Anyone want to help me out? I need about 50l of the stuff, not going to be cheap.
blimey! just how big is that tank??!
Must be a lake
15 gallons, 2x fx5's to fill so really it's just a guesstimate.
unmodified, the media capacity of an FX5 is only 5.9 litres.. are you sure you got your maths right?
Really?! Then yes, I have my maths wrong, very wrong.
does it HAVE to be sintered glass?
I've always used alfagrog.... can get a sackful for a pond filter for peanuts... it's porous and ceramic... and it does the job!
with the amount of turnover your filters going to have on such a small tank Garuf, filling it right up with media is probably a waste of money.
As Ed said on a different thread.. a tank is only going to produce so much NH4, so only a culture of a certain size is going to form anyway.. with a tank so small, on a filter so large, whats the point in filling it right up with expensive media if the culture might only use say 25% of the surface area available anyway?
Id fill it up with polishing pads and other things that are cheap as chips, mainly to slow the thing down!! use 1 tray for biomedia.. you have no need to use any more than that.
