CA Reactor or Dosing

[Lampshade]

I've done a full "budget" SPS reef tank. Look for used calcium reactors, lots of people switching to fancy new dosing systems. I picked up mine for $200 and will provide more than enough for any growth. Costs me about $50 a year refilling my CO2 and buying a gallon jug of ARM media that lasts a year and a half. The cost for Dosing would be much higher yearly. Lots of ways to save money on a reef tank, but sometimes the fancy new start-up systems are actually worth the money to save hassle.

I've been running a Ca Reactor since 2006. My current PM 622 (old down flow style) was purchased used and has worked very well for me since 2007. The only issue I've had is with the CO2 Regulator. I tried a Milwaukee and then an Aquariumplants.com unit, both have given me more trouble than they should have. I'm not sure what the best on the market is right now but its well worth your while to not cheep out there.

Total system volume is 240gal.
