I came home to find my 10gl. growout tank w/a slow leak , the only other tank I had was a 20 w/ some frogs and newts in it. that tank was filled w/water halfway,and been running for years...i pulled everyone/everything out , did a quick rinse, and placed everything from the leaky 10 into it. the 20 is now topped off and i'm wondering if i'm gonna have "new tank syndrome" since it is now full. the young fish I have in there now are sensitive to nitrates/ites, and ammonia spikes. does anyone think I'll have any of these within the coming days?
