Calcium reactor size?

[da5speed]

Im looking at a Korallin Calcium Reactor C1502 rated for 400 gallons Woundering if its enough to power my new system that ill be putting up in the fall. 120 Display tank, 75 gal sump, 30 gal fuge, with a 70 gal frag/grow out tank linked in. So just under 300 gallons. 99% SPS tank

they all do the same thing at about the same pace...you'll just see a faster decline of media in a smaller reactor.

I recommend a larger reactor. My tank was 50+% DENSE growing SPS and ran through that reactor's media in about 3-4 months, with less then half the volume of water.
I don't know if you already have a ton of SPS colonies or will be starting with frags, if from frags, you will take a while to absorb calcium/alk at the rate I was going at.

Based on the pic I see in your profile, you have a lot less SPS then I had in my tank.

never ran the reactor. I know its hard to say but would it last me 1 month before needing to be changed out? less more? just trying to get away from the 2 part

heres a pic before i got 25 new 2-3 inch frags in.

are you using bionic 2 part? if so, how much do you dose per day?
I can give you a better estimate based on that

I was using bionic them my LFS ran out so im using the kent 2 part. I doing 30 ml a of each a day which is less then the amount i need. Cause my alk drop so much a day I add a 1.0 tsp or 1.5 tsp.baking soda to maintain 10-11 dkh, my cal is usually between 400-430. and ph is 8.5.

You should only dose what you need to which is reflected by your daily tests.

at about 30ml/day of each of the 2 part, I would say the reactor would last you 9 months more or less before you need to refill the media (I refill when its about 2/3 used)
