Hi all, I'm planning on revamping my pond soon and am haveing another go at makeing a filter. I recently got a load of 55 gallon barrels and am going to use loads of K1. Is it possible to have to much. My pond is 2500g and lightly stocked.

Cheers Mark

this depend on how you are using it

I also have a large freestanding vortex which I'm going to make into a really big easy and then going into a couple of blue barrel easy's and then a barrel of aerated K1. I'm expecting to use quite a bit of K1

so you want the otherone as bio you should fit 150 in that not all at once as it foalts im lead to believe

There is a ratio for using K1 in a filter bay, here it is

So, how much K1 do you use for a given size chamber?
The ratio of the volume of K1 in relation to the chamber volume is quite important. You need to calculate the volume of your chamber in litres. To calculate the volume of your chamber in square inches multiply the length by the breadth by the depth (L x B x D). Then multiply by 0.0164 to give the number of litres. Centimeters are easier, simply divide total volume by 1000 to give litres.
It is possible to use no less than 30% to a maximum of 67% of this volume with K1. An average of 50% is recommended.

Examples:
1. Tank 24" x 24" x 24" = 13,824 square inches.
Multiply by 0.0164 to give 227 litres volume of the chamber. Then multiply this by 50% to give 113.5 litres of media (recommended).

2. For a 24" vortex with a straight side 24" depth to the cone of this would be 12 (half its diameter) x 12 x 3.14 (pi) x 24 (height) = 10,581 square inches. 10,581sq" x 0.0164 = 178 litres. = 89 litres of media at 50%

Although Nexus say K1 can be added to the Nexus as your stock grows but i would start off using the formula

this is a time wrap machine you will have to post the pics again wallace what a piece of work in a good way

As you are lightly stocked, you can calculate the total weight of fish ,feeding regime and pond volume too give you the correct amount in ltrs of K1. To much k1 in the chamber and the bacteria do not work efficiently.Here's a good link to filtration and easy to understand.

the link won't load, i will try to get it asap

yes its really next tuesday today

koimaster

try pm'ing it

i was told 100 -150 depending on stocking and if air was present
