I ended up changing out about 80% of the water and waited about half a day to stock my tank with fish. Out of sheer newbness, I mixed some fish with tiger barbs and quickly learned that tiger barbs are aggressive. So now I have a tiger barb only tank. My PH levels went down to around 7.6 after everything was said and done. The tank has a lot of algae growing, so i recently purchased some flourish excel to dose/treat the algae problem. I'm using less dosage as directed cause I've read bad things about overdosing with excel.
Tiger barbs are pretty awesome little fish btw. They tend to follow me when I'm in front of the tank like they know they will get fed soon. I have 3 juvenile Albino tigers, 3 juvenile Green tigers and 5 regular tiger barbs. oh and a couple ghost shrimp that's been surviving fairly well under my little patch of java moss.
