I am cycling a 20 gal standard tank in anticipation of getting some shell dwellers. I am trying to raise the pH from 7.4 to mid-higher 8. A large net of crushed coral has not budged the 7.4 in 2 weeks of trying.
Any suggestions would be be appreciated.
Fighting with your tap water chemically is a tiresome thing. If you increase your pH in two weeks, what will hapen when you do weekly water changes?
Captive bred shell dwellers may be already accustomed to lower pH levels. Check with your source. I keep all kinds of Tanganyikans in my Michigan tap water that is more or less like yours.
7.4 is on the lower end for shellies, but most captive bred species should do fine. It depends on what species of shell dweller you want, and if you want to breed them. Breeding them might be tricky in that pH, but just keeping them shouldn’t have any issues.
