Tangster,
You have probably mentioned this a number of times. And I have cut and pasted it, but I can't find or remember it....
But you have said something to the effect of: " there is really only three things you need to worry about in order to maintain your tank" Something like if the PH, mag and buffer is right, everything pretty much has to be.... And here is the easiest way to keep them up.
Now, I'm not going off half cocked... I have been reading you post for several years and my tank is probably like you would recommend. I have two tanks (30 and 50 gallons) connected to a 25 gallon sump. The sump had the skimmer on it as well as offset light and macro algaes and a bunch of snails and worms. The smaller of the tanks has NO lighitng with uri bulbs and the larger (which use to be the same lighting) i have just upgraded to MH (250 watt). I have an RO unit that supplies the water and I have extrememly low BIO loads. In the two tanks the only fish are 5 chromis and some shrimp. Everything else is mostly low/medium light corals. I have a lot of button and star polyps and some mushrooms and xenia (weeds:).
Everything is growing great and all appear to be happy. I change a little water (5 gals per week) and I add a little turbo calcium and some reef essentials (kents) OH, and I also use a chemi pure bag in the sump.
I guess that the only thing I would like to change is the chemistry so that I don't change water as much. I don't dose much of anything since I have low bioloads, but I am getting ready to install a new topoff and thought that a kalk doser might also be the ticket, then I remembered your post on what really matters. And I thought I might ask you to repeat it (or some such there of).
I keep thinking epson salts, pickling lime, etc....
