I have just set up my 150G, seasoned the water and took PH (7.0). Next day I got a couple small severums to cycle the tank. After about 4 hours fish began looking pretty stressed, so I took another PH reading, this time its 7.5 ish. Ammonia still 0 naturally. What would cause the PH to rise so rapidly? Should I do something about it, or let it take its course? Filter is DIY wet/dry sump. I am certain I used the correct type of scrubbies. The tank does have a faint odor in the water, smells a little like the vinyl tubbing. Should I have let water run though the new tubbibg longer before adding fish?
Thanks in advance
