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.
