I have a 29 gallon saltwater reef/fish set up with an Aqueon 50 HOB
filter and one power head.there is appx 30 lbs of live rock. I have read mixed reviews on changing the filter media in the filter as well as not to use any at all.
Any advice on which way is best. Oh and if I could make this a 2 part question. To siphon ir not ti siphon? I have maybe 2 inches of sand which I dont know if I should siphon or not.
Thanks in advance. My experience is less than 4 months. I would hate for my errors to mean the demise of a fish or coral.
