I was looking at this with reds and blues. I read this spectrum would be good?

My refugium is 36"x30". I have two 20w 6500k LED floods and 2 10w 6500k LED flood lights like I mentioned earlier in the thread. There is are two other 10w ones on there but it's not connected since I added the 20w ones. These lights sit on my acrylic lids and are about 6" from the water's surface. I could get away with much less light if they weren't so close to the water's surface and also not shining through a dirty acrylic lid.

In this refugium I have a deep sand bed, Chaeto, a stunted mangrove and some other macro and what ever other algae grows in there.

The lights just started coming on and only half were lit when I took these pictures.

I actually had one of those and it was pretty weak to be honest.. I am trying the below, and while it indeed does grow cheato, it's not shaping up to be as good as my hps 150..

MarsHydro Mars300 LED Grow Light with Veg/Bloom Spectrum for Hydroponic Indoor Greenhouse/Garden Plant Growing, 132W True Watt Panel https://www.amazon.com/dp/B00XC3LBI2/ref=cm_sw_r_other_awd_re4Mwb3C0AFB0

While these lights are terrific and are what I have been recommending, I am not sure that will solve your growth issue if my suspicions are correct.

I have to agree whole hearted.

I tried the 30w 6500k

A 45w e27 red/blue growlight

13w CFL

23w CFL

Added iron


And my chaeto will not grow, my GHA is also disappearing




So ill try a ATS now and use these lights for that. 250g total water volume and I only feed 1 cube a day.

5700k-6500K is day light or full spectrum.
3500K "“ 4100K is technically cool white although some refer to 6500k as cool white as well.


5700k-6500k is what you want.

Here is one that specifies it as 6500k. While they may look the same, I can say for certainty that they are the same.

Anyone know if you can put these right on top acrylic? Or do they get to hot

 

[kenneth wolfe]

I run a cheap clip on work light from Lowes, with a 5000k CFL day light bulb. I can keep up with my chetto its grows so much. I have friends that just started up new tanks and I told them not to buy any I will give them a bunch of it. That was just a week ago and now it looks like I never touched it.

 

[kenneth wolfe]

more light = more growth

Mine sit directly on an acrylic top without an issue. The stay plenty cool for that.

I am looking at ordering this lamp, say 5000K.
Opinions?
