As I don't even have a cursory understanding of the subject matter it is very difficult for me to sift through what I'm being advised.

What is most noteworthy for me is that they guy I'd be buying the dosing system from is advising me not to. But, with the apocalyptic predictions that have been implanted in my head running around in there . . . well . . . I just really need to get a grip on the chemistry to be able to decide for myself what approach I need to take.
ok, there's basically cheap salt like instant ocean $ 30-$40 for 160 gal pail, that has the bare minimum of trace elements and calc and mag, so you will have to add more via dosing

The better salt like DD H20 or Zeovit Reefer's Best at double the price that contain all the necessary trace elements and additives. Your choice.

I personally use DD H20 and don't really dose anymore. Just a little A/B mix by 2 Little Fishies when I remember to do it. But you've got to do the water changes regimentally if you don't dose.

I use the Instant Ocean Reef Crystals.

According to this (http://www.rudyv.be/Aquarium/sels.pdf) it looks okay. Not the best, but not the worst, either. That document could be quite old, so it is possible that values have changed since it was published.

But of course, not being totally sure of what affects what, the document isn't a huge amount of use to me.

water changes should be plenty for soft/LPS, sps would require daily dosing (my tank would deplete to half its alk each day if i didn't have a 2 part doser setup)

That article and many others like it will give you an exceptional understanding of reef aquarium chemistry. Like you, I'm not a big fan of the subject either, but after reading a lot of Randy's work on ReefKeeping.com I feel pretty confident these days. Search the archives on that site and on advancedaquarist.com for more from him.

Randy's articles are best and links can be found in the archives at:

From there, you can click on links like:

shouldnt be an apocalypse if you dont dose.....I have a 110g display that is fairly SPS rich and I havnt dossed or even tested a thing in two years......just regular water changes with H2Ocean.......that being said, Im not getting huge growth out of my SPS, but colors are good and thats all that really matters to me....

While I agree that having an understanding of the relationship between the different parameters we test for, I belivestability far outweighs ahving the number bang on. My alk has been as low as 3 and 4 for the longest time. Fearing an apocalypse of my own, I starting raising it slowly. Once I finally had my ALK up to 8, everything starting to burn, bleach and generally show me they were unhappy. So, I let it get back down to 4 or 5 and everything is happy again. I believe it is the large swings in parameters that create a problem.

I'm a numbers geek. I did develop an algebraic equation to help me adjust a single parameter through water changes.

It seems to work.

Uh, you might be over thinking the whole thing
