Sizing for Thailand waterfall scrubber

[billy mitchell]

question??? for a 220 gal tank for a scrubber that is 14"X 8" using 3w 660nm deep red leds 4 either side and 1 460nm royal blue led 1 either side of scrubber screen that is 10"x6"
connected to overflow with maybe 6k-8klph
this is what I am thinking so can I get some info if anyone has ideas...

Welcome from Thailand.

Is the size 14 X 8 or is it 10 X 6 ?

[kerry]

10x6 is pretty big. I feed my 150G pretty heavy 3+ cubes and have a 36" screen 6x6.

thanks for your reply
I have thought of purchasing a scrubber from you but by the time I paid for the scrubber and freight plus govmnt tax of about an extra 27% cause they charge on freight too it would put the unit beyond a reasonable price
the unit is 14x8" long with the screen 10xabout 6" the tank is 220gal with sump 54gal
the lights are led with originally 8x3watt 660 deep red with 2x3watt royal blue both sides but I think they may be strong...can alter because they are screw and plug in led's
so can alter their positions and pattern
hope this gives you an idea
have read just about everything you have on the net and all is excellent info

Pics are needed.

[billy mitchell]

this is in the planning stages ..have drawings of what I want but would like to get info on what size of scrubber I need for 220gal tank...eventually stock would be 12 to 15 fish max size 4" and a full reef with inverts and water turnover from DC octapus pump is 10500lph
as I have just moved from Australia to Thailand the tank I brought over was damaged in shipping so have a new tank and sump being delivered here on tuesday
so I want to have everything ready for when I start to fill tank
can email you drawings and how lighting would be too...have ordered led's plus drivers and sinks from rapidled.com
might be interested if you do an unassembled kit cause I know how to weld acrylic....unassembled might not incur a tax cause would be just pieces of plastic.and would be flat not bulky
would wait your email address and I will send drawings

Scrubbers are not sized for tank size but to the amount you feed. Have read the sizing guide lines thread, see it here this will help. http://algaescrubber.net/forums/showthread.php?1419-New-sizing-guidelines

No more kits available.

Figure your feeding first. If you don't feed the corals, sounds like 5 to 10 cubes a day.

[billy mitchell]

what do you call a cube I have a auto feeder so how many pinches = 1 cube

[billy mitchell]

ok I get it now...size and lighting is measured by the amount of food that is put in the tank per day and there is a minimum water flow rate too...yep I think I am nearly there
so if I fed 3 cubes which I think is 1cubic cm a day and maybe 5mls of coral food then I would require a screen of 350 sq cm =25x15cm and flow rate above 450lph ...led lighting is 14watt per side
how are these figures ?????

[SantaMonica]

Well coral food really puts a lot of nutrients into the water, so count it as 2 cubes. So you have a total of 5 cubes.

5 cubes would need 5 X 12 = 60 square inches of screen = 375 square cm, so you are about right. I'd double the lighting though, and be able to turn on half for low-power.

[billy mitchell]

ok that is great info I can make 2 separate light units per side ..and what I worked out is about right ...another question is..... more water is better and by your pic's of your scrubbers is the water pipe holding the screen has 1/8 slot and the pipe is 1"od ???the pipe from DT to sump on my aquarium which has an od of 35mm would I use this dimension..have a T piece ...one end going from DT to sump with gate valve at bottom to restrict flow .....the centre to scrubber or would you go from DT straight to scrubber with no restriction

[SantaMonica]

Yes the pipe holds the screen: A circular wrap of some kind goes around the pipe and through the screen.

1" OD, and 1/8" slot, is good. Rough up the screen a lot.

You can go from DT straight to scrubber with no restriction; just test it first before gluing.

i was glad i put a pvc gate valve between overflow and scrubber...because the first night i ran it ...it was very loud ...i was able to adjust flow so there was no gurgling noise ...i didnt have to interupt flow that much...

[billy mitchell]

thanks for the info...my 220gal arrived yesterday and they are going to do plumbing today but I think I better do it because they will be using 90 deg bends for return and return pipe is 3/4" and just one pipe...my pump is 10500 lph so would not be enough especially with 90deg bends
have you any suggestions on this...and yes I was going to put in gate and do stockman standpipe to quieten noise ......been there done that
