Hi everybody, before i spend approx. 150.00 ,i would like to get some opinions on the sapphire skimmer for my 24g ap . Tank has been running approx. 5 months ,with 5 gal water changes a week , every thing is running great , but would like to cut back on water changes to every other week. Do you think it is worth the expence. thanks in advance Stuart. p.s. I have a a pretty heavy load in tank with 4 small fish and a bunch of corals soft,lps and 2 sps frags up high in the tank. Tried the fission skimmer (what a piece of crap).
