Well I guess if you have a SPS tank with major waterflow they probably wouldn't even be noticable. In my Sump/Refugium (20g 2/3 full) where there is a 30-40x turn over rate, there are very few Flattys in there, unoticable unless you look for them. I have never syphoned even 1 single Flatty out of there. But with a Softie/LPS tank where you can't run that kind of turn over rate, you have to syphon them out don't you? Would you recomend that I stop syhoning them all together and see what happens?
I also believe they are good for the tank... it's just there are too darn many :P .
