Hi,

I'm new to the forum and I'm after some advice.

In my tank I have it filled with about 10cm of water with a small filter. With rocks and driftwood on one side for Crowley (Australian Green Tree Frog) to sit on.
I have to change the water weekly because after a couple of days there is a strange colourful film that forms ontop of the water. It swirls around with the flow of the filter and it slightly slimey.

The water I use is tap water with a couple of drops of water ager that i got from the pet shop.

Has anyone ever experienced this before?

Thanks
