well... there are many many many options available just because just about every fish equip manf. knows that every salt tank owner needs to get one. So everyone is out there to have the best pictures on the box etc.
Take some advice from me, someone who started off on the WRONG track.
Although Seaclone Protein skimmers are cheap and actually do work, they take far too much time to get right, and then the foam production can sometimes take some time to start up. So its a little frustrating getting it all started.
You will want to invest in a good skimmer. You can actually build a nice skimmer, it may not look as fancy as a model off the store shelves, but believe me afterwords your wallet will still be looking fancy
OK, so assuming you dont want to do the research online finding out how to make one. ASM is the new good skimmer... I am actually expecting one in soon. However... the shipping is taking forever.... (of course not really the skimmers fault). But its a knock off of the Euro Reef models (the company split into two, and ASM was born)
Well there you have it.
Actually one question to wonder - what is your bio load like?
Of course a really heavy bio load would want to have something a bigger than what it is rated for. I bought the ASM G2 for a 75
gal tank.
Well goodluck on your seemingly endless journey to find a nice skimmer.
