I am interested in setting up a FOWLR
tank. I am still in the research phase and considering different options. I have been reading on the need for water movement. i have read, in a freshwater forum, about under gravel jets. It basically a series of PVC
plumbing buried under the substrate with jets sticking up through the substrate. The water is supplied via a powerhead or the pump from the sump. See link:
I am curious has anyone used these for a SW
tank? Will the help or hurt LS
Thanks for your input. I am learning a lot for everyone here.
