Diy calcium reactor

Well I have been wanting to switch gears and get rid of my dosers and go to a calcium reactor for my 90. I have been looking for a used reactor for some time but even used they don't come cheap. The best I have done so far is one that Antony ( raffle king ) offered it was a good deal but I have been looking for a duel chamber reactor and the one he had was a single.
I love to build things so I went on a mad search for possible reactor parts, I priced out acrilic tubes and WOW are they expensive so I went looking through old stuff and came up with two next reef media reactors. One was in good shape and the other was left outside and cracked due to ice inside (shocker) don't leave acrilic tubes filled with water outside if you like them.
So here's how I built it

I came up with a design compiled from reactors I liked on line and purchased the plumbing parts

Starting with the existing holes on the tops I pluged one on the second chamber fron the inside and put a quick connect for the outflow. On the first chamber I installed a 1/2" 90 deg elbow threaded into the top and then to slip

I then turned to the second chamber again and drilled a hole in the Side down low for the inlet and taped it using my trusty chraftsman tap set

Now for the scary part I drilled the inlet from the mag3 into the first chamber and of corse it wobbled but luckily I was able to get a pretty good glue joint with the weld on 16

Now to the pvc all glued up with two plugs drilled and tapped for the co2 and the inlet water from the sump

And the finish for today with inlet, co2, and outlet hoses.
All that's left is to put in a bubble counter and buy a regulator and with the money I saved I can get a better regulator. :)
Total cost out of pocket $20.00 for used mag3, and $30.00 for fittings and pvc.
Won't count the cost of the media reactors because the were not being used and saved them from there doom

Very nicely done Rob. For a brief second I though about switching...........and then the horror stories flooded my brain.

Well I just got done with my water test and drip ,drip, drip yes 3 leaks very slight but leaks non the less. Seems to be a easy fix some more Teflon on one and some silicone on the other two should do it. Can't be easy can it.

Wow very nice Rob, I love the DIY projects.

What's the benefit of having a calc reactor versus dosing?


When your tank crashes, you have something to blame it on! :eek: :eek: :eek: I'm sorry, but calc reactors still scare me from recent members who have lost everything when their calc reactors malfunctioned.


Stability has nothing to do with it.


I'd venture to say it's size that determines the ease and cost of the two options. If you have a very large system, a calc reactor would (could) be more beneficial. With smaller systems, two part works just fine.....especially if you're a DIY'er. I don't think I spend more than 10 to 15 dollars a year to dose my 90 gallon tank.

There are several reasons why I believe it's the way for me not to say it is for everyone. Here are some: yes I do believe it is a more stable way to add alk and calk to my system not to mention other trace elements that just adding two part does not have in it. What better way to give corals the building blocks that they require then to melt dead coral skeletons back into the water they live in.
I have also been thinking of adding a de nitrifier to my systen and cutting way back on water changes which added those trace elements, so what add another doser to add trace elements or dose them manually as I said not for me.
As for tank crashes I believe most if not all are regulator based and the planted aquarium regulator Has but all corrected this with there electronic regulator.
Can you get a beautiful tank with dosing two part ? Yes
Can you get a beautiful tank with a calcium reactor? Yes
If you stopped changing water every week and just add two part would there be something missing I think yes.
Just like all other Equiptment in this hobby you choose what you feel I the better way to go. Like some people out there who have a sps dominate tank I dose a lot of two part and as my corals grow the amount keeps growing.
Speaking to a fellow reefer who doses 400 ml per day he has to refill his gallon of alk and calk every 9 days as opposed to setting up a reactor and refilling it once a year.
Dosing two part is very cheap I know I make it myself so this has nothing to do with cost.
Just one mans opinion
