What have I done!

[Emma01]

I’ve dosed today.
After w/c my tank was reading at 7.0 dkh, 6.9 pre change.
I’ve dosed with an intention of keeping it at around 7.5dkh. I’ve checked few hours after dosing and it’s at 8.0dkh..... is this too much of a jump!!??? I’ve got SPS corals/mixed reef.
Ph has also gone up from 8.2-8.5.
Can someone please help answer this for me.


Thanks
Emma

You should be good from 7-8, if it was 7-10 then you may have some issues. I’d just let it adjust back down and don’t over think it to much.

Ph doesnt have a major impact, just let it be and stop chasing a magic number. Best thing you can do for ph is don't even test for it...

Thanks everyone.
I’ve fallen into the ‘idea numbers’ trap. Sorry.
I shall just let it drop down itself over the next week or so.
Thanks xx

7-8 dkh isn't a big deal but a quick PH jump could be stressful on your inhabitants. I don't suggest dosing unless you truly know the consumption of the elements on a daily basis. I suggest testing same time each day for one week and see how much your tank is consuming and then conduct educated dosing.

If you're not squeemish, you can just blow into the air intake tube of your skimmer. I was at 8.6 ph on 70g of water volume after a mild Kalk OD. About 20 deep exhales into the skimmer and I was back to 8.3. A little gross, but easier than dosing.

Whilst the skimmer is on or off?

while it's on.

People always talk about getting higher ph by getting fresh air into the house by running your skimmer air intake outside or opening windows (not as much human and dog breath). The reverse is also true. Our breath is laden with carbon dioxide an it quickly lowers ph.

I’m about to give it a go. Roughly how long does it take to see a drop?

Changed your mind in an hour? My vote would be to not worry about the pH, it will come down when it comes down.

I forget how much water volume you have. I'd give it ten deep breaths and test. Then go from there. It took me 20 breaths on a 60g tank.

Maybe the people who say "don't worry about ph" are right and I'm stupid (good chance ), but it worked, and so long as you don't overdo it, there can be no harm.

8.5 pH won't harm anything in your tank, and a 1 dKh jump shouldn't affect anything in your tank either. Just be sure to watch your dosing next time.

The pH will rapidly go up - and then down after adding alkalinity (depending on what you used). What alkalinity are you dosing? What alkalinity test kit are you using. I wouldn't worry about any of the numbers you're looking at - and you probably shouldn't even be testing until hours after dosing.

And if a picture of you doing it surfaces, you will have a lot of explaining to do if you ever run for public office.

It does - but - first the video talks about 'carbon monoxide' - and its really 'carbon dioxide' - which makes me wonder lol.. Secondly - it rapidly reverses itself (i.e. if we can raise the pH by adding fresh air - then when the 'blowing' stops - the pH will increase back to wherever it was. )

All I can say is that it really does work. Human breath has something on the order of 10x the C02 of ambient air, and we all know C02 lowers PH.
Whether it's worth stressing over PH, you all have been doing this longer than me, so I'll sit that debate out. I do like having the ability to correct a spike in a parameter I have accidentally caused though. Even if a ph of 8.6 is "no big deal," at least I know I've dealt with it AND if I see negative impacts on the tank, I can have greater certainty that it was the DKH swing (or whatever other possible variable) it was, because I have controlled for PH.

On a lighter note, my wife did catch me on my knees, head under tank, blowing into the skimmer.. lol. Thankfully, she didn't have her phone handy

HI - yes - I agree with you - it works - for a short time. then - the CO2 re-calibrates to the value when you aren't breathing into it. If that weren't the case - then decreasing the CO2 of the air outside the tank (the skimmer) by opening windows would not raise the pH. When you stop breathing into the water - its the same as 'opening the windows'.

Agreed.. I don't put it out there as a solution to fixing chronically out-of-range ph. The OP was worried about a temporary spike in PH due to a slight overdose trying to correct up alkalinity. I'm thinking the "felatio" (c) method might correct for a one-time overdose? I imagine a lot would depend on what was dosed to increase alkalinity. I use Kalk, so I tend to think in those terms. It more or less absorbs CO2 when added. The thought would be to replace what was lost during the OD and a return to equilibrium?
