Fishyladdy Posted January 7, 2016 Report Share Posted January 7, 2016 Is this stuff ok to use with crystals? I have some with one of my tanks and really like it but wanna know more info from people on it before I take the plunge and replace all my sand with it for the crystals! My phone out of tap is 7.2 Thanks Quote Link to comment Share on other sites More sharing options...
Jaykidding Posted January 7, 2016 Report Share Posted January 7, 2016 Well it's a good substrate, it's buffers and all, BUT as you just mentioned your tap has a ph of 7.2, I assume your using tap, so I wouldn't say its a good substrate for you if your using tap. Or for any buffering substrate. Why? Because if you use tap water as your main water source,the tap will kill the buffering ability in the substrate. So if you want to use any buffering soil or as you mentioned fluval, you may want to purchase a RO unit, unless you are looking to kill the buffering ability so that it would be a neutral soil.

Pokeshrimp Posted January 7, 2016 Report Share Posted January 7, 2016 Yea i agree with Jaykidding. I have fluval stratum but at the time i didn't really know what i was doing and i used tap water and within weeks the substrate no longer buffered.

Fishyladdy Posted January 8, 2016 Author Report Share Posted January 8, 2016 Ok so I do have a filtering system on my water supply does that make a difference? Quote Link to comment Share on other sites More sharing options...
PlantDude Posted January 8, 2016 Report Share Posted January 8, 2016 Ok so I do have a filtering system on my water supply does that make a difference? If you can produce RO water or RO/DI water with your filtering system you'll be good. TDS out of that should be ~0 to get the most out of your fluval substrate.

jem_xxiii Posted January 8, 2016 Report Share Posted January 8, 2016 Also tap water with high ph breaks the substrate down quicker, or so i hear Quote Link to comment Share on other sites More sharing options...
