IMO it just doesn't make sense to me to have high flow in a troph tank. When I did SPS in a reef it did to remove debris, circulate food and reduce algae. But in a troph tank, I like it when the crap settles because I am just going to siphon it in a weekly water change (40%). I have no flow other than a sponge filter bubble stream and a hang on filter with carbon.
I see the most hard core Troph keepers/breeders running spong filters only. So I just follow that success. Flow cannot be that important to a troph.
this is what i have noticed too, and i have as well been following this method with success, I have two sponges per 120g tank, each rated for 125 gallons, running off a very strong whisper 100 - there is plenty of surface agitation for O2
