which other rock would work? i need to increasr ph and water hardness, thats why I was thinking of these. Im just going to put 7-8 of them in center with fake plants, no caves or anything like that for peacock cichlids all male.
Unless your pH is VERY low limestone rock is not likely to impact your pH. It does not dissolve fast enough.
What is the test result for KH? If you have a very low pH and KH some crushed coral in the filter would be your best bet. The water being forced through the crushed coral dissolves it a tiny little bit faster than using limestone rocks as your decor.
what about pool filter sand, everybody swears by it and says its rounded, I read that its edges are sharp and that is how it filters out debris in the pool filter, and they change it out when it gets round. can you explain, I have pictus catfish, and if its sharp it would injure them, tia
no the pictus are going into another tank, so the pool filter sand is not good then, due to it being sharp correct? im cofused, if not round sharp right? then why is everbody using it, they dont relly know if its hurting the fish then correct? please explain.
