So I have never paid attention to the pH in my fishtanks water that being said now that I’m gonna have a very big Cichlid tank I want their colors to be very vibrant one of the things to get this to happen is to have a high pH. I am on city water and my pH is 7.0 There will be a there will be around 500 gallons of water that I need to treat so it needs to be something cost-effective and easy to treat that many gallons. I don’t know if it helps but I will have a sump and plan on running a plant refugium I have purchased the Cichlid sand but don’t know where to go from here. I don’t want to Drop $1000 on fish for them not to reach their full potential.
