Need help with my frogspawn.

@Ipyloves I would try target feeding the corals too. I currently don't have any fish and when I did it was a pretty light bio load. I would feed several times a week. Sometimes at night and sometimes during the day and sometimes both. A cube of chopped up frozen mysis and I guess what would amount to about a half tsp of assorted powdered and pellet coral foods. My current system is about the same volume as yours.
You can also get nitrate and phosphate supplements if needed.

What test kits are you using?

Regarding your lights. Yes too much light can cause bleaching but it isn't the only thing. Your lack of detectable nutrients could do it also. Running two 60w lights at 45% power is less than 60w over a pretty large tank. There is no way your were frying your coral with too much light. I have an AI prime on a 5gal tank running at 80% which is about the same amount of power you were running on a tank 10x larger. It had a bunch of zoa I just got rid of and is LPS currently.

I would recommend you rent/borrow a par meter so you can properly set your light levels and map out the tank par for future reference. Once you get the lights set leave them alone and you can refer to your par reference map when adding new corals or moving things around.

I have a Red Sea Reef LED60 and at 75% and a color temp of 16k I have 100-115 PAR at the bottom of a Max Nano G2 XL.

Sounds like you can safely increase your lights. Just do it over a couple of weeks if you’re still at 45%.

I have a frogspawn about 8” above the bottom and it seems to be quite happy with the PAR there. It seems healthy and is budding.

I agree that higher nitrates and phosphates are likely going to make your frogspawn happier. RedSea AB+ aminos has produced a positive response in my frog as well. If you decide to try them, start at half the suggested rate and increase depending on how your tank responds.
