Folks, I regret to say I pulled the scrubber from my tank. After a year experiment. I got nothing. Surely it was a flaw in design ,flow. or lighting. My overflows have grown more algae in a year than...

I will get You a screen pic very soon. I just scrapped it.

Evening Gents, Sorry It's been a while since checking in. It'[s been about a year now,still the same brown slime on the screen. Now the rock pictured above no longer has any of the bubble or HA seen...

Best Wishes for 2016! No Sir the rock surely doesn't look that that pic any more. The bubble is just about gone and the HA is receding as well . Now I have this off white looking stuff now but...

Ok, Thanks, That will be my next step. Looking at the display, there are surely enough nutrients to go around! Like I stated in the past, this is an experiment and I'm open to any changes.

Evening Gents, I see a little HH along the very top of the screen. Most notable is the brown stuff is not coming back as fast as in the past. I "think" the lights on the display is out competing...

Thanks, I lightly scraped . will increase the lights on time.

Here is a pic, Again I thank You for Your time and op's! Now if I scrape all this off there is some actual green film under it all.

I agree Santa Monica, Slowly but surely it's going! What would You suggest as the best lights on/off time? I turn the lights off around 10:30 11 am then on around 4pm. Do I want longer lights on...

Evening , So I have som elong strand looking stuff but not the nice green I was expecting. I'm not scraping the screen weekly just letting it go to see what happens. I do scrub clean the very top...

Evening Gent's I removed the extra CFL and went back to the Led strips two on each side. I let this thing go for quite a while. This time I cleaned the slot which had green stuff clogging it. I...

Thanks Santa Monica, Surely there is enough nutrients in the water to kick off this scrubber? Is it possible that if I remove enough algae etc the scrubber will get enough nutrients? Still running...

I just cleaned this out of one of my overflows

I haven't cleaned them out in 5 years! This is why I think I have plenty of nutrients in...

YIKES! I'll work on all that! LOL

Ok that worked, remember I scrapped it just a few days ago.

OK here is a pic of the scrubber

Ok so about 6 days ago (as usual) I used a plastic scrapper to clean the brown stuff off the screen. So 3 days ago while the screen was still clean I saw definite yet light green over the entire...

Gentle men, Modesty forbids me to boast but I got some GREEN! Ya Baby!

Good evening, Ok , I have been experimenting with my scrubber since around February. All I get is this brown mulm(best description). I'm sure I have the excess nutrient in the system. I have lot's...

Thanks crusin, According to my Kits and "tester": My po4 is <.08, No3 0. The amount of algae in the display tells me these nutrients are all tied up. I was running M/H lighting and thought they...

My screen is 7" across the top and 12 down. I have 2 of the expressions running vertically on each side. they are mounted outside the box about 2.5 inches from the screen. I don't have any current...

Hello Gents, checking after some time. I still get just the brown slime. So 1st, I'm sure I have enough nutrients in the display. 2nd, I have good flow over the screen . It think it must be the...

So I removed the M/h lights and swapped them for led's.I thought I had too much light. Now,according to this apogee light meter I borrowed , I have double the light! I love/hate this hobby LOL!

Good Evening, It's been a while since checking in. After moving the light strips side by side, I have a little more green right down the middle but mostly the brown slim stuff. I think it's...

Ok so I placed the light strips side by side right down the center of the screen. They are as concentrated as possible.

Thanks, The lighting is another aspect I haven't looked at. I also scrubbed all the brown off. The screen felt very rough to me. I will concentrate the lights ans see what happens. I'm close to...

Hello, Checking in. I have the same brown stuff with "A little more green" This is a slow process for sure. Not sure what I will try next. Lots of options !

CJ, Thanks for the insight, I know what You mean by "blasting water" rushing down the screen. I want to try a wider slot for a thicker,even water column . Every morning I have water squirting away...

I got the bigger pump, a mag 7. I got 450 gph off the drain. The big site's headloss calculator said 420gph. Pretty close in my opinion. This is a marked improvement on the flow. I will wait a...

Hello,I ordered a larger pump,Should have it Tuesday the 28th. According to the big site's head loss calculator, I will have around 42 gph per inch for a 10 inch(across the top) screen. The pump is...

The figures posted are per inch. I understand the need to clarify.When I ran the test without the screen, The water blasted out along the entire slot. I "hope" the pump is restricted by too small a...

Good Evening. I did a flowrate test today. The screen is 7 inches along the top. I came up with 28.2 gph, Not enough. I removed the screen and got 36 gph along the top,still not enough. I propose...

Thanks! Will do. Also I have had issues keeping the 18/ 6 lighting schedule. My fault. This is an experiment to me. I'm in no hurry to get results. I am enjoying the challenge and learning the best...

Hello, Been a few weeks since I checked in. Had spraying issues redid another manifold and installed a spray guard.Still have the brown stuff. I do have some green but its right at the top inside the...

Thanks, I will address that.

Hello, I guess week 7 now? So I cut the screen down to 7 inches as stated last week. Was really able to concentrate the lights and improved the manifold for better flow .More brown stuff but more...

Good evening,I cut the screen down from 9.5 to 7 inches. I was able to concentrate the lighting greatly. I will give it a couple of weeks and see what happens.Thanks

Thanks Again for Your advice. The screen is way big according to the new sizing guide. I will cut the screen down. This way I can use a shorter slot in the manifold which will create more flow over...

week 6, looks the same I do have some bud looking spots still brown though.
http://img.photobucket.com/albums/v240/upsguy/003-5.jpg
I think I will wait one more week and concentrate the lights on...

Thanks for the reply! There isn't much change. in fact there is less this week than last. Not sure what steps are needed to refine the design. I run 18 on 6 off. Surely there is plenty of light....

week5. looks about the same. Thanks

Cool, So It's cooking! Thanks

Hello ,4 weeks now , I had to remove the screen from the manifold due to a little green stuff clogging the slot, however the rest of the screen is still brown just more of it. I suspect I don't have...

week 3 now, went to 18/6 schedule. Barely got some almost green looking stuff! I lightly scrubbed in saltwater and put it back. Hopefully I'll have a something worth a pic next week! thanks!

Thanks for the specifics!

Just how much dark time do I need?

Week 2, Just more of the brown film. I lightly scrubbed it off and will increase "Lights on" duration.

One week now, There is a light brown film covering the screen. I assume this is Diatom. Not enough for a pic Yet.

I received the expressions leds today, They are very bright indeed. I installed them" outside" the scrubber,They are 2.5 inches away from the screen the light passes thru the acrylic. There has to be...

Thanks Santa Monica, Interesting that You foresaw the drain gurgle issue. The drain ended a few inches below the water level of the fuge and did gurgle. I adjusted it so the water drains right at the...
