Hi just tuning in. Not sure if this was mentioned but what's the name if that filter. Looks great and sounds like a solid investment
omg, that thing looks like it'd make filter maintanence a snap. Might have to look into one or two...
I could not find any information about this filter via a google search!
Is possible to see what the media looks like?
Is it glass sand or crushed glass noodles/rings as in sintered glass?
I found this info on glass media and it indicated that sand is better for biological activity of the media itself while glass is better for mechanical filtration.

[/URL]Found another article which concludes on p18 of the PDF that Glass is better for the trapping fine particles and inproving clarity.
Glass also resulted in more effecient backwashing and less total media required but there is no comparison with sand for biofilm or bacterial colonisation.
I thus think that while glass has some benefits it still does not have the biological filtration ability of much cheaper sand.

Sorry, I stand corrected sand is a suitable replacement for sand and has other additional benefits as well as being slightly better at reducing nitrates than glass.
Other than it's cost, I may give it go in my sand filter as a media.

I think your research has confirmed my use of glass. It all points to efficiency in the backwash, clarity, and pump energy required. How much biological is required for a tank? If you got 0 ammonia, 0 nitrite you got enough. Balance of mech/bio is key.
I've only come across one person on the forum that knows how to use sand in a filter to remove nitrate and you can't do it with a pool sand filter.
Very good read. Let us know how it works out for you.
Hi Ken, that should have been "Glass" not sand but I think that was obvious from my post or the info in the articles.
I am stopping on my way to work to get a 25kg bag of glass filter material for my pool filter which I use in conjuction with sump.
It polishes my water very well and I sure it provides some biological filtration but I certainly would not expect it to cope with my 2500L tank alone.
As for people using sand for nitrate reduction, anyone on the forum that uses a fluidised bed fliter would know that power of moving sand as a biological filter media.
Do you recommend putting a layer of fine pebbles in pool filters first before adding the media to aid the flow/backwashing/rinsing?
