Agreed that macroalgae will make bubbles. Just never had so many before in any of our past reefs with about as much lighting and MA. Most of the MA is growing from large rocks so they can't really be put into a HOB. Actually, don't think I can hang anything on the back of that tank due to the Eurobracing
Was wondering if any of the DIY-selfers had any bubble-trap ideas? Am using Hagen 802s with a modified (smaller) prefilter.
