Hi there! I'm setting up my nano reef and I thought I could get some help from you guys. Just got an Interpet Fishpod 120. I know it's for freshwater, but I thought I could modify it to suit my needs. Ideally, I'd like to have some soft and hard corals, 3-4 small fishes and the necessary clean up crew. I'm about to order the following stuff: base rock and some live rock Carib Sea Special Grade sand API Saltwater & Reef test kits (pH, kH, Nitrite, Nitrate, Ammonia, Calcium and Phosphate) 2 Hydor Nano 1600 1 external canister filter sea salt Seachem Purigen Fluval Carbon Please bear in mind I want to keep it as simple as possible. I know that the rock and the sand is the biological filter of the aquarium. So I thought that an external filter with poly filter, Seachem Purigen and Fluval Carbon could provide the mechanical and chemical filtration. I have a lot of questions, but here are the most important. 1) Do I have to clean, cook or bathe the dry rock in muriatic acid before I place it in my tank? 2) I'm planning to get rid of the canopy but I don't know what kind of lights I should buy. A friend of mine gave me 3 sets of Arcadia T5 leads sometime ago and I was thinking I could fit 3-4 Arcadia LED T5 tubes. I suppose I'll also need a controller. Or I could buy a decent LED light and forget the diy work. I don't want to break the bank though. What's my options? 3) Do I have to buy a RO/DI filter? I mean, the tank is only 154 lt. Wouldn't it be less of a hassle if I just get the RO water from the lfs? 4) Is there anything else I should buy? Please bear in mind that I want to keep it simple. Thank you for bearing with me.
