How much screen does one 50 watt flood light up? Sounds epic to me.

Tank is almost two months old. I've got a dottyback and a damsel, a green brittle star, leather, xenia, capnella, red mushrooms, and GSP, but the zoanthids are really thriving like I've never been...

I think I over-skim. I have a 4-cube scrubber, and for the past couple weeks I haven't been feeding that much and it grows brown. I've also been messing around with vitamin C, which is a weak form...

Take protecting these things from water very seriously. When it says "Don't use in the dripping water or dripping irrigation place to avoid light damage [sic]" I read "No algae scrubbers," lol. ...

The scrubber is on the back wall. I put a couple light bulbs against the glass. It's the corals that are going to use the sun, not the scrubber. I want leathers, zoanthids, colts, mushrooms, etc. I...

Soft corals lit by the winter sun

A 40 gallon breeder fits perfectly on my woodbox. Thing is, the woodbox is opposite a 20-foot wall of southern windows. I've had half a dozen freshwater planted...

I have a scratched-up acrylic tank that I was going to drill and turn into a 20g macro algae garden since my chaeto still grows. I'm probably just overfeeding, to be completely honest.

Yeah, all I know is Amps X Volts = Watts, lol. Electricity is not my area of expertise.

As for wether or not they work, I'm not entirely sure. My display tank algae is dying off, but my egg...

I built a kalk reactor (leaky PoS) and had to keep my outlet higher than the reactor or else it would drain a little when it stopped pumping to stir. The issue became that the reactor was taller...

That's them. I got them from DH Gate, which is a Chinese importer, I think.

I put one over my betta bowl for a while. The plants loved it, and my blue and red betta really was looking good under...

My sump is basically an empty 20g long with a 2" bulkhead for a pump intake. I have always gotten black cyanobacteria from the light spill. I added a cheap 265gph pump to stir the sump up and help...

What are the effects of adding chemicals to drain lines that lead directly to the scrubber?

I would think that alkalinity supplements could burn the algae, or does it just wash across so quickly...

I put a surge device on my frag tank so the water over the scrubber slows to 200gph over the 10-inch slot then surges at about 550gph (30-second cycle). I think the algae likes it, but I don't think...

I plugged them into a meter, and it said they were pulling 15 watts combined. I guess the 15 watt each rating is on 220, thus my 110 is half power.

I changed the black plastic canvas to clear...

I use Seachem Fuel that I had laying around. The bottle says it supplies both immediate iron and time-released iron.

I'm dosing a little Seachem Propel (iron) to see if that helps, too.

Lights are still way too strong. After digging through some of the LED info on this forum, I think that I should have more like 10 watts, not 30. The lights are 1.5" from the screen, too. I've added...

Yeah, I have a fan going. Without it the tank barely evaporates anything.

I think I need to split my photo period. The algae grows green in spots but the surface burns and turns pale brown/grey....

What kinds of fish? I've put all sorts of crazy things that wouldn't be considered "aquarium safe" in tanks with the more standard freshwater fish (tetras, mollies, gouramis, danios, etc), but I...

Between the 1st and 3rd cleanings my alkalinity went on a wild ride. I was dosing 12tsp of Reef Builder to a 125 gallon system per day at one point (which supposedly raises kh by 2 meq/L or 5.6dkh)....

Here's my new baby. She runs on my drain lines, flowing about 500gph over a 10x5-inch screen. Water flows into the slot pipe from both directions and "piles up" in the middle of the screen a...

Cleaned my new scrubber for the third time today. I have a very strong base coat of brown on the ruffed-up portion of my screen, a few spots of green showing up here and there, and my nitrates have...

I started my system with a scrubber and a skimmer. For the first 6 months of running this way, the skimmer would go for a day or two without skimming anything then all of the sudden overflow with...

When we say "cube" are we talking about a frozen cube just dropped into the tank? Or do we mean only what's left after carefully thawing and rinsing the frozen food? How big of a difference does it...

It took a while to find the bulbs with 100s of LEDs that will run on 120V, but I did it. 30 Watts of LED on a single-sided screen should handle 2 cubes/day I figure. I'll go double-sided as my frag...

Hi folks, I'm a long-time reader, first-time poster.

I'm moving my algae scrubber to run off my drain lines instead of return line. I want to go to LEDs on the new scrubber, and I found these e27...
