Growing Chaeto

[staceyd72]

I have Chaetomorpha and Caulerpa in high flow, this part of my sump has 34x's turnover via powerheads. It's not growing overly fast, then again my NO3 and PO4 read zero on the test kits.

Here is a thread on RC where Anthony Calfo speaks on, in his opinion, the proper way to set up the refugium with the amount of flow and light.
