Stop using chaeto use seagrass.. Chaeto is now obsolete... Like bio balls.. Throw some seagrass on top of your chaeto and watch it out grow it.. Only the strong survive,,,lol.. Nutrients need to go fast, or your just keeping chaeto for aesthetic reasons... It grows to slow I repeat it grows to slow... What you want in your tank is something that will grow fast and get those bad nutrients out fast... Or you could just stick to water changes and no fuge...
Thank you, this is a public service annoucement... Check out Bob 1000's The best thread... For more info pm me for order details,,,lmao.. But it's all true...
