Thanks Jan,
I cleaned it out yesterday, but withing 12 hours it had tipped over. Do you
not think it's the hair algea? Every time it's tipped over there's been
lots of it around the pump.
A while back the hair algea was very fine (i.e. not solid), but now it's
gone a darker green and is more clumpy and solid. Should I get rid of it?
The tadpoles and the newt seem to like it, but I don't think it's doing the
pond and fish much good in this state.

Cheers,

Steve

I have an all-in-one pump/filter/fountain. Recently it has started

over and on one occasion it rose completely out of the pond! There's lots

I don't know why it's started doing this (it's just a year old). I think
it
might be to do with hair algea getting caught around the vents and perhaps
the pump is sucking the air from the algea?

Any ideas?

Clean it. Sounds like the pump isn't getting enough flow from clogged
pads.
This can make the pump gravitate, knocking oxygen right out of suspension
causing bubbles to get caught in the filter (under the clogged pads). If
it
continues to do this after cleaning, sometimes you just have to put a few
rocks in the box. ;o) ~ jan
