cracker Posted December 2, 2005 Author Report Share Posted December 2, 2005 If you want things for them to hide in you could just use regular rocks, works just fine for FW. I've been thinking it would be interesting to set up a marine tank that looks like a FW tank, driftwood and stuff... The calcereous rock assists gretaly with Ph though...may be an issue.

lduncan Posted December 2, 2005 Report Share Posted December 2, 2005 Alkalinity is the pH stabiliser, not rock or sand. Layton Quote Link to comment Share on other sites More sharing options...
wasp Posted December 2, 2005 Report Share Posted December 2, 2005 My QT works like this - It is a large plastic tub that used to hold a fishing net. ( Commercial snapper one ). There is a cannister with that eheim glass media that is excellent base for bacteria but don't adsorb copper. In the tub is a bunch of garden variety rocks, dunno what they are but they not calcerous. The cycle in the cannister has completed & there is currently 3 medium sized fish in the QT, no nitrite buildup. Surprisingly little nitrate buildup also, but when it happens I'll do a massive WC. Rocks provide ample hiding the fish are not overly stressed. If PH gets a little low i dump a bit of kalkawasser in manually. I think this is an easy way to do it because there is very little work to it & it provides a relatively stress free environement to the fish. When there are no fish in it I'll turn everything off bar the cannister, and I'll throw the odd pinch of fish food in to keep the biological filter activated. BTW if anyone local needs anything QT'ed / copper treated, welcome to put it in mine for a while. Quote Link to comment Share on other sites More sharing options...
