H&S 90 Calcium Reactor first thoughts.

Thanks to an AWESOME Friend, I made a trade, and we both got what we needed . That said, this post will be about the H&S 90 Calcium Reactor I just received. The H&S 90 Calcium reactor is rated for a 100 Gallon tank, which should fit my tank quite well at a combined size of 95 Gallons. The system consists of a 4′ long 75 Gallon Acryllic tank, and a 14 Gallon Biocube, modded to allow for inlets and returns from the shared sump. The Calcium and Alkalinity requirements are quite low currently, so we’ll get to see how this reactor does with the growth of the tank, having started out from a small load. Since this was a freebie(in relative terms) to me, I had to supply a few parts of my own, that were missing or not included with the original reactor. There are a few accessories that help quite a bit in running and maintaining a calcium reactor:

The reactor feels solid, and is built well. It came very well recomended, and the ease of use is very pleasing. If anything it’s more accomodating to a beginning user, as there are few things that can go wrong. The reactor features a built in bubble counter, which as can be seen in the picture to the left is mounted higher up on the side, making it easily viewable.

Effluent is fed off of the top of the reactor, and the provided valve is makes for easy control of the drip rate. The only minor gripe I had was that there is no re-circulation of co2 built in, but in this configuration, would be hard to do.
The reactor also features a built in pH probe inlet, which, when not in use, seals well. I’ve opted to run a Milwaukee SMS122, and the probe installation was very simple, and made setting up the reactor a breeze.

The Reactor has a twist lock top which is very sturdy, and makes mainenance and resupply of ARM on the reactor very simple. The base is also very sturdy, consisting of an upside down T, which the pump of the Aquabee 500 pump mounts to. Once set up and running, the system seems quite quiet and matches the hum of the rest of the pumps in my tank’s cabinet.

The only reactor I had before this was very hard to work with, and did not have the probe slot, which I think, besides the sturdy build to be it’s best point.
