Filters Off..

[PaulEbs]

Inside my community tank, which is 40 gallons, there are 4 seperate internal filters.

2 of these filters are for breaking the surface of the water, which I turn off at night. I am just wondering, as I have the other 2 filters running constantly, does it matter that these 2 'surface breakers' are off during the night?

They are approximatly off for 9 hours, 12-9AM. The other 2 constantly run. Is this a problem?

All the water stats have shown perfect results, any comments would be great.

in my opinion as long as the water stats dont change there is no problem. the amount of oxygen might change, but that should be confirmed through a o2 test kit or a co2 test kit.
