The Clarity units come in two sizes. Our pond is 6K gallons and we needed the larger unit.
The unit consists of a trickle tower & a foam fractionator. The TT reduces nitrates while the FF reduces DOCs.
So, conceivably, even if there aren't enough DOCs to foam like crazy the TT will still be kicking butt on the nitrates.
And since it's being added to an existing circuit (no-niche skimmer, 1/4 hp Artesian PP pump, Ultima II 6K filter), there won't be an additional pump to purchase or more electricity required to run it.
