[Finsky]

I forgot to mention I have a plug and play German made Aqua-Medic Turboflotor Multi-1000 protein skimmer hanging off the back of my five foot 120 gallon Reef Tank with 150 lbs or live rock

Each day it typically fractions out one inch of "black" liquid into the collection cup. I empty the collection cup everyday if possible to keep the efficiency at the highest level.

This skimmer is rated for up to a 250 gallon tank.

I also have two Rena XP4 Canister filters with the top basket of their four baskets fillled with four 10 oz bags of Chemi-Pure and a bag of six tablespoons of Doctors Foster and Smith Phospure.

These are each rated for up to a 265 gallon tank.

I do not know how much vitamins and essential elements these filters remove.
