High Tank Water Ph.

[sparky_555]

I've tested my tank water's Ph and its arount 8.5 - 9. But my tap water is around 7.5. is this ok or is there a way i can reduce it?
All i put into my tank water is dechlorinator, its got the standard juwel filter still in use.

Thanks

Are you cycling your tank for the first time? If so this may help

pH tends to go all over the place when your cycling, you can tell from testing ammonia, nitrite and nitrate if the cycle is still going ok. if it is then you've no cause to worry over your pH just yet. wait until your cycle has finished and you've done your big water change, it'll drop back down to roughly the level of your tap water and should pretty much stay there with regular weekly maintenance.

If not and your tank IS already cycled follow this link.

What kind of substrate are you using and do you have any rocks or other decorations in the tank. Certain substrates like crushed coral or aragonite sand will raise your pH. And certain types of rocks, like limestone, will do the same. If you have rocks, take them out and do the vinegar test. Put a few drops of vinegar on them. If they fizz, then they will raise your pH.

You beat me to it!
Totally agree and you could also try adding some bogwood as this will help lower your PH.

Only problem with the bogwood though is that if there is something like limestone or one of the substrates mentioned, the KH of the water would most likely be so high that the bogwood would have a very minimal effect. Peat in the filtermay work better but it too would only have a slight effect.

Sorry Rdd, didn't think to mention that...
We removed all the stone in our tank and just had bogwood, which thankfully did the trick for us.
