Pressure Filters

Hi,

I was thinking of getting a pressure filter with a built-in UV for a pond
that's near 4000 gals. I have a small pond off to the side that's about 60"
dia and 18" deep. I usually grow some plants in that and the water flows
from there into the main pond via a small stream.

The pressure filter is about $700. I want to try to control the greenness
this year. Are they good and worth it?

Here are a couple that I was looking at:

There is other methods that are certianly cheaper. Plant it heavy
enough and the plants will pull out a lot of nutrients algae uses. UIV
works very well but its a never ending means that has to be figured
into the overall cost of pond mainteneance when you need to replace
the UV bulb some of which are quite pricey. However you can use UVC to
cklear up the water quicker, then allow plants etc to continue on with
pulling nutrients out of the water.....no need to run it all the time
once yur water is cleared up. Lots of poeple do just that, use UV to
get a head start on algae control and then turn it off. Perhaps
adding some shade will help as well and if you have fish not
overfeeding them will also cut back on nutrient levels.

You could also add a veggie filter upstream.....Pressure filters are
ok, but I htink for $700 you can do much better. Look at a HOzelock
system with the Bio Force units.....they are a pressure filter, with
UV and do a great job and at a lesser cost if you shop around. Check
out AZPonds.com for best prices if your in the USA....

I forgot more about ponds and koi than I'll ever know!

pressure (bead?) filters are like those used for swimming pools. they
work for a while and then they go anaerobic. ponds are much dirtier
than swimming pools. you need to increase the number of plants in the
veggie fitler. also, consider just a simple bucket filter with some
polyester batting in conjuntion. I had green water earlier. I used
my bucket filter and fed my koi only freeze dried krill and dapnia and
the water is clear to the bottom. have not turned on my UV at all.

No need to evenb thin k of a sand type swimming pool filter which I
seriously doubt yu were not considering to begin with, but more along
the lines of the Tetra or Eheim or Oase or Laguna pressure filters
commonly used in smaller ponds. Yes they work and work fine........but
without doubt the HOzelock "Bio Force" pressure filter with UVC is
about the best bang for the buck especially when it comes to support
and the price of replacement UV bulbs, as some of the other brands
have oddball high dollar UV bulbs. The higher price for the bulbs
does not make them work any better.....I run a system on my wifes
preforms thats good for 2000 gal. I have a few p[reforms coupled
together and probably opull close to 1800 to 1900 gal of water and its
clear. and algae free......and that is in full sun in the hot sunny
south........with quite a heavy fish load......albiet they are loaded
with mainly tropicals its still a heavy load. Even when we had goldies
and smaller koi in them the Bio Force worked great...Probably $450 or
less for a Biiio Force to suit yur 4000 gal cap....possibly cheaper if
you shop around or catch a sale. I found one that wa in use for less
than a month for $50.....complete with 25 feet of corrugated smooth
interior hose ....as well as a fiberglass water fall weir....Certainly
no need to spend $700 for a filter to work on 4000 gal of water.
