Pressurised filters
Hi
I'm looking to replace my Hozelock pressurized filter with either an Oase or Fishmate model. Does anyone have any useful feedback about these filters. The single BIG advantage as far as I can see is that the spnges can be flushed through in situ, so no more struggling to dismantle and reassemble the filter! Any comments would be appreciated! Thanks. |
I purchased an OASE filtoclear 3000 (pondliner.com) for my 1800 gallon
koi pond. I left the UV light in the filter off initially to let the starter bacteria get established. I'm using a Sequence 750 pump (AZPonds.com) with a skimmer & leaf trap prefilter. The leaf trap has already saved one of my baby koi when he investigated where the the bottom drain led to. I figure with the line losses and waterfall I'm pushing between 1500 to 2000 gallons an hour though the filter. When the water starting turning green after about 2 or 3 weeks I plugged the filter in which activate the 9 watt UV. Within 3 to 4 days the green water was gone and the water has been pretty clear ever since. The pond is just under 4 feet deep and I can clearly see the bottom. Cleaning the filtoclear is about as easy as it gets. Just turn the knob to backflush and crank on the handle. I backflush for about a minute and that's it. I spent 2 years cleaning 'in pond' filters and I had enough. I bought for pretty much one reason - clean the flter without getting my hands full of you know what. The quality of the Filtoclear is excellent, it's some kind of tough plastic fairly thick. The mechanisms were stiff at first but once it's in operation everything turn and pulls smoothly. There are two types of filter media one more coarser that the other. Oase says this is to foster the growth of different bacteria. The filter comes with stepped adapters for hoses up to 1-1/2 inch diameter. To increase my flow rate I chose not to go with the provided adapters. Instead I threaded 1-1/2 inch PVC plumbing (couplers) directly to the filter. It worked out pretty well. I highly recommend it. "question" wrote in message ...

Just in case they didn't mention it in the literature. Pressurized systems
really eat up the buffering (KH) so you should have a test kit for that. They also work best when the KH is at least 150 ppm. Put Baking Soda on the grocery list. :o) ~ jan On 15 Aug 2004 13:36:35 -0700, (Rich L) wrote: I purchased an OASE filtoclear 3000 (pondliner.com) for my 1800 gallon koi pond.

Hi Jan ... I have a PF3000 which is a pressurized filter. Now I know why
the KH was never a stable number. The things you learn on rec.ponds.... just incidently! Thanks a million.

om... I purchased an OASE filtoclear 3000 (pondliner.com) for my 1800 gallon koi pond. ... Does this need an additional pump, or is one built in? We were considering the UV solution, and this kind of integrates a UV and a filter, so might actually be worth the shell out of cash... -- Gareee© (Gareee "at" Charter "dot" net) Homepage: http://www.fortunecity.com/tattooine.../mainframe.htm Custom Figures, Wallpapers and more! |
I just learned about it a year or so ago, so I don't how "out there" the
information is, or how good the dealers & manufacturers are about informing people. It not like it is a flaw or anything, it is just something that one needs to be aware of, as baking soda is an easy product to get and fairly cheap. The unfortunate person is one who had a stable pond system before, went to pressurized due to needing more filter, fish bigger, whatever, and then have a pH crash because the KH, that they never had to worry about before, is used up real fast. Especially if your fresh water doesn't have a lot of buffering to begin with. Glad I could help. :o) ~ jan On Sun, 15 Aug 2004 22:37:38 GMT, "Nedra" wrote: Hi Jan ...

No, not because of the new water, (and dechlor. is always wise when adding new) but something about the pressurized system itself, beats the KH right out of the water. I'm sure it is a chemistry related thing, but I can't tell you what or how. I did send this question into the chemistry expert on the KHA board, so I'll let you know. ~ jan ~Power to the Porg, Flow On!~ |
The KH is consumed to an extent with all filters. The bacteria use the
carbonates to help with the digestion/conversion of ammonia to nitrite, giving off a Hydrogen ion, and then in the conversion of nitrite to nitrate, 2 Hydrogen ions are given off. These hydrogen ions are acid and they use the carbonates to neutralize the acid and convert the hydrogen ions with CO3 to CO2 and water. The pressurized filters, bead filters are generally associated with heavier fish loads than the garden pond with smaller filters, and therefore more food to be converted, more acid, more demand for carbonates/bicarbonates to prevent a pH crash. -- RichToyBox http://www.geocities.com/richtoybox/index.html "~ jan JJsPond.us" wrote in message ...

Thanks for the chemistry explanation RTB, and is what was told to me by
those I asked, though they didn't have the reason why, nor had it come to their attention, regarding pressurized systems using up the KH faster than open gravity fed filters. When you mentioned higher fish loads, I went Ah Ha, but than said, "Wait." Case in point, one of our ponders started out with pressurized, and was about ready to take out stock in Baking Soda the way he went thru it. He has since converted to a gravity fed filter, and says it's a rare day that he needs BSoda... and his fish have gotten bigger in the meantime. So there has to be something directly to do with that type of filter, not the pond, per se, imo. ~ jan On Tue, 17 Aug 2004 00:32:28 GMT, "RichToyBox" wrote: The KH is consumed to an extent with all filters.
