Hi I currently have 200 litre 4foot tank with a white crushed coral type substrate and I'm wanting to change it to sand in an effort to permanently lower the ph from 8+ closer to 7 and also because I like sand look how do I do this without altering the ph too suddenly and stressing the fish
thankyou
