BTW, this is off topic but do you know much about tube anemones?Sure- the more vibrant the better... also you’ll be able to gauge by looking at what the same coral looks like in other tanks. overall health is easy to tell... fine tuning is an art that comes with experience. I went a solid year and my corals had great color (best I had seen) then I started dosing aminos (note: this isn’t me dose aminos... at least not yet) and realized even more color potential. In other words- as your process refines you’re gonna pull even more color out. If the system is stable and your corals aren’t brown then you’re doing great. Some of the higher end montis will challenge you to bring out their best colors... they won’t look bad but you’ll see a pink ring around the same coral in a buddies tank and want to figure out how to get it on yours case in point.. the jf altered ego.... I have it and it has a nice blue color- certainly doing fine in my tank, but if you look online, it can be so much more. (These are the types of corals i keep on discs and move around to see how they adjust)
