How often do you do a water change Pegasus
About 15-17% every couple of months or so. It's been almost 3 months since my last water change. However, this isn't really possible with a new system, and it's recommended that you change about 5% weekly, 10% every two weeks, or 20% every month. It's easier to change small amounts frequently, than to change large amounts infrequently. At least that's what I hear... lol! Actually, it's better for your system to do small water changes as it doesn't make large changes to parameters. Until your system is mature, which can take a year or two, it needs a good bit of attention.
