Hey Guys,
Before you run off and spend a bunch of money, I am going to give you my take on a DIY Kalk reactor. If you only plan on building one or even two projects it is not going to be worthwile. You are better off to call Ocean Aquatics and buy one of their Kalk reactors. ON top of that, they are 6 inch acrylic instead of 4. I think they caost 150 bucks.
Here is the cost breakdown.
extruded 4" is about 16 bucks a foot.
You will probably want to buy two types of weldon.
Weldon 5 is for extruded and is about 30 bucks.
Weldon 40 (thicker for any problem areas) is another 30 bucks.
Pump is 25 to 35 bucks.
Circle Cutter. 9.99 at Princess Auto but junk or a good one for 25 bucks at canadian tire.
two taps, one for your bolts and one for the water lines 20 bucks.
Plumbing bits about 15 bucks and 20 if you use a union for a fill hole. I recommend this.
Gasket material 5 bucks
So all said and done, you are looking at about 150- 170 bucks for all the parts to build the reactor. If you have some of the tools or parts it will be cheaper.
On top of that you still need to buy or have some flat acrylic to make the base and flange. And I can guarantee that you will have to redo one part of the project if you have not worked with acrylic before.
Hope this helps guys.
If you decide to go ahead, let me know if you have any questions.
Cheers,
Al
