Phosphorus dropped to 147 ppb (0.451 ppm Phos) from > 200 ppb after decreasing feedings on the auto fish feeder and skimming more wet. Nitrate 5.6. Gonna slightly increase the NH4 dosing.
Just did some chemistry testing.

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...
Bicarbonate in a 20g/L solution to about a 200g system volume tank. I started at 8mL/day and my nitrates went from 0 to 0.4 in about 1.5 weeks. I increased it to 10 mL/day recently. I’ll check next week and will increase it more. Perhaps my goal is 6-10 since my phos is around 0.06.
I started dosing NH4 as well since my nitrates have always been undetectable. My corals have responded well and have been gaining their color back over 2 weeks.
Added a Swallowtail Angel fish and a baby Biota Golden Lined Rabbitfish. Didn't do my research on the rabbitfish when I bought it. It will be too big for my tank in the future.
I originally got this hammer around 2019 with 2-3 heads. This picture is from 2023 of the mother colony split into frags. The current colony is from one of these "frags."
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.
