Instead, place the diffusion material on the scrubber housing. You can try several things but start cheap. Blue painter's tape, or plain masking tape. Just a 1 cm square, right in front of the LED chip. If that works, then you know that is a solution pathway to go down, and you might try something a bit more permanent

Thanks Floyd, I'll give that a shot.
Purely out of curiosity though, Why would it all of a sudden happen? I was getting nice thick growth, then it went to that slimy snotty stuff which cleared the screen in the middle.

Could be a change in tank chemistry over time. That tends to happen when you add a scrubber, so conditions might have been good for growth at the light level you were at, and then over time that shifted.
Have you tested potassium or any other elements besides just N & P?

I have not, besides iron which I started adding thinking that might have been limiting my growth.
The light cycle itself is fine then (23 hours split between the front and back light with an hour of both off)? Just diffuse the light some so it's not such a bright hot spot?

It's not intensity, it's something in the water that some tanks just have, or get. I'm working on a mineral supplement to help get through this, and if you'd like to try it send me your address and number of gallons you have.

The light is so weak there that dark slime can still grow.

I'll beat you to the punch here. Take a teaspoon or two of Miracle Mud, mix it with some RODI, and dump it into your return pump chamber and let it blow all around your tank. ^^ do a bit of research on this one and you'll find that people are actually doing this and having some interesting results, and not necessarily with an algae scrubber involved. I'll have to dig up where I read about this...I would read up on it before doing it though. I just wanted to throw this out there.

Hi All,
I'm setting up a new 40gal ish AIO tank and want to use an upflow ATS, I'm mulling a couple of designs and could do with some input. The basic design will be a 4"x4"x14" removable box that will drop into one of the rear chambers. It will be lit via a DIY LED fixture on the outside of the glass (10mm optiwhite if that matters). Water would flow in the bottom and up out the top as part of the main flow through the rear chambers. First design would use a standard screen (not drawn in the illustration) that goes in the slots and would lift out for easy cleaning, usable screen size would be 12"x3.5" (42"square) and an airstone/bubble making device inside the tube at the bottom to protect it from the light and increase time between maintenance The second design utilises the same drop in box but instead of a centrally mounted screen it would have the screen mounted around the edges (or the faces coated in crushed quartz) and a 3 sided bubbler, again protected by a tube and would offer around 126" square of growing surface. What I'm struggling with is choosing the correct sized air pump, and whether I should be using an airstone or other bubble source? Thoughts on either design?

Between those two, the second is much better because the first has a dark side which you don't want. If however you changed the screen on the first one by rotating it 90 degrees and therefore lit both side, it would be better (2-sided is always top priority).
Airstone is ok, and easy, but bigger bubbles are best. 1 LPM would be good with a small screen, and 2 LPM for the 3-wall screen.

No there is no space behind, and therefore no place for algae to be dark.

Could the first one be used with a solid screen rather than a mesh screen to make it truly single sided? I'm just concerned 120sq" would be massive overkill.

Yes if the white screen had a black backing to stop light from getting to the back side.

I would like a little advice on my Algae scrubber. I seem to only get dark slimy algae on the screen, but get the more desired green hair like algae growing on the bottom plate. My tank is 180g I feed about 2.5 cube equivalents per day. My nitrate level is currently 20 and PO4 .05-.07. I had been running the lights 20 hrs per day for the past month and I am thinking about going to 24.
The only nuisance algae that I have in my tank is a little bubble algae and whatever grows on the back glass which I never clean. My hopes were that the ATS would help keep my nitrates a little lower in the 5-10 range. I am running a little phosguard to help keep PO4 below .1. I have been running the ATS since early September. I run Kalk in my ATO to maintain calc and alk. I change 25g of water every 2 weeks. |

Is that coraline algae on your screen? It looks purple. I'm not sure if green hair algae will grow in the places where the purple is. You may have to somehow remove the purple somehow.
I think the brown slimy stuff is bacteria and should be brushed off to help encourage/allow the green algae growth. Sent from my SM-G930T using Tapatalk |
