That is something else dude. It is good to see such a wonderful setup maintained without all the other chemicals people say you need. I am dosing calc, kh and mag at the moment and using a good salt...

The main benefits to using LEDs themselves, is that you can create a more even screen coverage, The heatsinks and LED's do not require so much depth as a CFL so will go into tighter installations....

Im no expert on all the exact biology, but i tried sugar dosing at one point whilst running a scrubber. This was to try and knock the last of the cyano out that i had. It seemed to work, but if your...

The revisions you have are spot on i would say. I ran a 10" x 8" screen with 10 x 3w 660nm per side for about 5 months. Then upgraded to 19 per side which i have now, with some very good growth. My...

having said that, i have just found https://public.sheet.zoho.com/public/cdm2013/ascalculator-xls-1 on the sticky page which wasnt there before.
As long as you go closer to the maximum than the...

Without having read all of this thread top to bottom, i wonder whether it might be possible to made a hard and fast rule regarding led power to square inches on scrubbers, as 1 x 3w for 3" x 4" seems...

4060 two mp40w es opposite ends on anti sync reef crest mode set at about 75%. After treating the cyano just have some brown diatom algae on each end of the tank glass. It seems to be phasing out...

Thank you for that reply. The video I watched was outdated and was using a bucket and dark screen with stiff dividers up the side. It wasn't long since I updated the LEDs from 10x 3w per side to 19x...

Does that look like the right type and amount of growth then? Am I right to scrape clean one side every other week?

Feeding is as above, as little as I can keep the fish alive on. It is a 300 litre display with total volume of 350 litres. Flow is with two mp40s in anti sync. The cyano has gone now only some...

P.s. i would not say that any of it comes off loose. I takes me just under ten minutes of bloody hard scraping per side as it is welded to the mesh. I am running an aquamedic multi sl skimmer also,...

Although i have done 2 years of research into this, i think i may have misunderstood the cleaning process after watching a bud carlson youtube video.
This is my screen:

I would like to thank Santa Monica for the advice. After increasing the light to my scrubber, on his advice, I got a dino plague which if I'm honest, I was quite annoyed. After clearing the screen...

Well, I have just finished a 21 day cycle of fauna marin algae x, and now I obviously have to restart my scrubber from scratch. It seemed to have done the trick though. I will let you know if there...

Can do. Would it not benefit me to remove all waste that might contribute to dino food? I think it's just because I didn't stir the salt and got to the bottom. I was manually dosing but haven't done...

Yes, running a turboflotor multi sl. Is it best to run this at same time? It's pulling a fair old bit of crud out.

Well, through the roof actually. I figured it was high as I am using the bottom of the bucket from d and d without properly stirring it first. Have done an awful lot of water changes to try and...

Santa Monica, you were in on the other thread I made about increasing the light and the hair growing brown. I had to clean it today, which was three days from the last cleaning and all I got off it...

I'm having a problem with this dino stuff to plague proportions. It started as I didn't have strong enough light, but don't think it's going to correct itself, now I have the stronger lights. I was...

Ok. I'll give that a go, and what to clean it every 3-4 days if there is some growth until it either goes green or all dies off?

I would agree with that, only the growth is so thin, it can't be more than the screen width for a weeks growth. Does this make any difference. I would understand if I had an inch of growth, as this...

Right here goes. Before =3617 and after = 3616
One is before, and one is both sides scraped as much as physically possible. I am quite satisfied that the bryopsis has a sufficiently roughed up...

Its gonna be a bit hard to do until next week now, as there will be some growth on it now, and its not that easy to take off. when i scraped it back to the bare screen, all of the wholes have a dark...

Two things i missed. The display tank picture is after two successive 20% water changes, one yesterday and one just done. and the last picture of the lit scrubber is after a one sided scrapping i...

Quick refresher. I am running a 350 litre system with a custom build sump to incorporate the scrubber. The scrubber is 10" x 8" roughly, and up until recently i had 10 x 3w leds per side on a...

Yeah, have a bit more than an inch below the waterline, but it still rushes down and creates some bubbles. The flow is what's recommended, but still get them. I will look into adding an under at the...

Hi, short introduction. I have a 88 US gallon system, with a custom built double sided 10" x 8" overflow scrubber into a sump section. I have 30w of led power either side. (8x660nm and 2 x royal blue...

If that ratio is correct about nitrate to phosphate in terms of turf algae absorbtion, then live rock and deep sand bed should have a negative effect on the scrubber and for the bio balls seem to...

Hi. Can I ask as I am just starting mine, how long to expect. And how long are those pictures taken apart?

I have done it ok, but forgot to update you. Wired the two white outputs to the potentiometer and the red and black at either ends of the chain. They work perfect and so does the dimmer and fan. Job...

It's a long read and lots of calculations but it's a good thing to refer to. Thanks for that guys. Think I know what I'm doing now. Will try it a bit later on

Ok. I thought afterwards there may have been too much, but I did press down quite hard with four fingers on the edge and wiggled them side to side to dispell any air.
As for the outputs on the led...

Hi. I recently ordered all the gear i needed to make two light screens for my scrubber. Got all the stuff from aquastyleonline, and now i'm in a bit of a pickle and need some help.
Have two heat...

Ok. Thanks guys for the advice. I have been planning and day dreaming about this tank for two and a half years since i broke down my last 5 ft one. (very sad i know). Back then i had looked into the...

Give me a relative size if you can. I.e. how many gallons you system is, to what size scrubber. What it's lit with (total power and colour) and whether it's lit both sides. Does it eliminate the need...

Well, im trying to look into making the led fixture at the moment. So far the only place i can find heatsinks is the US, and it costs more in P + p than the heat sink does. Might have to bite the...

I think maybe 10"x 10" is better, only the only premade fixtures I could find we're 12 by 12 and didn't know how to go about making one. I was told lit both sides a square inch to every gallon so...

Well not feeding anything yet, as it's a new build taking from my experience of the others. I plan it to be a moderate stocked fish rock and soft/hard coral system.

Dennis c, I have found the...

Hi there. This is my first post and im in the process of putting together my third tank, but with my first algae scrubber.
I was looking into using CFL's and reflectors, but a lot of research into...
