Cleaning out the filter...

In the gene pool? Yeah, we could stand to clean up the gene pool but thats not what this is going to be about.

So... As the filter is one of the few things I've got right in the pond (size not withstanding...), I figured I'd post one about koi pond filtration and general water health. Cuz believe you me... that pond water can go south in a half a heartbeat.

Now, if you get on the web and do a search for 'koi pond filter', you'll get more sites selling them than you can shake a 1940 Ford Five Window Coupe at! And they can range in price between thirty bucks up into the hundreds depending on size and "accoutrement's".

There's three basic types to choose from. Chemical, mechanical (the ears of men the world around just pricked up on this one lol) and biological - and various combinations of the three...

First, the filter type most of us are intimately familiar with - mechanical. Mechanical filters are everywhere in daily life. The coffee maker - got a fiber filter. That spaghetti strainer? Mechanical filter... These things amount to nothing more than some porous material that allows water to pass through while trapping particles of stuff suspended in the water. Coffee grounds, linguine, you get the point...

The big drawback with these is they can clog and need to be cleaned or replaced fairly frequently. Just like the vacuum cleaner...

Oh... and UV sterilization. What this is... it's a tube that you put somewhere between your pump and filter with a UV lamp in it. It 'damages' algae as it passes by in the water stream, pisses it off actually... When algae gets upset (stressed) it clumps. Makes it easy to trap in a mechanical filter system.

Then there's chemical filtration. The water you get out of most city water supplied is treated with all sorts of chemicals. Chlorine (usually as a gas), chloramine (a much more effective and longer lasting disinfectant) which, when chemically "removed" creates ammonia (that is also produced from decomposing fish 'waste'). There's metals like lead, copper, iron, zinc... In fact, there's even asbestos in minute, almost undetectable amounts in most public water supplies.

We can use chemical filtration to remove not only these metals and gases and other 'stuff', but it's also an extremely effective way to both kill harmful organisms and populate beneficial ones.

Anyone have a fish tank? Remember the activated charcoal you'd put in the filter can? That's a form of chemical filtration. Didn't do much for catching particles of stuff in the water but it'd take out the various chemicals that cause that fish smell.

There's zeolite and Sodium Thiosulfate. These break the chloramine bonds and help remove ammonia from the water.

Even a 0.1% solution of dissolved sea salt is highly recommended in a koi pond.

Next time you go to the pet store, check out the filter isle... You'll find shelves full of chemicals.

And then there's biological filtration. According to "The Koi Guy", you need nothing else for long term pond filtration. So long as you don't mind a greenish tint in the pond...

There's a wide range of creatures that clean, scrub, produce beneficial chemicals and gasses... Little microbes like certain bacteria, algae (the green, filmy kind... not that stringy, brown stuff). There's tadpoles and snails and fish... All manner of things that scrub out bad stuff and create good stuff.

All of these creatures can be had at any local pet store. Most of the micro-biotics come in little jars and bottles that you just pour into the pond and filter. You can get them for free though, next time you hit the garden center (or a neighbors established pond). Just get a liter or two of their water to seed into your own pond.

Me? I use all three types in my pond. There's the two filter pump units. Multi-stage mechanical, chemical, biologic rigs. But before I got them...

I got me a fiberglass planter pot from the nursery store. Laid in a large pore filter pad on the bottom to cover the holes. Tossed in a thin layer of lava rock - so the good bacteria had a place to grab hold and populate. Another filter pad on top of the lava rocks... 5 pounds of zeolite and activated charcoal and topped off with filter floss (kinda looks like pillow stuffing) and one more large pore filter pad.

All I had to do then was run the pump output into the top of this planter pot filter and let it drain back into the pond. PRESTO! The perfect makeshift multi-stage, multi method pond filter

Plants also help with the filtration, they fight the algae for the nutrients in the water and help keep the water clear.

My pond is 10' x 13' and I use the UV system and lots of plants, lotus, lilies, parrots feather, iris and several types of native blog plants.

I'm glad to see that you are really enjoying your pond.

Yep. Plants too caressme. How could I forget those I have lilies and horse-tail reed. I've taken out the duckweed though. I'll get some more when the "new" pond is ready
