I'll never run a tank without a skimmer, as a matter of fact, I recently purchased a aqua-c skimmer HOB
, and it pulls more junk out of the water in two days than My in-sump did in 5 months.
an excerpt from Fenners new book states this-
Protien skimming is pivotal for many Aquarium systems.
Even though one does naot absolutly need a protien skimmerto have a succesful marine aquarium,Most folks will discover that it is categoricallythe most effective and reliable means of nutrient export (especialy for begginners)
He also seems to consider it a natural filter, that is considering the amount of sea foam washed ashore.
He, and I strongly encourage the use of a "Good" skimmer.
