Need help to determine if a skimmer upgrade is necessary. The DT (mixed reef) is 265g, sump is 65g, fuge is 55g. I am using an ASM G3 and it works great, and is emptied/cleaned every 4-5 days. Water parameters seem to be perfect and water is crystal clear. I know that technically the G3 is too small but how do I know if it is truely too small. Tank has been up for 3+ years with mainly soft corals but I plan to add SPS corals and am trying to plan accordingly. I have been looking to upgrade to something like a SRO5000INT but don't want to make the investment if it is not necessary and won't be of much benefit. Do I go with the philosophy of if it's not broke don't fix it? What should I be looking at to determine if the upgrade is necessary? Any help would be appreciated. Thanks.
