do have an air pump on it because my fish keep passing out if I don’t have it on.
This sounds like an issue. What do you mean “pass out”?

the tank light is on from 9:30am to 5:30pmThis I can tell is not a reef ready tank and has no sump.
Are you regularly servicing this canister unit? If you dont clean it every 2-3 weeks, you are quickly building nitrates which will feed this algae.
Additionally is the tank at or near a window?
Corallife light is literally all white and likely supporting the algae growth. How many hours a day is this light on ?
Are you using tap water from the faucet or RODI water ?
What is your phosphate level ?
Please answer questions before starting this below to find and prevent the cause.
I would place it in a container of tank water and pull off as much as you can and scrub the rest with a firm toothbrush and some 3% hydrogen peroxide.
Return to tank, reduce white light intensity and number of hours of white lighting and add some snails such as :
Astrea
cerith
turbo grazer
trochus
A Pencil urchin
8-10 Caribbean blue leg hermits
Reduce white light 6 hours and even turn off whites and run blue only for 1--14 days and do the steps mentioned above.the tank light is on from 9:30am to 5:30pm
i do use rodi water

What is the TDS of your RO water ? What RO unit are you using? RO or RODI ?
It’s an ro systemThe tank is not near a window
I’m using an under sink reverse osmosis drinking water system by eco water system.
Test that water for phosphate and TDO and see what level it is at.The tank is not near a window

thats going to be something that adds to your issue. with just water alone, you have material in the water that is contributing to the algae. you have nitrate into the water before its even added to the tank. i assume that is numbers are straight up RO water readings before adding to the tank, or adding salt mix.The TDS is 187 mg/l
10ppm of nitrates
Phosphate and TDO is unknown I have to get the test kit
