My first zoa (Rasta) added a week ago, is under a Maxspect MJ-L260 for 8 hrs at 50% intensity, amonia and nitrite at 0 ppm, nitrate at 20 ppm, salinity at 1.025 ppm, kind of worried if it's doing okay or not, please share your thoughts and suggestions, sorry for the blurry image and video

No need be sorry for the blurry video and pic, it happens😉. Anyways, looks good, I would observe it for at least a few days, though.
 
Why do you run lights at 50%, are you lights double as strong as needed for your tank? If your lights are the correct strength for your tank then they should be up around 80%+, why run the lights at only half strength.
 
Are you testing any other parameters?

Any other corals in your tank?

You don't need to test nitrite anymore; your tank is cycled.
 
Phosphate would be the first thing that comes to mind. In new tanks it can sometimes be depleted when calcium carbonate of fresh substrate or rockscapd aren't yet saturated. When a lot of old rocks were used it's also possible that phosphates are elevated. In that case placing the Zoa in your tank would be like a sudden phosphate spike which corals seem to hate.

One important thing: If your tank has not yet gone through the ugly phase the coral will have some stressful times ahead. First diatoms which can compete over nutrients if they are sparse and then green hair algae which can even overgrow weakened frags.

Thank you so much for your inputs

Mine is a 30 gallon tank and I'm using a Maxspect MJ L-260 for 8 hrs, planning on increasing the light evenually in the upcoming months once the tank matures a bit more, don't really want an algae burst
 
Maxspect MJ L-260
According to google that is a 63 watt light, I use 100 watts over my 32 gallon. Noted for the algae, but keep in mind corals and algae need the same thing, so if you reduce the light to diminish algae the corals will also suffer.
 
Mine is just a 2.5 month old tank, kind a worried if I increase the light intensity, something might go south

Just be patient, take your time😉.

I run my lights at full intensity on my 20g tank, a lot of hair algae but the corals seem to be happy so I just manually pull out the algae and turn them into nori like sheets! Those sheets i will then use to feed my shrimp, conch and urchin.

I dont think anything bad, other than algae, could happen by increasing your light, but also dont do it too quickly.

Patience is key.

Its been a few days now, how's the zoa doing?😄

Unfortunately I don't think this is a winning strategy for trying to prevent the uglies.

The zoa needs light to thrive and by trying to control algae in this manner you're starving the zoa.

Zoas are some of the hardiest corals I’ve had. They enjoy dirty water and usually survive a tank crash, all of mine did.

Turn up your lights, under lighting a zoa will result in it stretching for the light and large polyps. More light will give you smaller polyps.
