Too little or too much refugium lighting?

[borillion]

Biocube 29 I stuck some chaeto in the rear middle chamber intank fuge basket, cut up a 3 tube red blue and white led light fixture from Amazon.

Grow Light for Indoor Plants, 198 LEDs Full Spectrum LED Grow Light
Amazon product ASIN B089Y928XD
Normally you can only light up the red + blue or the white but not all strings at the same time, but I wired them all up to run together.

The first pic here is using 5v @ 4A with all strings lit.


The second more red tinged pic here is using 5v @ 1A with all strings lit.


Is the lighting in the second picture sufficient to keep the chaeto alive if it's exposed 12+ hours, or should I go with the higher power supply?

Test both for a month and see what happens. They make waterproof grow lights and sell them on Amazon for 30$ grows weed too, or at least that's its intended purpose. I wouldn't know though, mine is growing a few varieties of algea instead.

ahh the ole "saltwater weed" eh?

Well I guess so too little light, All of the chaetomorpha algae I purchased disintegrated. Though the green hair algae has no problem growing at all in the display tank. I thought that 12-hour cycle was enough.

 

[YOYOYOReefer]

probably too strong of light if it disintegrated.
or your lights too close to the cheato.

Are you adding chemikills to the tank as well. I put algearid in my tank and nuked eveytype of algea I had, so it accomplished its purpose.

I doubt it was the light that caused it to disintegrate. I have been keeping cheato in a tub with a cheap freshwater light for 3 months now and alive and well as i dosed vibrant in tank . Some other condition killed it.

 

[borillion]

I haven't dust vibrant for weeks and it wasn't in there when I was.

The hair algae grows without problems so I'm perplexed.

Maybe the light isn't bright enough?

Here's what am using its mounted like a foot above the tank maybe more.
