It’s funny how much less algae there seems to be at the higher ratio. I’ve experienced the same.
Yeah, and I took it extremely slow to get down there. At one point it was like I had this weird mini cycle. I saw the overflow teeth all turn brown and a buildup of algae all over the rocks. Now that I’m back up over 50:1 the tank looks way better and so do the corals. A lot of people don’t believe in ratios, but from what I’ve seen from being at both extremes is that it appears to be important not only for algae control, but also overall stability of the system. The tank really got dirty at lower levels of NO3 and the lingering Dino’s become more dominant on the rocks. Also, somewhere along the way down to 14:1, the low NO3 also triggered a spionid worm outbreak. Now that the NO3 is back up they seem to be thinning out again.
