calcium reactor concept

[hermit]

any experts can help me to understand the working theory of a typical calcium reactor.......

i may like to diy the reactor but till now still dunno how it works lehhhh.........

if i succeed in coming out if the equipment, will the reactor produce excessive calcium and overdose the aquarium .................?

so wat are the general material needed ?

can any diy bro show me some of your calcium reactor ............?

thank you...............

[ah^siao]

i'm interested in knowing how to DIY one calcium reactor also

[sinner]

me too!!! somebody pls teach?

Hi ,Here is my DIY C.A.

Basically it circulate through the calcium media (arogonite or ARM).

1 water inlet from the tank and outlet with a needlvale to has a dripping rate.

And a CO2 input to bring the PH down to 6.8~7.0 so that the media will dissolved

That's cool! how's the cost to make this? Cos I thought of using Eheim 2213 canister to make one

[ah^siao]

where u get to find that transparent tube tingy?????

and how much it cost u? the whole tingy? nice piece of work i would say

[cmswong]

Hi,

The cost :

Acrylic 4 "OD 1 meter $100 (I usead half for C.A and skimmer)

Black arylic base and circular disk made from Yeo Soon plastic in jalan besar at the HDB making ice water box.about $20.

The fitting and union cost about $35~40.All 16mm fitting

Tooling for taping cost about $50 (this can save by change some design)

Calcium media cost $60

Calcium media cost $60

wat kind of media is that ?

[cmswong]

Hi,

It carrib-sea A.R.M. (from friend )or U can use arogonite .

[cmswong]

Hi guys,

I copy the design from geosreef linkHere

After browing many design I found this is easy for DIY.

still got the lobang ??? interested ... u PM me the details if u can/have ...

[ah^siao]

nice piece of work i would say.. where u got that Acrylic 4 "OD 1 meter $100 (I usead half for C.A and skimmer)

from????

Hi ah siao,

The acrylic tube is 10cm by 1cm thick from dama plastic

wat is a needle valve and where to get it.......?

how to put in the co2

where does the co2 come from ?

can show how you come out with the reactor using hand drawn diagrams with some words explanation ?

thank you very much..............

btw is it efficient and will it overdose ?

can coral chip act as the calcium media ?

Before I get into the details of building a calcium carbonate reactor, let us first take a very brief look at the basic principle behind it. The easiest way to view the functioning of the reactor is as a reverse calcification process. The idea is to dissolve a calcareous media in such a manner that it provides both bicarbonates HCO3- (alkalinity) and calcium (Ca++) ions in the same ratio as they are consumed during calcification. Effective dissolution of the calcareous media requires that the solute be at an acidic pH. Because saltwater is usually at a pH of 8.0 and higher, we need some way of reducing the pH in the reactor to aid the dissolution of the media. Carbon dioxide (CO2) is used to help lower the pH in the reactor, and the general reaction form is as follows:

CaCO3 + H2O + CO2 <——> Ca2+ + 2HCO3-

So, the calcium carbonate reactor is basically a device that brings the three ingredients — water, CO2 and calcium carbonate — together in a manner so as to allow efficient production of HCO3- and Ca++ ions. All reactor designs basically follow the same principle, but differ in the techniques to create the circulation loop, the manner in which CO2 is injected, how the water is input to the reactor, and how the effluent is drawn off. We will just stick to the basic principles and look at building your own reactor.

Is there any advantage of building a calcium reactor compare to buying off-the-shelf liquid calcium?

Thanks,
