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

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.
