I had a 10g that had been set up for a few months & had cloudy water, found out i wasn't vacuuming well enough. When you say water parameters are normal, exactly what is normal? Are you using test strips or a liquid test kit? Strips are not typically accurate, just an FYI.
I didn't use a scrubber to clean the walls when I first got the tank - just kind of rubbed the walls after I soaked the tank in hot water over night - of course I rinsed a few times afterwards to make sure the tank was really clean.
When doing water changes I do sometimes use a scrubber to clean scrub the tank walls but I don't know how often I should do this - does it affect the water parameters if I do this every time I do a water change? (I do 50% twice a week)
The tank's been set up for about 2 months now. Is that still in the time frame that the algae/bacteria will bloom?
I believe I'm doing a good vacuuming with my water changes - I make sure I get the corners and under the decorations too..
I use API's freshwater liquid testing kit - normal according to one of the stickies on the forum...although the pH of the water is slightly high at 7.4 and no matter how many times I change the water, my ammonia levels are 0.25ppm
