i posted a question on a thread regarding bio-media and cant find the thread again and was wondering if you could help.:nilly:

someone posted that industry standards say use about 2.2 gallons of bio-media (like ceramic rings i presume) per 100gal of water, i then asked how many kilograms one gallon of bio-media was and would like to know the answer so i can calculate my 268gal filtration requirements. i will be using about 11kg ceramic rings and about 10 kilos river pebbles in the sump, about 200 bio balls on the wet/dry part with a 18 000L/h mag drive pump.

will this be enough to handle a largish bio-load?:) :D
 
ceramic rings will hold a different amount of bacteria than bioballs, so the comparison cant really be made. (unless you know the surface area of each)
 
Correct, each bio-media has its own calculation based on surface area; not the weight or volume. Often a manufacturer does the calculations for each media so that you only need to order a specific volume for your tank. For example, river rocks have high weight and low surface area, and Bio-Balls have high surface area and low weight (they float).

Additionally, a gallon is a volume measurement just like liters. Pounds(lb) is the weight measurement like kilograms.

1 liter = .2640 gallons
and
1 kg = 2.205 lb

Well, actually that is how we measure gonads.

The reciprocal of the conversion is:
1 gal. = 3.7875 L
