It's funny you say that...i havn't done a water change yet, it's been 2 months...my lvls are safe...but then again all i have is 2 fish, snail, hermit and brittle starfish....but the water evaps so quickly that when I add water, i'm adding 1-2 gallons...which is equivalant to a 10% on a 30 gal i believe....risky, ironic or have you heard this before?
