And fortunately, @Battlecorals impressed upon me the importance of daily alk tests. My calc rx feed clogged, alk dropped from 7.7 to 6.7 in a day. Bumped it back with some 2 part to 7.5 this morning after fiddling late last night.
Siphoned out the sand bed last night and blew out the rock work. Made a big difference. Sand really white again, I just need to get that into a monthly routine.
So today I re-learned the lesson of not going by your eyes to set your light intensity. I have 4 photon v2s about 15" off the surface, and had them set about 40% at peak. I have had a seneye par meter but with the business of life hadn't really gotten to check the tank. Turns out I was only getting about 90ish par at the surface and 70-80 at the bottom.
It's really bad when you know better and you still do it wrong
Today I vacuumed out parts of the sand bed. Had my supermale solarensis jump out on to my tile but I was able to pick him up and put him back in within about 40 seconds. Fortunately none the worse for wear.
I thought I had lost a royal flasher wrasse but he came out to eat live blackworms today. He looks a little thin but he ate like a pig and his colors are still bright, no idea why he vanished for 3 + weeks.
