Calcium reactor help

[sphelps]

Years back I switched from a Ca reactor to dosing for all the advantages relating to independent and better control of what is added and when. I later concluded that for me these advantages are actually disadvantages. I switched back to a Ca reactor, with a PH controller it's set and forget for me. I adjust output to a slow drip and set the internal pH to maintain alk levels in the tank. You can increase flow rate as well to boost the output as you can only set the pH so low but IMO if you end up needing to do that the reactor is probably under sized. For some extra Ca and Alk you can add a Kalk reactor inline with the ATO which tends to work nicely with a Ca reactor as it will boost your pH.

In terms of clogging, I don't ever seem to have any issues.

it's set and forget with ph controller. Every 6 month when you refill the media, calibrate the probe at the same time, and that's about it.

For the initial dial in, it's very easy when you have a ph controller. You will just have to test few time at the begining to make sure the drip rate is able to keep up with amount consuming by corals.

It is alot cheaper to run a Ca reactor in the long run in the big system.

I am happy with my rx6duo, I know apexifd is selling his rx4. Calcium reactors are very basic in design, few key point you want to look for in a unit will be upflow design, ph probe, easy access for refilling the media. Those are the 3 main reasons that brought me to the vertex line. I love how the line fittings are all john guesst and the top is a screw off design instead of thumb screw which can be rather annoying. I do use a feed pump to eliminate clogging, it does raise the back pressure a bit but that why the vertex comes with silicone orings.
