- UV makes the biopellets much less effective. Not recommended to run them together.
- Daily small WC is a waste of salt. Larger weekly or bi-weekly WC are much more effective.
- Don't skimp on a skimmer - if you want to save a few bucks find a used one rather than buying a cheaper one. If you're willing to put out the bucks for a Vertex Alpha, then just buy a Bubble King.

- Return flow should be 3-6x the total system volume. I like to be right around the 5-6x mark. If you're teeing off for reactors and such you'll need a bigger return obviously.
- An Achilles Tang will not be comfortable in a 180-gallon forever. Ask Marie.

A 40-gallon tank is too small for a QT for it.
- Instead of spray bars I'd just use nozzles. Spray bars cut the flow down too much and take up too much space. Put the CL holes in the bottom pane, not the back, and point the nozzles towards the surface.
