This is when you use an air pump with stone (I use a wooden one), typically in the evening/ overnight hours. This is placed near your return pump, which helps to further break up the already micro/ small bubbles and dispurse into your Display Tank. It is said, this helps to clean and stabilize your tank. Here https://reefstable.com/blog/micro-bubble-scrubbing-reef-tank/ is a link with more info.
Morpheosz, I don't get any salt creep, however I'm using a wooden air stone to achieve a very micro bubble prior to the return pulling the bubbles in. Also, I don't have the stone/diffuser under the return, so it only pulls the tiny micro bubbles into the pump. I use Lee's, link below.
It all depends on your goals.
Same holds true for stabilizing alk extensively, etc.
Bit more than a slight increase I would say... 7.89 before changing my media, then 8.3+ with dips into the high 8.2's. I will keep a watchful eye on things and report back after keeping pH above the 8 marker instead of just letting it ride like previous. I could give you much better info, however I was on the recieving end of TMPro salt crushing 90% of my tank/SPS heavy in the last year. I'm just now on the recovery, upswing.
Never once noticed any smell or residual or other negative effects so I sent a email off to TM along with pictures of the bucket. Not sure if there are any lot numbers on there they can use for their investigation. Also let them know how I use it, the approximate gallons made per water change, container, etc.
I would say that it bears remembering that the pH scale is logarithmic, so what looks like a small increase (in my case from 7.9 to 8.2 for daytime highs) is a bigger increase than it appears and since I've moved it up by that 0.3 average, the daily alkalinity / calcium uptake has increased significantly (which in theory correlates to something in the tank growing more)
What does that even mean as there is a lot more going on with the system than just the pH number. Hope your Friday is off to a good start!
Of course. The "in theory" part is the crux of the problem
But as I said - this is a "me" issue, not a "you"
I've been measuring my alkalinity daily since my tank started and I can see a clear correlation between higher pH days (e.g. when it hit's 8.23) vs lower pH days (e.g. it only hits 8.17) and on the higher days, my alk reading is quite a bit lower the next day. So that part is not theory in my personal experience
Also, if you haven't come across this yet, the BRS folks ran an experiment that went a ways towards taking this beyond hypothesis or theory...
