hey just got done test alk in my 30 which actually is pretty high at 5.37 and is suppose to be 2.9 according to sailfert test i used so is this going to hurt anything i have fish and leather toadstools in the tank and the reason i have started test for everything besides the basics is i would like to start adding additional corals in the future so is the alk a problem and if so how to change it ?
