure, and It has. I've had it out in a 55 gal drum since last June. I eventually tossed some guppies in there to see if the water was fine. The guppies have been doing great and having lots of babies. So, anyone ever use this stuff in their tanks? Link to comment Share on other sites More sharing options...
Patrick_G Posted August 5, 2021 Share Posted August 5, 2021 Those look cool! Do they raise the PH? Link to comment Share on other sites More sharing options...
Expectorating_Aubergine Posted August 5, 2021 Author Share Posted August 5, 2021 Well they have concrete in them, so yes. Once they are cured tho they should be fairly inert. Hypertufa has other stuff in it like peat, perlite, gravel and soil. Well, that's what I put in mine anyways.... Link to comment Share on other sites More sharing options...
