Frogspawn problems

[sajy]

So I got this frogspawn (I think it is a frogspawn) about 7 months ago. When I first got it, it looked healthy, then I'm pretty sure I bleached it with my light and it turned almost white and began to recede. Fast foward and I've moved houses and got my tank set up again. I was scared to use my previous light and switched to some basic aquarium light from amazon. Honestly, it's worked pretty well for the last 4 months. My zoas are happy and so are my favites. My frogspawned gained some tissue and started to color up really nicely. However, now it looks like a cone? My first instinct is to say that it is reaching for more light. I wanted to hear some thoughts on this. I do a water change every other week and I test then too. My salinity is 1.025, dKH is a solid 9.5 and my nitrates are ~30-40. The light I currently have is

SEAOURA Led Aquarium Light for Plants-Full Spectrum Fish Tank Light with Timer Auto On/Off, 18-24 Inch, Adjustable Brightness, White Blue Red Green Pink LEDs with Extendable Brackets for Freshwater​

from amazon. I don't intend to stick with this light as it's not even made for corals and I took it from one of my other freshwater tanks. The light I had before was a

Phlizon 165W Dimmable Full Spectrum Aquarium LED Light Fish Tank LED Reef Decoration Light for Saltwater Freshwater Fish Coral Reef (20"x7"x2.4")​

It was expensive and I'd like to try again, but I don't want to burn them or cause horrible algae growth. Any tips on settings for the Phlizon that doesn't burn corals?
(One of the heaters in my tank doesn't work I just haven't pulled it out yet lol Frankly forgot it was there)

what size is the tank, how many gallons?

It's a 20 Gal

The freshwater light probably isn't going to work long term for anything other than maybe soft corals at best.

The Phlizon light is way oversized for your tank. But you should try it again and set it to about 10-20%. Probably start around 10% and slowly ramp it up (over weeks) to around 20% and see how everything reacts. It def has the ability to overpower your corals for that size tank.

I don't know what that coral is, but it definitely looks like it is reaching for more light.

I had a 40 gal before this one that had the Phlizon and I made a rookie mistake and used a brass fitting on the sump pump for it and couldn't figure it out for a year. So I shut down that tank. I figured it was overkill for the 20 gal, but I hate to buy something else when I spent good money on this light. Thanks for the advice!
