Thanks George, I also use them to cover the surface to keep our birds,
coons and sun while I am at work.
The filter feeds from the bottom and pumps about 8L or 2 gal /min
so far everything is fine but was just wondering how long till the filter is
working at max capability.
Thanks
Steve

Depends on the size of the pond, but 2 gal/min doesn't seem to be very much. If
your pond is very big, it is possible that your filter will go septic, and start
cranking out foul-smelling hydrogen sulphide. Mine pumps about 1,400
gallon/hour for a 1,200 gallon pond (the container is an old jacuzzi swimming
pool filter with about 40 gallons capacity, half-filled with rounded gravel).
It also has a 5 gal capacity pre-filter. What size is your pond?

Here is a link to my web site that shows my pond:

You can see the pre-filter in the first picture. The main filter is below the
waterfall (which I have since made major modifications to).

I just built a bio filter with veg on top and was wondering how long it
will
take for this bios stuff to grow in the filter?
How long until it is working at 100%?
Can the bio freeze solid or should I sink it?

I used pot scrubbies and cut up election signs (Canadian). The
corrugated
plastic makes good medium with good water flow and surface area. All
crammed
into a 5 gal (imp) plastic flower pot. If I had a digicam I would have
a
pic.
thanks


I have to say it. That is the best use of an election sign I've ever
heard of.
