We have all seen the ubiquitous so called “reef parameters” so I’m not asking for a rehash…. What I’m asking is what numbers are critical and/or fatal and why? Who or what says so? I’ve only heard repeat parroting of the same numbers over and over by “influencers” or some cited reference to a marine biologist study…..I’d like to hear from actual accredited marine biologist that are also aquarist? (and/or anyone really) What say you?
-where and when did the 79F come from and is temperature stability even that important? and if so for what? growth? I know that supposedly it’s the avg Reef temp, but what is the actual cold/heat range and why didn’t the “influencers” pick the actual middle range? say 76F for example
- if the Sun is 5000K why use 10K or 20k? if the logic is duplication of natural params doesn’t red light penetrate to aquarium depths anyway? I realize we can’t realistically overdrive white bulbs without wasting juice in lieu of zoozanthelle loving blue wavelengths, or can we? Our tanks are not 20ft deep or has it been proven ALL red wavelengths are totally useless to the coral itself at any depth?
And then there is Alkalinity, Calcium and Mg ….
I was inspired by this
Thread
..if our logic with light and temperature is to play it “safe” or optimize biological resources seem many reefers are running lower alkalinity (7dkh or lower) …. perhaps disproving the need for high alkalinity and the related chemistry
-I haven’t found any consensus data on how wide the actual tolerances are for Alkalinity against NSW, just testimonials correlating tip burn to high alk and low nutrients. Not doubting it, but like “UAP’s” all we have is testimonials from credible witnesses and no hard evidence (numbers vs numbers) …
It’s just that I’m not sure the sample size is large enough or well organized enough for any firm conclusions….
OTOH….
That said we also have an assortment of “influencers” proposing params higher than NSW as safe (8.0 >) and perhaps without its own set of unique problems. So what is the dKH fatality tolerance or range of coral, and what factors allow survivability outside of NSW params? …. I think this POST raises that as a legit question
I wish This thread materialized a lil better and got more post

please contribute If you have a opinion on Alkalinity/Calcium/ et tolerances/params; what factors govern your decision? your risk assessment? what is your implementation & delivery strategy to reach, maintain and stabilize those params? How much variance or tolerance do you believe is biologically optimal for corals? (how much alk or calcium swing is tolerated before stress)
