| Re: Protein Skimmer concept Do not leave the cup full. Empty the cup when it is full. This is material you don't want in the tank.
if you skimmer is new, it's likely pulling out a lot of material, and causing the light yellow water, rather than something darker.
If this doesn't settle down after a few days, or the skimmer has been in use awhile, then you will need to adjust your skimmer to produce a dryer foam. |
