Horizontal scrubber options

Hi guys, can any body suggest or point me to a successful horizontal scrubber?
The reason I ask- I have frag system with multiple tanks draining to a sump turning over aprox 2500 gal hour in two returns, i would like to use the return water to supply the scrubber, I have considered a vertical but the small risk of a blockage would not be good, I'm not saying no to vert yet but leaning to the former.
I have read of islanding with horizontal but will high flow rate stop this?
Screen size max space 26l x14w", and run a 130w cfl reflected, or a 150 halide 10" above screen.
I have screen mounting options of submerged, surface, angled, could even incorporate up flow with or without aeration.
I have some of the recomend screen that would be glued down or alternatives?
Any suggestions? Can this work or vertical only way?

Thanks

Welcome,

A pic of the place where it would go would help. Also, your build skills, heat, stray light, salt spray, and noise need to be considered.

Islanding is reduced by higher flow, and by narrower walls, or even by guides like this:

Yeah I'll get a pic up. I have some baffling now that controls water very good, no spray and sheet flow, I prob could have about 3/4" of water traveling over plate 14" wide.
I bought some led grow lights 225x.06w if they don't work for this one(height penitration) i have another display run them on

i have also just thought it might be possible to run a light under sump to shine on underside of screen, cons- Flood, already have heaps of room on top side, and more work ;(

Well if you already have a lot of flowing water, then a horizontal might be best.

26 X 14 is very big, and you need to light the whole thing brightly or else the dim areas will grow dark stuff that lets go easily. So a large 100w LED grow light would be needed, two of the 50w grow lights, shaped 12 X 12 each, would fit.

Thanks SM
Do you have a particular light in mind?
I can foresee an issue with getting that whole screen going nuts- Nutrients, it's going to need a cup of food a week to run it! Although mainly corallimorphs and zoas, I don't think they'd mind
I could cut the screen size, but the difficultly is light then, trying to focus usable light at 10" on screen.
Vertical is looking easier lol

Hi - this guys got a successful large H - scrubber on his reef set up

Thats some insane sps growth in his tank, scrubber page 29.
One thing though its an sps tank and im reading a bit in here that softies dont do well with scrubbers, but there's always a "but". Im a sold skimmer less person for 3yrs, havnt looked back, and saw the scrubber as another tool in the box of natural success.
Is this going to destroy my corallimorphs and zoanthids from a lack of nutrients? Or just adding a heap more food to compensate is the go?

If anything it's xenia that have trouble with scrubbed water. But zoo's and mushrooms seem to be fine. You just need to try it.

Hi Money

Nothing in my mixed tank has been affected by switching to an ATS & Skimmer set up.

Xenia, morphs, gorgonians, LPS, SPS and a blue maxima clam.

Like SM says, Give it a try.

Cheers

So two of these? Or one 100w? Light will be 10" above screen, or I have 2x 14w panels that I was going to use setting up waterfall type above seahorse tank that will be joined to 190g tank

2 of them, 3" from the screen. The 14w ones won't work at all.

Can't go lower than 10", sump fills on shut down.

then you are better with floodlight LED growlights instead of flat panels.

100w Flood light http://www.ebay.com.au/itm/321254933...84.m1423.l2649

big enough? anyone used this particular one?


Saw this single sided scrubber http://algaescrubber.net/forums/show...Sided-Scrubber

I can run light through sump side 4" from screen, id make it 24" to get the flow, 6" long and run two T5, or 2 of the full size canvas panels with 2 of the led panels you listed SM

Im not into experiments when there's tried and tested, it seems like it might be hit miss with horizontal so............, what you think?

sorry for the questions, id like to nail it the first time

Those lights are good. Although the whole room will still be red, and, you'll get growth in other parts of the sump too.

I can't see the scrubber link; pics are removed.

You want at least 50 gph per inch of horiontal, so at 14" you only need one of your returns. Epoxying some 3" strings to the surface will help attachment also.

its been awhile with not a lot happening.(Edit a lot happened- i added a 1200lt display tank to the system, now total volume 2500lt), i Just got off my butt to try single side, there is diy lights atm, but have a 60w Led panel on its way, i have tried to reduce bubbles and going to try more yet.
Its behaving very similar to an up flow, at a guess 5000+ water passing over it, Can i have to much air and turbulence?

Attachment 5682

Looks like a water fall now.

No, can not have too much flow or turbulence.

Cool thanks SM, my main concern was if air bubble size was too small it might obstruct light, on flip side it might be better as light is passing through bubbles deep into turf. I assume it will also help spread my light acting like a diffuser

LED been running for a few weeks, patch in middle doesnt look happy, Less hours?

Attachment 5764

It's burning in the middle, and not enough light on the rest.

If you could back the light away, it would help. Maybe also surround the light with aluminum foil to direct the light to the outer parts of the screen.

Ill give it a go, thanks sm
