Tank Upgrade PH Question

**jmueller** · 01-18-2011, 11:03 PM

So currently, my fish have been alive and doing well for 1.5 years in a very established 10gallon tank. I test the water regularly just to be sure, but now only now do I have an issue. The problem is that I have high PH straight from the tap, Somewhere near 7.6. In my current established tank (10gallon) the PH reading is about 6.7. In the new tank, which is currently undergoing a seed cycle (using old filter media, gravel, decorations, ext) is giving me a reading of 7.6, because of the new water from the tap.

Is this high differentiation going to be a problem for my fish once I transfer them over to the new tank? Or should my PH come down a little with time?

Im just nervous about this big change in PH for the fish.. Would it be good to introduce some new water to the old tank to raise the overall PH before moving them to the new tank?

Let me know if you have experienced or dealt with a similar issue, or have knowledge that would help me.
Thanks fellas, and ladies.

The fish should be able to adjust to the higher PH. Its better than messing around trying to change it repeatedly. Just make sure you are moving them into pristine conditions and they should be ok. I wouldnt take water ant move it, as you are going ot dilute it with the higher PH water anyways and then it will be lost in weekly water changes anyways...

I would not worry about the PH in your cycling tank until the cycle is done. There's a lot going on during a cycle that effects the PH. In the past I havn't even tested the PH until the cycle was complete and I was going to start to add fish. The PH in your cycling tank can change during the cycle.

As CassieLEO stated it is far better to have a stable PH than a perfect PH, as you have found out by a stable 6.7 in your current tank

If there still a variance between the PHin your current tank, and the new one you are currently cycling once the cycle is done, and you are ready to move the fish, just drip accalmate the fish in a bag of the current tank water. This would be just like when you take them home from your LFS. If you accilmate them to the new water conditions, slowly, allowing them to adjust to the different PH levels, they will adjust fine.

Wild Turkey explained how to accilmate fish a better than I could explain it in the below post.

I hope this will help you
