Hey everyone. I set up a second tank a month ago to treat ich, but unfortunately I have no top and this happened.
If anybody knows how I can stop it, it would be much appreciated. Thanks!
you don't really want a top on a saltwater or reef tank, anyways, it can reduce gas exchange which can lower ph and dissolved oxygen content. i agree go get a powerhead for the DT and QT, you will be happy with the results.
