Temp dropped to 65!!! WOW, that's a little cold for sure. Hope everything is ok

Everything is fine, thanks for asking. The E. yaeyamaensis (frogspawn?) is getting bleached but that's because it's right under the MH. I know that has nothing to do with the temperature but I felt like sharing.

How high up is your Vortech? What I noticed a little while back is that if my powerhead is a tad too high that it will occassionally cause a vortex and slurp some air into the powerheads intake. The powerheads then dices the bubble and generate microbubbles. It happens so fast that unless you are standing there for a long long time watching and waiting for it you won't notice it.

It's actually really low. It's in the exact centre on the back panel (48x21) and it's under the overflow box. I'm not even sure they are bubbles. They could even by tiny little bits of dust from the sand bed. Every so often the pump blasts and moves the sand a little. It's on Reef Crest mode I think, and that's random. It's no problem. I don't spend much time looking at the tank anymore, anyway. After the build, the rest is boring now. But I do like my anemone.
