Great input this weekend, thanks everyone!
Nitrates....let's not forget that the sandbed, an integral part of most systems, will harbor nitrates, too. Some nitrates in any system are to be expected. (Note the "some")
Methinks I'll be sticking with the canister, as have no space or inclination to be drilling anything for a sump or refugium system at this point. Am quite used to cleaning out the "gunk", and will continue to do so.
As far as bio-load goes, I'm not planning to add any fish for quite a while yet (nervous nellie?). What I like? I hope to stick with peaceable sorts. My thoughts....Green chromis... how about a school of 3-4? Love a pair of clowns. Love a bangaii cardinal or pyjama fish (or both?). Anyone have a suggestion about an entertaining and peaceful goby or blenny?
My bottom line....hope to not set up an aquarium where the residents are eating each other!!
One more thing. I'll need a cleaning crew, right? Need help!!
You guys are wonderful, thanks!
