Justin's Aquaforest Oceanguard 790

Just added a Hydros start for more stability. I was using the Kasa powerstrip to control my ATO on/off before my scheduled AWC every morning, but sometimes it didn't turn off. This created 2 instances where I had to raise the salinity that lasted for like 3-4 weeks.

  • Hydros Start
    • Skimmer level sensor
    • Float switch to turn off AWC if draining doesn't stop
    • Leak detector to turn off pump + UV when it senses water
    • Control of ATO, UV sterilizer pump, fish food feeder
    • Monitor Temp

Looks good. Very clean build.

I found GHL fans get loud after a while if you dont get the dust out of them. Compressed air cans have worked wonders for me.
 
Just did some chemistry testing.

1/4/26
  • Alk 7.9
  • Nitrate 6.5
  • Phosphorus > 200 ppb (greater than analytical measuring range). I measured twice to rule out random error.
    • was 20 ppb on 12/16/25
Recently, I was feeding heavy and dosing NH4 to increase my nutrients. I also added some dead rock from my old tank that was sitting in a closed bucket. It was bleached and cleaned about a year ago.

Corals are fine and are growing. Alkalinity consumption has increased slightly. There is algae growth, but I think it is normal. I guess i'll feed less to slow down my nutrient import. I had my auto-feeder feed 3x daily on a 2 minute feed + my manual feeding of frozen mysis. I've turned it down to 30 second feed after seeing that high phos reading. Feeding heavily really increases nutrients..lol. I'm already doing a 1.4% daily AWC (30-40%/month). I think I can control my nutrients by feeding less.

Gonna test again next weekend.

Also, added an airline from my skimmer to the outside to help with pH. I should have done this a long time ago like I did with my previous tanks.

Looks like you are using an Avast Plank as your auto feeder, are you feeding pellets with it?
