I’d interested in hearing what you “modified” version would be.
Here's a copy and paste from another recent thread where folks were asked what method they'd use if they were starting over. here's what I wrote:
In terms of water chemistry maintenance, I'd maintain calcium and alkalinity with limewater (maybe pH limited to pH 8.55 or less to prevent overdose; probably on dosing timer rather than ATO) and a two part (if needed; maybe also pH limited to pH 8.55 or less). I'd like a continuous alk monitor, and if Mindstream comes on line, I'd monitor ammonia 24/7 and in different system location (main tank, exit from refugium, etc.) for interests sake.
There are some ions I would dose essentially independent of measurement because I don't think measurement is particularly useful for them (e.g., iron because it is typically below detection limits; silicate because it depletes so fast).
There are a bunch of ions that I do not consider important at the levels reefers typically have (e.g., lithium, maybe barium, I'd need to think through this list) and I would make no effort to control those either by export or by dosing.
I would likely experiment on the tank over time to re-verify for myself that my longstanding opinions on certain chemicals are not useful if dosed to maintain natural levels, despite the fact that many reefers do. If they showed a positive effect, I'd rethink dosing them. These include iodide and strontium.
There are a whole bunch of biologically active trace elements that I'd likely measure and dose which I did not in the past, but which also tested low (e.g., molybdenum) and I'd likely dose these to roughly NSW levels. I might experiment on these in a variety of ways (e.g., allowing one to go undosed for a long time and then restart and see if anything apparently changed).
I'd probably do automatic water changes, but again, might also experiment on the amount, from none to a couple of percent a day.
As to other "methods", I'd likely do some or most of these:
Ato
Temperature control (temp controller to kick on heaters or cooling system)
Skimmer
Rodi unit with inline tds
Nutrient export (macroalgae, gfo, organic carbon dosing, GAC, maybe experiment with organic resins like Purigen)
Might try LED lights to save electricity, but I'm not yet convinced I'd like the look
