thanks for the info. the problem with someone coming over is that the only people that could do it are kids, and well i really dont want some kid "trying" to take care of my tank cause i really cant trust them to do it right or to actually do it. i went to the pet store today and saw that they had feeder pyramids for saltwater, would this be ok or not. ok, for some tank details, i have a 24 gallon nano cube, with about 30-40 lbs of live rock and 20 lbs of live sand.
