Hello everyone!
I've been looking at your aquariums and I want to switch from freshwater to saltwater.
I have two 720-liter aquariums. I have a few amateur questions.
1. Is it possible to operate without a sump, using only a protein skimmer? (The design of the stand doesn't allow for it.)
2. Is it possible to replace the sump with an external filter like in freshwater?
3. I have three FX5 filters - will they be useful or should I sell them?
4. Can I transfer the coral rubble that is in the sump to the external filter?
Thank you all!
