Keeping SPS?

[-=Mach6=-]

I am curious how many people have success keeping sps without a calcium reactor?

Search back a few weeks - there's been at least 2 threads in the last month on this.

For smaller tanks, many don't use a Ca Rx, and IMO, have great success.

I don't.

Most definitely more ...

i've been keeping sps pretty successfully, other than a few STN cases, as those with CR do too, and i only use BIonic daily to keep my Ca and Alk stable. i have no room for a reactor. i don't mind it at all, and it's just 1 less thing u have to worry about, and 1 less thing that can go wrong. u don't need a CR to successfully keep sps.

I keep SPS np but I dose using Randy's three part...

Thanks for the info guys. So each one of you guys dose different chemicals to keep you Ca and alk stabilized?

Seems like most of us dose a 2-part Ca/Alk system - likely very much similar [if not same] compounds. One store bought, one made at home [from non-LFS compounds] ... but same solutions, in essence.

I've used both B-ionic systems and Randy's 2-part [really 3-part, with Magnesium additions] and IMO they're quite similar product [and the same concept, adding Ca from one bottle, Alk/Carbonate from the other to balance these 2 levels in the tank].

While possible, I suppose someone is just using water changes, or just using Kalkwasser too ... just seems that 2-part is most common [other than the most common Ca Rxs]

Just my take on it. Depending on tank size, you could make it quite a while. My 58g after a couple years now slurps up the 2-part ... but while growing out frags, it really didn't cost that much.
