ok so iv recently moved into city limits and so this will be the first time i will be setting up my 125g with city water instead of well water. iv never had a tank this big when iv had city water so wanted to know how those of you with city water dechlorinated and buffered your water? do you hold water in big container (like a trash can) and add chemicals then pump it into tank or do you just add the dechlorinator to tank and then add water straight from tap? also what do those of you who have amazonian fish use to keep the water at the lower pH that these fish need (looking to keep it around 6.5 will have to go test it to see what it is straight from tap here)
