Hello Joe,
Just wanted to say that I have always enjoyed following your tanks in the past, and this newest reboot is certainly no exception. It's kind of funny, I haven't really been on Reefcentral much over the past year, probably because I haven't really enjoyed the hobby much as the result of dealing with a lot of problems with my current 150 gallon tank, in part relating to some big nutrient imbalances, carbon dosing, weird algae blooms, mass coral death, tank covered in dinos and cyano, etc. Anyway, about a month ago I decided that instead of carbon dosing via Zeovit, or biopellets, or whatever, I was going to step back to something similar to how I set up my first tank about 15 years ago: good quality live rock, sand, big skimmer, and macro algae for nutrient processing. With this plan in mind, I hop back on Reefcentral and discover that there are several reefkeepers that seem to be doing something similar! Moving forward with the theory that it is better to model your approach based on how a few successful reefkeepers are running their tanks, as opposed to borrowing bits and pieces from how many are doing it, and throwing it all together, your tank seems to be closely inline to what I am trying to do.
Anyway, I wanted to pick your brain about using macro algae, and specifically your ARID reactor. After running this setup for a while, would you still recommend going with this reactor over a more traditional macro algae refugium? In my current tank, I have had high NO3 (like 40 "“ 50 ppm) and nearly zero PO4 for about two years. Nothing that I do seems to make any difference: dosing PO4 to correct the imbalance, lots of water changes, zeovit, Red Sea NOPOX, Ecobak pellets, etc. I am going to break my tank down over the weekend, and start over using Tampa Bay Saltwater live rock and sand (and deal with the associated hitchhikers), but my main concern is NOT using any sort of carbon dosing going forward. With this in mind, I could either set up a separate maybe 50 gallon refugium with a deep sand bed and macro algae, and plumb it into the tank, or go with a Pax Bellum ARID reactor. The traditional refugium does have the advantage of being a place to put my live rock hitchhikers, etc, but at the end of the day, I just really, really don't want to have a bunch of nutrient issues with this new tank reboot.
Again, love your tank, and hope I can get mine to look half as good as yours someday. Thanks for your time!
