My tap water is 7.6 - 7.8 I put it in my tank and the pH quickly goes beyond the testing kit (above 8.8)
This is my 5th day of cycling first tank. What should I do?

If I sit back and do nothing it may harm the plants. Their leaves seem to shrivel up under these conditions (fold like an accordian)

Can you give us a little more info about your set up ?

The tank size , filtration. Anything else besides plants in the tank ?

I am a little confused , since I have heard about the pH dropping , but have not heard about the pH rising in a matter of minutes or hours.

What did you put in there as substrate ? Any crushed corral ? Or anything else that would make the pH rise ?

What is the pH in the tank after the water has been in there for a day or two ?

I am a little out of my element here , but we have some great people that will come along and help.

If for now you could answer my questions so we have some more info ,that would be great.

I will most certainly follow this thread , since I have the feeling I am about to learn something new.

Welcome to OFL !!! :)

as you stated you're still cycling .. when you put in the water .. are you adding prime? are you adding ammonia? how are you cycling your tank?

I guess adding Ammonia could alter the pH , but since there are plants in the tank already I thought that there may be fish in there as well.

I'm afraid I haven't got an absolute answer to why your pH is going up so quickly. However, it is not unusual for pH levels to fluctuate a lot during the cycling process. Plants are really the last thing you should be worrying about, it's a fish that will suffer if things are not done properly. The problem with a very high pH is it makes ammonia that much more toxic so you will have to carry out water changes when the ammonia rises above .25. Unfortunately I think the cycling will probably take quite a long time for you.

I may not always be right, but I am always the BOSS :-)

You're not going to believe this, pH returned to normal somehow. It was off the scale just 24 hours ago. It's like something in the tank ate the acids then spit them back out 24 hours later. Its amazing how our cycling tanks seem to defy science.
Your answers and support meant alot to me. You really are a great community of people.

Still wondering if there are any fish in that tank...?

No fish in the tank yet. Thank goodness. They would umm, all be dead lol.

The guide on fishless cycling I read ON THIS WEBSITE was fantastic and convinced me it was the best thing for the fish.

But when the tank finishes cycling in about 15 days, and the pH continues going off the scale during every PWC, I dont know how Im going to take care of the fish for the 24 hours it takes my pH to go down. I did my own research and CO2 is converted into carbonic acid, one possible explanation for a pH reading going down. I have soft water which allows the pH to shift easily, but the pH going up instead of crashing is something I cannot explain YET.
,
Hopefully I wont have to explain it, hopefully cycling will solve everything, but I'm going to try letting the water I'm going to use for a PWC sit for a full 24 hours and see it that helps.

I agree. The fact that it is going up instead of going down has me puzzled as well. But if you are using Ammonia to cycle your tank that could be causing it.
