Has anyone ever bought live rock from Petsolutions.com? If so how was it? Also on a refractometer, are the ones that are around $30 good enough to do the job? I seen several on EBAY, wanting to start my QT with hyposalinity and and need more than my swingarm hydrometer. My last question is my LFS keeps trying to talk me into a ReeFlo Dart or Snapper pump. I was wondering if there is a cheaper return pump that I could use that would give me the GPH just to get started and then go for one of the more expensive ones, Between the skimmer and getting the sump and the LR things are adding up quick! Thanks for any feedback
