micca Thanks for the feedback, brains613. I've adjusted my original post (Page 52 / post #770) with the information you provided. I'll continue to make edits as needed.

vladguan Guys, the same thing can be DIYed with a little bit more work using DWV pipes and fittings. You can make a large one using 6" diameter pipes and end caps and then some bulkheads and irrigation rises as the centre tube and then a small threaded adaptor to screw into the inlet.

Immortal1 LOL, guess I have not looked at this thread in awhile. Philip, yes the 10" housing seems big enough for my 75 gallon tank. What is the largest tank a 10 housing could be used on? No clue. Curious, what is the approximate cost for a 20" housing? and would (2) 10" housings produce better results if you could get the (2) 10" housings for about the same cost as the 20" housing?

Nice write up by brians613 - very helpful! Also, I find that the clear housings offer a chance to see whats happening inside the reactor. I have pushed too much cO2 into mine and it resulted in a bubble at the top of the reactor.

Which one on Amazon did you get?

Patriot Thanks for posting the list of what is needed. Now I have to find a clear one big enough for a 80 gallon tank.

I originally purchased the Whirlpool filter housing from Lowes and it leaked like crazy. The one I had didn't come with an O-ring. I'm unsure if it was missing from the box or if the unit simply doesn't come with one. Nonetheless, I returned that unit and got the GE one from Home Depot. It does include an O-ring and hasn't leaked whatsoever. I recommend you use the GE one based on this. The pictures below include the Whirlpool unit, but everything with the GE unit is exactly the same for all intents and purposes. All parts listed below were purchased from Lowes with the exception of the filter housing. The associated item numbers and descriptions are from Lowes. You can skip the shutoff ball valves if you want, but it's probably best to include them. You may need additional tubing for the outflow of the reactor to the tank. I recommend Watts braided vinyl tubing since non-braided may kink and cause problems with flow.

Water Filter Housing

At the time of this writing, here are the two most popular opaque water filter housing options that are available from Home Depot and Lowes. Based on my experience as noted above, I recommend you purchase the GE unit from Home Depot.

Available at Home Depot:
GE 3/4 in. Inlet Whole House Water Filtration System
Model Number: GXWH04F
Store SKU Number: 319246
Internet Number: 100471282

Available at Lowes:
Whirlpool Opaque Whole-House Pre-Filtration Housing
Model Number: WHKF-DWH
Item Number: 89374

--------------------------------------------
All other components (available at Lowes):
______________________
B.
Description: Genova 1/2-in x 3/4-in Insert Male Adapter
Item Number: 54137
Quantity: 2

Note: The 3/4" insert size is correct, but you may need a different hose adapter size based on the diameter of your filter's hose. The 1/2" hose adapter size fits well for my Eheim 2217.

______________________
C.
Description: American Valve 3/4-in PVC Sch 40 Female In-Line Ball Valve
Item Number: 21482
Quantity: 2

Note: You can exclude these if you don't want to use them. They're used as shutoff valves for easy removal of the filter housing.

______________________
D.
Description: Orbit 6-in Cut-Off Riser (3/4-in x 3/4-in)
Item Number: 194532
Quantity: 3

Note: Only one of these is needed if you exclude the above shutoff valves. These need to be cut if you want to save space in between the necessary components for which they're used. Only one end can be cut, so make sure you cut the correct end. I cut 4 of the adapters off instead of 5 in order to retain a little bit of space once put together. Please view the picture to see the end result.

______________________
E.
Description: LASCO 3/4-in Dia PVC Sch 40 Tee
Item Number: 317762
Quantity: 1

______________________
F.
Description: Watts 3/16-in x 1/4-in Brass Barb Fitting
Item Number: 69301
Quantity: 1

Note: This was a somewhat tight fit within its accompanying female adapter (#90379 - listed directly below), though both pieces come from the same manufacturer and the sizes are correct. The tight fit hasn't been a problem.

______________________
G.
Description: Watts 1/2-in x 1/4-in Brass Pipe Fitting
Item Number: 90379
Quantity: 1

______________________
H.
Description: LASCO 3/4-in Dia x 1/2-in Dia PVC Sch 40 Bushing
Item Number: 51275
Quantity: 1

______________________
I.
Description: Silver-Line Plastics 1/2-in x 2-ft 125-PSI Plastic Coil Pipe
Item Number: 518528
Quantity: 1

Note: This tube needs to be cut and I cut it down to 9". This fits perfectly inside the available attachment within the cover of the filter housing without the need to use any adhesive.

--------------------------------------------
Miscellaneous components (available at Lowes):
______________________
Description: Blue Hawk 43-ft Plumber's Tape
Item Number: 456833
Quantity: 1

Note: Use this on all threads before attaching each component.

______________________
Description: Murray 2-Pack 7/16-in - 29/32-in Dia Stainless Steel Adjustable Clamps
Item Number: 47670
Quantity: 1 (2 per pack)

Note: These clamps are used where the hoses attach to the reactor.
A SUPER helpful post. (That's why I'm quoting it.)

I kept researching and was still unsure of exactly what I needed. I got all these parts, with one change, since the Lowes didn't have the exact model number. (The brass pipe reducer bushing.)

Couple notes - I got the water filter from Lowes. I opened in the store, and there IS an O-ring in it. That's why I got it. It was $22. The one from Home Depot was cheaper, ($13) but wasn't available locally.

The part numbers for the two brass pieces I got are 645658 and 645891, made by BrassCraft. They fit together easily, even with the tape.

ecotanker Great thread! Thanks for all the great tips and info. I read the first 30 or so pages then skipped to the end. I mod my fluidized bed filter a reactor similar to this. The in flowing water goes down a tube and then up through a sand bed. The return water needs to pass through another tube to get back to the tank. Hopefully this work just as well.

philipraposo1982 is 10" housing big enough for a 75g?
04-20-2015 05:55 AM
ikuzo why not add another valve to close the reactor if you want to bypass it completely
04-20-2015 02:32 AM
Immortal1 Yes, with the bypass fully open, water still runs thru the reactor. How much exactly, I don't now. Will have to spend some time figuring out what regulator pressure, what BPS, what bypass valve setting works. Should be fun.

small bubbles helps dissolve quicker imo

if you open the bypass valve water can still run into the reactor right?
