How important are protein skimmers?
Question: Everyone tells me I must have one for my brothers saltwater tank, 29 gallons. We do, but I am unable to work pretty well. This is the bio-cube 29 skimmer, with a wood block attached to the air pump tubing.
Answer: skimmers are not necessary, but you have a sine qua non a way to remove the bad proteins in water. There are several ways to do it, but a protein skimmer is the easiest. Doing water changes is usually the objective is not sufficient if you have corals.
