SPS dominated tank: Cal reactor, Kalwassar reactor, 2 part system?

[JLAudio]

Do these reactors pose any benefit that the 2 part system doesnt beyong just the lack of daily attention the 2 part system needs.

As for the kalwassar reactor, could you use this instead of a calcium reactor for an sps tank to maintain cal/alk or should it be in conjunction with a cal reactor.

Please let me know what you have used and your experience

Kalkasser will help raise your PH from the CO2 added to the calcium reactor. In the cal reactor you add a second chamber which in return the CO2 excess burns out more ten with one chamber.

Kalk can be used alone. From my experience, once your have a moderate stock of SPS the Kalk will have a hard time keeping your ALk and Cal in range. You'll need to dose occasionally to bump a parameter back in range. You can the start adding vinegar to your kalk to make a more potent solution. Do a search on Reefcentral for "Kalk and vinegar"

I just got a calcium reactor because dosing a and b was only making my ph go up...

Kalk reactor will give you a high PH (not a bad thing as long as it is <8.50), somewhat stable Ca if your load demand is not high but will not do much for your alkalinity.
I run just a kalk reactor on one of my systems and I need to supplement with SC Reef builder every 3-4 days. It drops about 2 DKH on me during this time frame.

calcium reactors are not really needed.to many problems with ph and algae.i have a 180 loaded with sps use a kalkreactor and b-ionic.ca450 alk10.dose80ml daily.also dose 50ml tech-m mag weekly.low mag will give trouble keeping ca alk.
