Just so there's no confusion, the lights that I posted the link to are NOT the lights that I bought. I meerly posted that to show what my lights looked like because someone was asking about a heat...

These panels were purchased as is, not assembled by me. There is no heat sink. LED's are soldered directly to a PCB. They are low watt and don't generate much heat. These are similar to what I...

Ah, PBT, yes it seems happy. Hippo Tang is passing him up in size now. Was commiserating with a friend who just lost his job and watching my Red Wings loose to the Black Hawks. Anyway, too many...

PBR?? Sorry, I'm usually pretty good with TLAs (Three Letter Acronyms) but somehow Pabst Blue Ribbon just doesn't seem to fit.


Floyd,

I'll take some pictures when I get home this evening. ...

I know this is an old thread but I haven't been on here in a while and thought I'd check in with an update. I sold my first LED scrubber to a fellow reefer that was having problems with algae in his...

Um.... This picture is from my algae turf scrubber filter. It's SUPPOSED to grow algae so it doesn't grow in the tank. Not sure where you're coming from.

When I do my weekly screen cleaning that the algae sheet is covered with bubbles before I turn off the supply pump. Once the flow stops the bubbles pop and leave behind sort of like pock marks in...

Dimensions:

The inside of the box is 4-1/2"d X 17"w X 19-1/2"h. The top, sides, and bottom are 1/4" Lexan. The front and back faces are whatever Home Depot sells that's close to 1/4", something...

Thanks rygh, I hadn't considered bulb refreshing in the equation, good to know.

whites, I've wondered the same thing myself about how far away they'd be effective, or if I could have used lower...

The reason I said I wouldn't recommend the LED solution is two fold. The LED fixtures are not inexpensive and I first looked at them thinking, LED -> low energy consumption. Well I'm using 100...

The Phosphate test kit I have is at least 3 years old so I doubt the results would be meaningful. As for the Nitrate test I always figured (maybe wrongly) that anything under 1 is good so I never...

OK here's the test results to date. All tests are with Salifert Nitrate test kit. Wasn't until I decided to get parallel results with the newly bought test kit that I noticed the one I had been...

Step by step cleaning. This took me 15 minutes including taking the pictures. (More than twice that to do this post)

Take off the lid....

Actually the bulbs on these LED panels are 8mm. Not shown in the photos is my custom cover to block the light from the DT since it's on a reverse light cycle. The reason there's no pictures of the...

"You recommended led? Wow
Only experimentally I hope. "

What am I missing here?

These are the lights I used.

My first scrubber, which I considered a proof of concept, was undersized but all I could fit under the tank. It was open air, lights were clamp on fixtures using CFL twist bulbs. When I started it...
