Calcium reactor capacity

Hello all, i am trying to figure out what calcium reactor i should get, and i see that many manufacturers rate their reactors so much differently, is the media capacity really important of a reactor? Would a 2L (0.5 Gallon) of media be enough for a 80g sps heavy tank?

That's roughly 4.5lbs of media. It should be fine. The only thing that happens when you go smaller is you have to change media more often.

Do you have a physical constraint?

Yup. ^

The smallest reactor can handle the largest tank - you just have to change media more.

My only real requirements for CaRx are reverse flow and Ehiem pumps.

What do you mean with "physical constraint"? I you talk about the room I have under my aquarium is a bit small because I have to fit a chiller also in there.

Reverse flow CaRx is the upflow one right?

Yes, are you getting one that size because you cannot fit anything bigger?

Yup, upflow is "reverse". I second the ehiem recirculation pump requirement.

My personal preference is a masterflex feed pump, ehiem recirc, cabon doser or two stage reg, and effluent output on the top of the chambers. I hate this sales tactic of recirculating un-dissolved gas in the reactor to be efficient on CO2. It's a sham IMO

I have arrived, largely through trial and error, with a CaRx (a modified MTC ProCal) that requires refilling every six months or so. Masterflex is an awesome upgrade and circulation pump should be reliable (eheim, iwaki, panworld).

I am into Korallin reactors. They trap undissolved CO2 at the top and I can see when I have too much and can tune them back. When there gets to be too much CO2, the Ehiem pump fills with the CO2 and stops circulating keeping my media from melting - the Ehiem pumps can run dry and not get damaged. There are many other that do the same thing, though.

I can't decide between those two:

1.grotech hcr110 http://www.grotech-aquarientechnik.d...m-Reactor.html

2.tunze 3171 https://www.tunze.com/CY/en/catalogu...=-infoxober013

I like the self primming on tunze, but I like grotech too for the upflow and the eheim pump.

I cant have access to Geo products because i am located in Europe. I wish i had, they look extremely well built.

I'd probably go with the first one. Do you have access to korallin?

One other thing to keep in mind is that the ability for any CaRx to generate minerals is a function of the amount of media (and a few other things). While I cannot say its a linear relationship, when the rubble chamber in mine falls to abut 50% capacity I refill it - otherwise my alk + starts to fall because the 'contribution' from the CaRx has also fallen.

Yes that is absolutely correct and I already have it in mind that's why I am thinking going to a bigger model so I have to replenish it less often!
