Just curious, in marine and reef tanks we use protein skimmers to remove organics out of the water and it stabilizes the water from any nitrite, nitrate, and ammonia from taking place by taking out waste from the water. Question, has anyone ever tried using a skimmer in an aquatic turtle setup? If so what type of skimmer was used? I have been seriously debating on trying to set my turtle system up with a sump system in order to keep my water at perfect conditions for my DBT. Would love some input on this subject if anyone has tried this process.
