Ca Reactor questions from the un-informed

[medic29]

Hey I have a question?? What would be the issue if one was to get a calcium reactor that was rated for a smaller tank/system? I'm thinking the biggest difference between the reactors is the size of the chambers and the amount of media they can hold. Using this logic I'm thinking that if one had a reactor with a smaller chamber they would just end up having to fill it more often than if the media chamber was larger. Again, I'm very new to calcium reactors and really have limited knowledge in how they work. So....does size really matter??

size it's matter when you use big tanks or heavy bio load . for your 120 gallon tank
size like geo 6/12 will be great i have the same size on my 120 gallon and i was able to keep alk and calc the level i want with 7-9 drop/min co2 and 20 mlg/min from the effluent .
in bigger tank you will need to dreep more co2 and dissolve more media , but those media (the big one) not spend so quick . ifyou have already one and you can't keep the level you can try to drip more co2 and in some case need to change the circulation pump to stronger one.

a larger tank needs more Alk/CA. To get the more alk/ca you need to increase the drip rate or decrease the PH in the reactor. Increasing the drip rate will increase the amount of water going through the reactor. This will deplete your low PH water in the reactor quickly. With a large reactor, the water flowing through it is a small amount relative to the water the reactor holds so the PH can stay low with a quick drip rate. If you have a small reactor and a quick drip rate, the new water coming in will raise the PH quicker. You need a large reactor for a large tank.
