I have been putting together an 8 gal biocube for my brother for Christmas, and we are going to move it over to his place on Monday. We have been doing 1 gallon water changes every week to 10 days and the parameters have stayed pretty stable. We bought him a test kit and I think he will be able to maintain the system easily. My question is this: does anyone have and words of advice I should send along with him? I worked to make the system as self-sustainable as possible (added a hydor-flo, replaced bio-balls with LR rubble and chaeto, 8.5 lbs liverock). I threw in some mushrooms. zoas, and a piece of colt coral since they are real easy to keep. Right now there are 3 sexy shrimp and a harlequin in the tank, plus 2 scarlet hermits and 5 mini nassarius snails, a cerith snail or two and a small turbo. I also bought him a GC to RCA to sustain his first splurge into the hobby. Anyone have some general pointers for a newbie? Any fish suggestions? Any other modifications proven successful on a biocube? Anyone dose anything special in their nanos?
