6 Meters is the max lift for that pump. You won't see much
flow besides a trickle, on your 6M high waterfall.

Hi all

I'm new to group and have a few questions about pumps and filters.

I will be using a clarke hippo 2 pump (which I have used before, cheap
and
cheerful) on my 6 meter high waterfall. This pump has a max flow rate of
85
L/Min. With this in mind I was looking to match the pump with a Hozelock
Bioforce 9000 UVC, however, at max rate the pump can pump about 5000
litres
per hour but I know this will be reduced as the pump is pumping 6 metres
up
in the air before it reaches the filter. My question is this; does anyone
have any idea how much the flow rate will be reduced or how I could find
out? If the flow rate is halved I could use the Hozelock Bioforce 4500
UVC
instead.

What happens if you exceed the max flow rate on the Hozelock Bioforce
range
of filters? Will the unit die because the pressure is too high or will it
just not filter the water as well as it should?

Does anyone have the phone or e-mail address for the Clarke (hippo) water
pump people?

Many thanks

Regards

Yes I know, I have used this pump on this waterfall before and we were happy
with the flow rate. We used to have a Cyprio one I think that cost about
£300 odd quid which was fine at first but we found we preferred a slower
flow rate after a while so we were running a pump that was heavy on juice
and restricting it's flow with a valve. When it died we got a Hippo 2 which
used a lot less power and gave us the perfect flow rate without restriction.
I didn't really expect much from the hippo 2 but was pleasantly surprised.

Does this mean it would be OK to use a Hozelock Bioforce 4500 UVC instead of
the 9000? The pond is split into three tiers with a total size of about 1500
Litres. Could you be more specific about flow rates/ your opinion if
possible?

Thanks.
