hey great job!! i am thinking of DIY'ing a single chamber square one for my buddy since i just got my new tap sets was wondering what you used for the gasket between your flanges???

Lunch,
Neoprene. Cut to shape. Works wonders. That is pretty much what I use for any gasket I need to make. mmm Tap set.... lol

DJ88,
I started my copy of your fabulous reactor. I was wondering exactly what type of PVC fittings you used between the pump and the chambers. How did you attach the fittings to the chambers to assure good strong leak-free joints? Mike

Mike,
Where the PVC went through the bottom pieces I tapped them and used MPT fittings to thread through them till the fitting was tight against teh acrylic. Then put a FPT over the open thread which the spray bar is attached to on the outlet side. THe intake side for the pump is a FPTxFPT 1/2" 90 degree elbow with a 1/2" nipple through the acrylic. To ensure a seal I ran a bead of Weld on around the PVC. Where the PVC goes into the pump is a bit more complicated. lol There is a threaded 90 in there. Into the 90 I put a 1/2" threaded barb. Onto this threaded barb I wrapped a rubber sealant tape around the barb. This taped end was threaded into a 1/2" FPTx 3/4" slipxFPT Sched 80 fitting. This was then slid into a 3/4" slipxslip fitting which has two 1/4" tapped holes for the CO2 intake/water in and the recirculation loop. Into the other side of the slipxwslip fitting goes a second 1/2"FPTx3/4" slip fitting into which a 1/2" nipple goes in. Attched to that is a coupling shich is threaded into the pump. Confusing huh? here's a picture. I can't really explain it any better. Really. lol Wht that whole last bit does is creates a venturi. A small one. But enough to ensure that there is suction going into the pump. This pulls water in from the recirc loop and also assists with the intake of water and CO2 to a small degree I think.

While I was waiting for your reply, I stopped by the local Ace Hardware. I picked up a couple of ½“ bulkhead fittings that will work nicely.
I see a narrow-tubed re-circulating loop from the top of the reactor to one of the venturi fittings. I’m guessing this how you recycle excess CO2 from the top of the chamber, this is clever – I think I’ll do that as well. You also use a 2nd venturi to draw water in from the tank. Is this venturi suction alone strong enough or do you also use a Minijet or something to send water to the reactor? One last question (maybe). Your design includes a lot of fittings and connectors. Is there any salt creep at these interfaces? Should I put a dab of silicone sealer into any of these threaded connections or is the Teflon tape adequate?

Oh yeah.. one other thing. I am making a slight change to the recirc loop up top. What I plan on doing is enlagring the hole where the fitting then placing a piece of acrylic over top of this to create a small hollow place where the CO2 will collect. That way the intake for the recirc loop is the highest point on the reactor. Then no CO2 at all will collect up on the top.

Guys,
If I can cram in some time in between studying for transform calculus tests and doing several hours of electronics and programming homework nightly I'll do them up in Viso. Where its all square shouldn't be too hard. Thanks for the interest.

How many hours do you think yo uput into the construction?

Darren, looks real nice but where did you manage to find the 1/4" fittings? I've looked everywhere. No luck.

Great design Darren
Can't wait for the plans Quick ? you said your running it on a 30gal tank. What was it designed for or does the size of tank matter. The reson I'm asking is I will build one(for my 150) which doesn't seem to be hard at all. Only how do you know what the reactor can handle( my theory is the amount of media). Thanks Brian P.s. Stop reading the board and hit the books lol |

hi DJ88,
I'm still a little confused about the workings of a calcium reactor. Effluent means "processed" water out to tank right? Could you please explain the vinyl tubings in your design. Appreciate it! |

thanx for the reply.
which of the vinyl tube is for for injecting water into the reactor from the tank. Is it the one at the top? |

how does the effluent flow back to tank? gravity?
why do we need a pump from tank to push water to the reactor if the venturi should be enough? thanx for the help. |

hey DJ I have a question for you.
You were saying b4 about the low bubble rate of CO2 you were using but I did not see a bubble counter in any of your pictures... ??? Thanks, Mark |

Hey can you post some close ups of the bottom of the reactor. I would like to see that a little better.
Also, how did you fabricate the small diameter vertical tube in the "downflow" side of the chamber? A good pic of that would be great too. Did you say there was a visio or jpg of the design? Thanks alot for the cool reactor, I may give it a try. |
