4 foot could be anywhere from a 33 gallon to a 240 gallon if it's a tall cube. A fluval 205 is rated for up to 40 gallons from what I'm finding. The absence of any nitrates is a bit odd, unless the tank is heavily planted. If those results are from test strips they are horribly inaccurate, get a good liquid test kit.

Mollys like water with a higher pH, as well as harder water. That could be part of the problem. Never trust your water supplier, with any case of ill fish with unknown origin a large water change with double the suggested amount of dechlorinator is the best place to start.

I would also up your temp. 25deg celcius is a little to low for mollies, or so im lead to believe.

How strong in the current from the spray bar? Is it possible the current is to strong for them?
