tonight i went to adjust the ph in my tank again, at the moment it's empty, i hope to get a fish next week.
after putting 3 drops of liquid in my 10 gallon tank, i realized that i was using the ph indicator solution instead of the ph up solution.
did i just ruin the entire tank of water? or will it filter out? i feel so stupid, i should've been paying closer attention. i cannot believe i did that.
do i have to replace it all again?

I doubt 3 drops of indicator will screw anything up, new carbon would probably filter out the chemicals. To be safe (if your tank isn't cycled), you might consider changing out all the water anyway.

Do a partial water change, about 30% or so, and that should get rid of it. You may want to rethink using those pH up and down products. They can end up being too stressful to the fish. Its much better for them to just have one steady pH even if it is high. My tank stays at 8.2 which is pretty high but my fish have adjusted to it and it would only stress them to keep changing it.

oh. ok...i hadn't thought about it that way. there aren't any fish in it yet, so i was trying to get it to a level ph before i bought them. i'm not sure what the water was to begin with though, i don't remember. the filter cartridge is new, so i'll just try the partial water change, and wait a few days for it all to filter i guess.
