polgara Posted January 13, 2005 Report Share Posted January 13, 2005 Has anyone ever used pumice in there tanks. I was thinking of sticking a whole lot of peices together and putting them in my tank. But I want to make sure that it is safe first. Quote Link to comment Share on other sites More sharing options...
Caryl Posted January 13, 2005 Report Share Posted January 13, 2005 How are you going to stop it floating? Quote Link to comment Share on other sites More sharing options...
Staplez Posted January 14, 2005 Report Share Posted January 14, 2005 Good question. I haven't thought about doing it but is does make me you think if there is a chemical risk. Years ago I used to be right into collecting and studying rock and minerals. I was a member in a club blah blah blah, anyway. Something that came up more then once in club meetings and rock and mineral sales was some rocks and minerals can release chemicles into the water. And some of them can be very nasty. Be careful what stones you put into the tank if you are unsure. Quote Link to comment Share on other sites More sharing options...
Staplez Posted January 14, 2005 Report Share Posted January 14, 2005 you can quickly make pumice sinkable if you have a pressure chamber Quote Link to comment Share on other sites More sharing options...
Alan Posted January 14, 2005 Report Share Posted January 14, 2005 Yeah Staplez, I'm sure everyone has one of them handy. While I was typing that, I just realized I HAVE got one. My pressure cooker You smart ass Alan. Alan 104 Quote Link to comment Share on other sites More sharing options...
suphew Posted January 14, 2005 Report Share Posted January 14, 2005 Pumice itself is okay, there are people that use it in their filters because of the high suface area, the problem with using large pieces is that when it forms it collects other rocks etc that might not be safe. There are a couple of simple tests people do to test rocks, the first is to put vinager on it to see if it bubbles (which isn't much use to you), the second is to test some water (for PH, Kh, etc) then put the rock in for a couple of weeks and then test the water again.

Staplez Posted January 14, 2005 Report Share Posted January 14, 2005 yeah that might work But pumice could have sufuric acid in it then again if it's been drifting around for some time it could be all gone. You could try keeping it in water over a some time then test the pH of the water. I think it would look rather nice in the bottom of a tank. If you can get it to stay there. Good luck making it sink.
