Well here it is; Brian’s MKII Anoxic Filter
is up and running. It cost £105.oo for the black pond coating to paint the
inside of the Anoxic Filter and the total cost for the new filter is about
£450.oo. Here in the US or should I say the upper Midwest, painting the inside
of an Anoxic Filter like Brian did may not be a good idea do to the bitter cold
weather we have. I think more investigation on the pond sealant would be in
order to see if it could stand up to the cold without cracking. A 40-mil Butyl liner
on the other hand will expand and contract enough to prevent such cracking.
After all they use the stuff on roofs.
So what do you get for this kind of money
in an Anoxic Filter verses a filter out of the box? An Anoxic Filter this big
at a 50% increased in capacity than his old Anoxic Filter had is a big jump in
size. It would take at least three Nexus 300 filter to equal this one Anoxic
Filter. That would be a whopping $
15,000.oo USD in comparison spending to equal this Anoxic Filter. Über
expensive yes, but only for the hobbyist that has the money for such equipment
will take that path. Most hobbyists will only add one Nexus filter and realize
in the end that they need more filtration as time goes on. That is why I have
always said I have never seen a Nexus filter as a stand-alone filtration system
for a pond without a supplement filtration system added to it.
The filter has the capability to have
12,000-15,000 gph of water pumped through it. If you can afford the electricity
to run such high volume pumps then the Anoxic Filter can deal with that kind of
water volume. A Nexus 300 has the capacity to handle about 3600 gph of water pumped
through it so it would take about three of them to equal that kind of water turnover.
The working capacity of an Anoxic Filter this big and three Nexus 300 filters
is about identical but as for as cost goes there is no caparison. There is no
way you could get three Nexus filters for £450.oo completely installed. As far
as bacteria capacity the Anoxic filter wins hands down. There is no substitution
for cubic inches of media.
Thanks Brian for your informative pictorial
history of your MKII Anoxic Filtration build.
Cheer,
Kevin

The basket you can see are all the ones from the
MkI so I manages a 50% increase (don't tell the wife) I went to my local garden
center to see if they had the ones I wanted, but they were £2 each...online £1
each so I gotta wait.

I didn't realize just how big it is and need to
order another 25 baskets taking the total including the planted ones to 56.
