Our tank has the two powerheads which move about 550 gph. Even though they are named 20 and 70, they push 150 and 400 gph respectively.

We have monitored phosphates and nitrates and for the last couple of months they have been at zero. We monitor those (and ammonia, nitrites, calcium, oxygen, Ph, salinity) at least once a week. We have an in-line UV filter. We use Phos-ban in our Fluval.

For water we use distilled with suplpliments. We are using Oceanic sea salt.

Feeding is done once every 2 or 3 days and we feed about one quarter cube of the frozen food which is enough to keep them eating for about 30 - 40 seconds.

We use a Sea-clone skimmer which has been very effective at waste removal. Change it once a week.

Our light is a Coralife 4 ft. with four dual bulbs - two white, two blue. It has lunar LEDs not that that matters.

We've considered a refugium but not acted on it yet. IT is a very tempting addition as it would allow us to employ macroalgae without risking it to the fish.
