Here's a video of the bell siphon cycling. The "white noise" you hear between burps are the LED light fans. They make more noise than the airlift, which is virtually silent, as does the air pump. ...

The LED shipment from China got held up in Customs in Chicago, and didn't arrive until yesterday. We're snowed in here today, so I'm going to post some photos of my current prototype, and give some...

I've found two sufficient for small scrubbers, one pink and one red. The real plus for me other than price and simplicity is they virtually eliminate screen burn. It's a nice, even glow.

>>>>As far as wall warts, I've been using anything I can find that is 12V and at least 1 amp, 2+ amps are better. The LEDs draw approx 1/2 amp for each strip. I just cut the 12v plug end off the...

I've been playing with algae scrubbers for a few years now, and have built about two dozen dedicated and more than a couple of hybrids. I started with a converted HOB AquaClear filter, which worked...

The nano has been up for a week now. The scrubber is working flawlessly, save for a trimming of the screen for a better fit. I scrapped the filter frame, and just put the screen in the slot...

I didn't want to have the heat added from an epoxy dip array to such a small tank.

10 months. Use Sea Chem Reef Complete, Reef Trace and Reef Plus @ 1/2 dose, alternating schedule. Also supplement Sea Chem Flourish iron.

I have had an odd couple as the only large inhabitants of my 33 long reef. The snowflake eel has grown large enough to try to eat my thumbsplitter mantis. The eel got thumped on the nose trying to...

I have a piece of prismatic plastic I'm gonna put in between and raise them an inch or two. Should even out the coverage. Before that, I'm going to put in new screens and see what kind of algae...

I'm a tinkerer, and have built several LED projects. My latest is a scrubber light for my horizontal flow scrubber that allows me to dial in each wavelength known to promote chlorophyll production...

2 cubes and 2 pinches. I also have several different macroalgae in my display tank. I supplement with iron.

The blue/white LED is an experiment that has me building a "tunable" LED array that...

I've been running a horizontal flow scrubber for about 4 months now. It services two systems, a 33 and a 55 tied together in a continuous loop. An 800gph pond pump provides flow through the loop. ...

It will grow back faster since there are algae cells on the screen. I just swish mine off in a 5 gallon bucket of saltwater, then siphon off the 'pods with a turkey baster. My screen is always...

Checked the screen last night. Right in the middle opposite the light was a 3/8" diameter clump of bright green very bristly stuff that can't be anything but turf algae. First appearance of turf in...

Sorta. One school of thought says to run powerheads on the lift tubes for a few months, then remove them. Something about nitrifying bacteria yada yada yada. I just want some circulation thru the...

I have more in this system than I've ever had or seen in any other. My Mandarin needs to go on Weight Watchers.... ;-)
I put one bag of Doc's Eco Matter in when I first set it up. I watch them in...

I've almost always run DSB over a plenum in my reef tanks. I use a simple airstone bubble lift, no power head. I've never had any negative experiences with them. In my current setup it seems to...

Not enough red light. Get the 10w hybrid 660nm you posted earlier. That's what I run, and my scrubber grows algae like crazy on a 64 sq in screen.

The scrubber will definitely deal with the phosphates. Did you rough up the screen really well? Makes a big difference. I use a coarse tooth saws all blade, and scrape both sides up and down, back...

Chaeto is going to compete for nutrients. I don't run any. I have some naturally occurring macro algae in the display tank, but not much. Try pulling 90% of the chaeto out. What's shining on the...

What other filtration do you run? Skimmer?

I turned on a fairly dim light over my refugium tonite and was astounded by the number of pods in the end chamber that drains into the tank. There's some rubble and a couple of gorgonian skeletons. ...

I've been running algae scrubbers for about a year now, first on a 40 breeder, now on a 55 reef. My current configurations hangs a 10w hybrid red/blue LED outside one end of a re-plumbed 6 gallon 3...

It's 8x8". I have a 55 reef and just plumbed in a 33 long to the system. My scrubber sits in one end of a 6 gallon acrylic 3 chamber refugium I've re-plumbed. Screen setup is same as yours, I have...

I'm running that same 10w hybrid LED on my scrubber. It's about 3" from my screen. Much closer and it'll burn in the middle. I'm happy with the growth, and especially the health of the tank. ...

Took a straight pin and poked holes in the air tube. Bubbles are about 1/8". Needed the bigger air pump after all :) Now have a nice curtain that cascades up the back of the screen, rather than...

Got a full width air tube and a bigger pump. Didn't need the bigger pump. While I had it apart I used a coarse tooth sawsall blade and tore it up pretty good. Looks nice and hairy now. Lots more...

Yes, have lots of bubbles trapped in the grid, and good air flow considering. Am going to go to a different air stone and pump first of the week. The pump and stone were salvaged from an old FW...

I've built a 40 gallon reef tank, and after reading some posts on various salt water community boards, decided to try and build an algae scrubber. My original intent was to convert the AquaClear to...
