I don't know the exact 100% sure fire answer to this question. This is what I can tell you, I ran a 90 gallon tank for 10 years with no sump, only using 2 H.O.T Magnum filters. One ran with Carbon the other only the Micron filter. I did a 50% water change every 6 months. The tank had a dozen SPS corals the grew regularly and need trimming. I had a Pygmy angel,flame angel and a powder blue in there for the 10 years as well. Feeding was every other day for the fish and nothing was ever dosed into the tank. The lighting was a 150W MH and 2 actinic bulbs. I also had 2 Maxi Jet 1000's for flow. Never had a problem once, never lost a coral or fish in that system and ran no skimmer either. My tank today is much different and most of those corals are now in this tank. I have noticed a difference in some of the corals, some good some bad. So I don't think there is a 100% sure answer. But steps forward are needed, especially when talking about breeding fish, instead of capturing wild ones.
