Question 1

Is this real evolution aqua k1? i bought media advertised as k1 on amazon & it's bigger than the real k1 i already have so it's a knock off.

Accepted Answer

Thanks for your question! Anything sold as Evolution Aqua K1 Media ought to be the authentic material, so I sympathize with you that you received an inferior item. While I cannot speak for every seller on this listing, we purchase directly from Evolution Aqua USA, so you can be confident that what we offer is the genuine media.

Question 2

is this 25 or 50 liters? and how much many bags would  it take to fill a 55 gal barrel?

Accepted Answer

This listing is for 50 liter.     How much it would take to fill a 55 gallon barrel partly depends on how tightly you want to fill it.  If you are making a moving bed, the secret to success is that it is loose and can move.    Liquid to liquid, there are about 208 liters in a 55 gallon drum, but it would require less than that to do it loosely.    Feel free to call with additional questions.

Question 4

I have a sand filter for my (small) pond.  Can I replace sand with this material?  Does this material have a longer life than sand?

Accepted Answer

Thank you for your interest.  
There is more difference between a quality Pond Filter and a sand filter than just the media.   The laterals in a sand filter have very small perforations so that the sand does not escape.    Therefore, with a sand filter, even if you replace the sand with a good quality "bead filter media" your filter will still clog more frequently with dirty pond water than you will likely appreciate.    It would be well worth your while in the long run to buy a K Plus Pressure Filter with all of the arts to begin with.    Filters and the laterals in them are designed for different medias and different flow rates etc.   You can make your own filter and use one of many medias but your results will be less predictable and won't come with engineering specifications that you can count on.   Results will vary.
