Im working on a design for a new tank for my little RES, Jackson. I love Saltwater aquariums and have fallen in love with the idea of a Sump. The only thing is that I am having trouble with the media.
My current thinking is thus:
1. Mechanical filtration on drain tubes
2. Anachiris or another freshwater plant to act as a nitrate remover <refugium>
3. Sand for more biomass<refugium>
4. Carbon(This I am unsure of)
All of this would be kept in underneath the Display tank along with heaters and plumbing.
Is there anyone out there who is using a sump for the their turtle and can give me some advice?
