I have recently added African Cichlid Mix (Carib Sea) substrate to my 125 gallon aquarium. It keeps the ph constent and does all that fun stuff. However I am guessing i still need to add salt after every water change. I am going to purchase Cichlid Lake Salt. Unless you all talk me out of it or tell me not to buy.I hope that i am doing the right thing and not wasting my money on unneed materials.
