Mr. Goemans:

I've been reading your articles regarding plenum systems in FAMA for several years now and set up my first reef system almost 10 years ago following your advise (and I have to say its been quite successful!).

I'm in the process of setting up a FOWLR system with a display tank of 125 gallons and a 55 gallon tank underneath as a remote plenum. I believe I read in a recent issue of FAMA where you stated that you now believed a larger sand grand size of 2- 5 mm would be better than the standard special grade reef sand (CaribSea). Would the CaribSea crushed coral be a good size then? If so, that would be nice since its about 1/3 less expensive as their special grade reef sand. I assume the same depth of 4 inches would apply.

Thanks in advance for any advice you might give me regarding this question and especially thanks for your contributions to the hobby!

Hi Joe,

Thanks for your email and the crushed coral is a perfect substrate for plenums systems. And yes, the depth stays at four inches.
