Lowering pH

I currently have a tank with a pH around 7.6. This is higher than what is recommended for any of the fish which I have in there. The tap water has about the same pH, is there any way to lower the pH? I don't really have a lot of space for any extra equipment.

Any suggestions?

Can you list the fish that are in the tank now? Most fish can live a healthy life in a PH higher than the recommended ph. A stable ph is better/easier than a fluctuating ph. There may be no reason to lower it.

I currently have 5 sunburst platies and a whiptail. Its a 10 gallon tank with live plants.

That pH will be just fine for them! I'd not recommend messing with the pH for them fish; as more often then not this will cause you up&down swings and that's much worst for their health. So just leave it alone :-)

All the fish you have now, will be fine in your ph. I would leave the ph alone.

Angel beat me!:-)

If you want to lower your PH, by an RO filter from eBay for around $50. Treat RO water with RO right products that add essential minerals to RO water removed while filtering. They, use a special RO PH chemical and adjust the PH to your desire.

Another way is add PH down product but I don't recommend it. It might work temporary but usually it just swings back up which is called the rebound effect. It is a PH roller coaster and puts stress on the fish.

Using RO water method is best choice to lower PH because. I have a discus tank and use this method. An alternative cheaper way is to collect rain water because rain water is mineral free. Just make sure the rain is not polluted. Hope this helps.
