Ph Down Bottle

Good size, great value and accurate product

Good product and good value for the money.

It killed some fish I used a lower dose than the directions suggested. But keep in mind to lower the ph you must add Something acidic. I guess my fish couldn’t take the acid or ph change . I was told after the fact don’t try to change your pH if it’s not perfect it’s better to be consistently not perfect.Than make a change

Great product. Works well!

I'm in the middle of cycling a tank right now and the water where I live is excessively alkaline - so I added enough drops to bring our 9.0 water down to 7.0. For my tank it did take more than two drops per gallon (I have a 29 gallon tank) and each time I added the 2 drops per gallon I tested with a PH test kit - DO NOT GUESS. In the end I believe I added about 150 drops to get it to 7.0. A few days later I tested the water and it was back up to 8.4 - BUT in the meantime my ammonia, nitrite and nitrate values had changed significantly - so I recommend that you only used it AFTER you've cycled your tank or expect it to wander a bit as your tanks chemistry changes so if you have fish that are very picky about PH- test often and alter accordingly. Luckily most fish aren't that picky so don't get too uptight about it.
