Good post goldminer. Very educative Smile



Thank you Sir. I am nothing more than a tiny fry here, compared to the big fish in this realm.

Most bacteria measure from 0.2 - 0.3 microns in diameter and can be seen only through a microscope (1 micron equals 0.001 millimeters), or about 1/25,000 of an inch across.

Lower grades of Diatomite rock (not to be confused with pure grades of friable/soft commercial filter type diatomite) is primarily composed of the fossilized skeletal remains of microscopic single-celled aquatic plants called diatoms (algae).


Fresh water diatom skeletal remains are composed of amorphous (not cancer causing) silicon dioxide (that silica, in this case = opal). Diatoms skeletal framework is generally tubular in shape, from 5 to 100 microns in size, light, rigid, exceptionally porous, and this grade of Diatomite rock can generally hold 1 to 1.3 times its weight in water.


Consequently, in my humble opinion, as a bio-filtration (bacteria housing media for aqua-culture purposes), certain forms of Diatomite rock is far superior to any existing aqua-culture bio-filter housing, man made or otherwise.

The best DIY artificial (man made) bacteria-housing-media I have had experiance with is heavy duty nylon pot scrubbers.
Which, are neutrally buoyant (at the the ones I have used).
Depending on their size, they have 150 to 300 times the inner/outer surface area of bio-balls.
With a little digging, they can be found wholesale @ very inexpensive prices for bulk lots.
I have read of some folks using them for 10 years & still going strong.
Their color will fade, over the years, but so-what.

Sadly, I have no idea where you might find nylon or monofiliment mesh pot scrubbers / scour pads in kuala Lumpur.
Moreover, if you buy RETAIL, they will cost more.
Best price is wholesale, if you can find the source.

In the USA, we have what are called Dollar stores.
Which sell very inexpensive household items, for $1 each, or per package.
Which is where I found them.

I bought a full case from one of these Dollar stores.
(see attachment)

The shipping label was still on the cardboard case.
From that, I found who supplied them to the Dollar stores, on the west coast USA.
Which is:

http://www.koleimports.com/

There, I found -----> Item # OA231 20 Pk Colored Scouring Pads

Which, are very inexpensive, if bought in case lots.
(20 per pack, for less than I paid for 8 per pack, by the case)

However, minimum order is $100 (usd) + shipping.

If you have any area in KL that has cheap DISCOUNT stores, for very inexpensive household items.
I would try there. If you can find them, you may also be able to find who supplies them.
Which could lead you to the least expensive source available.
(unless, you import straight from China).

Sorry, I could not be of more help.
Good luck in your quest.
As always, where there is a will, there is a way.

Re: [goldminer] High Nitrates Level? Try This! [In reply to] Can't Post

after searching arround, including those hyper market, 1 Dollar Store, hardware store here in KL, found that none of them selling nylon type, I think in Malaysia we have only the steel type pad, so i try my luck to order from the wholesale web given by you, and key in the minimum order of us$100, which is 3 boxes of 48 bag (20 pcs each), then... they contacted me today, quoting me the freight charges is US$482 CrazyCrazyCrazy so my total order will be US$110 + US$482 = US$592 = ~~ RM2000, so i give up..

I would not give up YET.
Every nylon or monofiliment pot scrubber I have ever seen in USA.
Were ALL imported from China.
KL is far closer to China, than USA.Wink

Suggest you google search Chinese companies that make these things.
They may be able to tell you where KL, you might find them.
Or, even ship some to you, FAR cheaper than from USA.
Worth a try.

Hi Mark

anyway you can take some pics of your system in all settings to get an overall idea of what you have done.....

thanks

Re: High Nitrates Level? Try This! [In reply to] Can't Post

Hi, I am a newbie and have read through all 13 pages of TT System. I have a few questions :

I am asking my contractor to construct a new pond (12 x 8 x 5(depth)) = 3,590 gallons (US) and a filter chamber (4 x 8 x 5(depth)).

1. Is the filter size OK?
2. Since this is a new pond, Can I use TT system as recommended by Mark?
3. If cannot, what should I do first before converting to TT?
4. I read someone here says that with TT system, I have to change 10% of the water DAILY. Is it true? If not, how frequent?
5. If there is a blackout (pump), will this TT be a problem?
6. Should I buy a pump 1.5 or 2 times more than my pond volume if TT system is used?

Sorry for so many questions as I am very keen to join the koi lover community ;-)

Please advise. Thanks in advance.

Hi Mark

I know you posted this 10 years ago! But your diagram of your wet/dry filter system really intrigues me. I'm thinking of building a new pond and am interested to know if your system is still working and whether it has worked well for you over the past 10 years.

Cheers

G Chee
