Getting a 240 have a calcium question

[jq1177]

Hi I asked this in the large tanks forum but nobody answered so I thought I'd try here. I am getting a 240gal tank in three weeks. I plan on having about four or five SPS and then mostly LPS and Zoanthids. I'm going to have my top off go through a kalk reactor. Do you think the kalk will be enough or will I need a calcium reactor? Thanks Tom.

You might consider a 2-part solution so you can really dial in your parameters. You can get it in bulk for not too much, and you won't have to mess with a reactor.

with just several sps, two part solution is probably easier. And cheaper.

i dont have that big of a tank, but i would think the kalk top off would be fine. its easier then having to dose all the time..
