Hi MF, I have multiple tanks set up under 1 filtration system (wet/dry) to minimize maintenance & to give me more options to keep several livestock, that wouldn't be able to be housed together but can now be viewed side by side............So my question is do I treat these tanks seperately (iodine, calcium, reef blend etc) or can I expect to treat my one tank, assuming all tanks are sharing one water source. I have a 29 (FOWLR) & 15 (Reef) & I have a 10 that I havent setup, but wanted to use as a refugium, I know they are normally kept below, or as hang ons but is there anyway you can have it setup as a display but also as a true beneficial refugium/ Thanks for your comments!
