Sudden increase in pH - Ugh

As soon as one issue is resolved, here comes another. I tested my parameters two days ago and everything was great. Tonight I noticed a dead fry and two others that looked like they were struggling so I tested the water. My pH suddently went from 8.0 to 9.0. I did a partial water change (about 10%) but it didn't help since the pH in my tap water is 9.0. I am assuming I need to go get some peet for the filter? Go get some spring water from the store? Ugh....

I'm not sure if I am here just to vent or if I am here for guidance, but I do not want to lose my fry! :(

It is getting hard to keep a stash of dechlorinated water since I'm also doing such frequent water changes in the 47 gallon that is cycling.

Hi Lisa,

Please ask your water company for reasons why the pH manage to go that steep. It is very high, in my opinion, for several fish, not to mention those from soft acidic waters. Could you please include the results for hardness levels? The amount of peat really varies depending on your hardness levels.

I have read on here that the pH levels in tap water can change due to the recent amount of rain. Not sure if that is true, but I will contact the water co and find out. I haven't had a problem with the pH until now.

The test results earlier showed the GH as 8 and the KH as 5. From my understanding, both should be in the normal range. Thanks for the reply!

Try to get a bucket of tapwater and filter with peat. See if you can make any difference with the pH.

Leave another bucket of water overnight and test in the morning to see the pH.

I went to my LFS looking for some sort of peat filter and they said they strongly oppose changing the pH. I checked the pH in the 47-gallon (same tap water used) and it is still at the 8.0 level. So I guess the hardness in it is leveling the pH? Any ideas what could be causing the increase in pH in the 20-gallon? We have not added any new fish for a while, but we did add a Mystery Snail and frog about a week ago. Wonder if that is it?

I am on the hunt for some sort of peat to filter the water. Hopefully tonight I'll get that taken care of. Woke up to one dead fry - he looked undeveloped when he was born so I assume he is just weak, but I do not want to risk any others.

Geez! 9.0 tap water!? That's crazy, it's even pushing it for African Cichlids. I'd seriously complain to your water company.

I was so focused on trying to lower the pH that I forgot to call the water company. The pH in the 47-gallon is still at 8.0 and I did another water change on that today, but the 20-gallon remains at 9.0. All of the fish seem fine so far, but I don't want that to relax me.

Does anybody know if the mystery snail and frog I added could have something to do with the change in the pH so suddenly? It was over a week ago that we purchased them (snail for my son, frog for my daughter - lol).
