The first 2 are too strong. I tried a 75 watt in that style and the algae was clear. Weird .

This one worked great.

I've used both of these and they seem help me grow plenty of chaeto. Both are supposedly waterproof. Can't say for sure, but they have survived splashes without any trouble.

Costco was also selling some 2 foot panels that I think were labeled as waterproof. They seemed like a great price for the output.

@SantaMonica offers their GEM5 lights without their scrubber! They are waterproof.

so I am starting to plan out my own diy scrubber and am thinking of running something like these lights. in daylight temp as i heard they grow the best. Please let me know what you guys think, but I do thing they are great for a scrubber build at a great price, waterproof too even

I experimented with dif color, wattage and types of lights. Think you’re better off getting a blue/red combo grow light, and one with more spread. Meaning more, smaller bulbs spread out over the area.

Like the one I posted above, or similar

I tried a light like that, 75 watt. Had to back it away from screen about a foot to get decent growth. Any closer and I got a clear looking slime instead of green algae.

Think the bigger the screen the better. More nutrient removal, maybe less frequent cleaning, and you could always put it on a timer to cut back if wanted.
Amount of flow is exactly why I like separate pumps. Figure in head and you’ll have a good idea of gph going over screen. There are formulas to calculate flow, depending on size of screen
