After realizing my intro thread probably shouldn't contain all the questions it does, I'm going to bring my inquisitions to THIS part of the forum. I'll figure it out...sooner or later I've tossed ideas ranging from another 55gal. with a full custom sump/skimmer to my most current 29gal. HQI Biocube. Bottom line, I don't want/need anything more than a pair of clowns (True Percula) and a BTA, or bubble-tip anenome (btw, the usage of acronyms in the aquarium industry is terribly frustrating). With a little bit more digging, I learned that BTA's are completely comptible with true perculas so I might be better advised to go with a carpet (confirm/deny/indifferent)? I know the standard lighting on the Biocube is not, typically, substantial enough to care for an anenome but I have heard, in some cases that it can be. I still feel better going with the HQI, though. I have also come the realization that 2 small powerheads would be a neccesity. Live sand/live rock are also on my list of must-haves. How do most of you get your water? Purchase or have an RO/DI unit? Regular water changes are a must but purhcasing pre "mixed" ocean water sounds like it can become expensive and making my own fresh water is a foreign concept (hook-up/implementation). I've come across a protein skimmer that fits within the Biocube filtration system--the SR3 I believe. Anyone have any experience with this unit or would recommend it for my intended setup? Anyone recommend an all-inclusive water testing kit? Thermometer? Refractometer? I'm still undecided about the heater. One of my goals is to have a clean looking setup without a lot of clutter. Obviously, the power heads and heating element will combat my goal but I see this only as another hinderance to overcome. I may have left some things out but I'm sure my mind will wander onto those things again. I plan on purchasing everything I need (to get the cycle going) this month. Up to that point, I'm impressionable and still soaking up what I can.
