Day 69:
It's been a pretty good couple of weeks with the tank, with a few things going on to keep stuff interesting.
I woke up to my wife in panic mode the other day. She heard the ATO pump go dry, so she dumped a couple gallons into the reservoir. Unfortunately the cheap float-switch ATO that I was using had failed in the on position, so she dumped more in because it immediately ran empty. After doing this three times, for a total of around 6 gallons, she woke me up knowing that something was wrong.
No big deal, as 6 gallons in 200 gallons of total volume won't make much of a difference. But it wasn't the way that I wanted to wake up at 4am. I ordered a Hydor Smart Level ATO, which came in today. So far it seems to be pretty nice. I like not having to rely on a float switch, though I am going to wire one up to the Apex to disable the ATO if the float switch gets kicked on.
Nitrates are still on the rise a bit. Tests today showed 0.75, phosphates still hovering around 0.17. I'm only at 120 mL of pellets, so I'm adding another 120 mL tomorrow. Still feeding LRS once daily and pellets once daily. Fish are fat and happy, corals look pretty good.
Finally got the skimmer dialed in. Coralvue says that it should sit at 7.5-8 inches of water, but I couldn't get it to stop skimming super wet when it was that deep. So I dropped the water down a little bit, to around 6.5 inches, then dropped the power on the pump down to the 4th notch. Now it's pulling the type of skimmate that I want. Unfortunately, a replacement o-ring that they sent me was the wrong size, so I'm still fighting the battle to get the right one. But it's working well enough for now.
Still seeing a bit of cyano in one of the areas of lower flow. But I'm also seeing a fair bit in the sump. So I'm going to dose another bottle of Special Blend to see if I can combat the bad bacteria with some good. I'm also looking at an MP10 or Jebao RW-4 to put on the back glass to counter the low flow.
I also need to replace the return pump. I'm running a Mag 12 and it just doesn't have the oomph that I want. By the time that it runs the carbon reactor and feeds the return, it doesn't really churn the pellets the way that I want. I don't really want to go with a DC pump, but I might give a Jebao DC 12000 a try.
The final decision right now is what to do about my bully of a Foxface. He's picking on my blue-jaw trigger and stressing out the trigger pretty bad. The trigger is super docile, and he's by far a more preferred fish than the fox, but I don't really want to get rid of the fox either. I'm going to add another structure of pukani rock (assuming I can freaking find some!) and see if that gives them a bit less aggression. With only having the one structure, it's a lot of fish that flock to a small area. The second two-boulders formation doesn't seem to interest the fish at all. Fingers crossed.
Anyway, long and drawn out, but things are pretty good.
