Ph swing ranges

[L/B Block]

Curious to what people have in respects to their daily high/lows and what is considered a “good swing” range?
If late 8.05/8.15.
Tempted to throw some BRS CO2 absorbent media with a Neptune solient valve to lock the PH at 8.25 (or 8.3) and keep it consistent .
Not sure if worth the price of the media and the set up time. Would keeping the PH at a consistent value ph pay off dividends in respects to coral growth (and perhaps some algae reduction)
Curious to hear from others on their ph values and the concept above.

My PH range is 8.25-8.45

You ever see issues with alk/calc dropping?

I'm 7.8 to 8.0 in the 120 gallon.

Mine around 7.9-8.1 cause of carx. I dose kalk in my ATO to maintain my ph

I am about to start my drip this evening based on your notes too

But your tank is new, do you even need to start dosing?

I'm dosing 75 ml a day in my new tank and I keep having to bump it up.

Well I guess I learnt sumthin today

I want to start adding kalk and mg. Might be "new" but was from a pre-cycled up and running system, so I already have a bio load, corals, clam, Anems etc .....

In all fairness the tank is a new set-up, but I had grown out corals for it for almost a year in a frag tank which were then moved over when the tank was ready. So while it's new it has a lot of established corals with needs.

My range is 8.13-8.25 or so, and I’m not aware of any proven benefits from having it more stable.

My frag tank swung between 7.8 (sometimes lower) and 8.5 and never hurt a thing that I could tell. I actually have the PH probe out of that ank now and have for a while. I jusat really don't care.

I'm around 8.0 to 8.2. I only started tracking pH about a year ago for the heck of it since I had a port there on the apex. Never needed it the six years before that on the same system. However, now it's a safeguard for the newly added calcium reactor if it were to fail.

7.8 -> 8.2

What are you trying to grow? Acros?

Article definitely informative. Thanks. His point was keeping it at 7.9 was potentially more damaging than keeping it at a range that crossed 8. However if PH was kept at constant level was kept at...8.25 or so with some CO2 absorption media and a solenoid valve to cap it would that be different?
Might have to jump over to r2r to ask him!

What I gathered from my research is that as long as you keep PH in a good range and it doesn't swing huge - forget about it
