Ph really high?????

[TheLittleMermaid]

Dont know why but all of a sudden my nano spiked on it's ph levels. Why would it do it and what can I do to help it. I am very consistent on water changes and cleanings. I just have some inverts in the 2.5 gallon nano with some mushrooms and polyps. I've added some iodine occasionally and also diluted color boost. I tested my water it's low ph, I also tested the diluted color boost mix and it's ph is also low. Please help I don't want to lose this tank it's amazing!

How about some actual numbers?

My guess (and just a guess) is that it's coming from the "color boost" you're adding. Not sure exactly what it is, but more than likely you don't need it. For sure don't dose iodine in a tank that small, unless you're testing for it.
