So my turtle is a baby and I got a new tank from a friend pretty big one not sure how many gallons. In order for the filter to work properly it needs to be a certain level. The filter is a aqua tech 30-60. This goes way beyond the line I have set for him on the rock he has. I was thinking of making a PVC makeshift one higher in order for the filter to work. I have heard that the higher level of water can kill my turtle. Anyone know what should I do?
