I did a water test a few days ago. All looks good except for Nitrate and Phos are high. I was feeding frozen food 3 cubes a day on top of feeding 4x from the auto-feeder. I have cut down on the frozen cubes to 1 to 2 a day. I'll give it another test later next week. Everything else looks good. I have been dosing AFR in the mornings and Phyto at lights off. I have also been dosing Manganese and ammonium (stopped for now until Nitrate comes down).
I also started to look into battery backup options. I don't remember the last time we had a power outage in New York City but I think it was like 8 years ago. I'm planning to get one of those power stations to run the return pumps. It looks like I will need to do some tinkering with Hydros to make it work. I found a DIY guide for it.
