Skimmer Nog color!
 

40 gallon tank 60 or so pounds of live rock, live sand lots of corals next to no algae, hi Nitrates, tank running about a year..Bio load was five clowns none bigger than 1.5" couple brittle stars, couple cleaner shrimp and feed corals mysis 2 maybe three times a week....So now I put a Tunze 9002 skimmer in the tank I know under sized but I don't want SPS quality water with the corals I have. Skimmer running about 2 weeks and the waste it produces has a light green tinge rather brown...Never had a skimmer before and never read much about green skimate Does this mean anything? do I need to adjust something..? lol not much to adjust really..Just wondering why it is green..

That skimmer skims really wet/diluted. I have the same issue. I've never got mine to skim drier/darker.

I'm guessing this equals a less efficient job when it's only green?....I guess better than nothing but a bit pricey for a half arse job...

should shoot for a black color and thick.

Not really less efficient. It's just pulling more water along with the skimmate.

How do I do that, less air?

adjust the height of the skimmer in relation to your water level. Bring it up a little higher probably a few centimeters. just play around with the height of your skimmer for a few days till you get your desired output.

Moved up about 1/2" Not perfectly level now because of thick trim on the tank but will see what happens, thanks.
