im looking at upgrading to a 10x4 or 8x4 tank, and leaning towards a large canister filter for mech, and then into a trickle tower for bio.
I'm in the uk so the ultima filters aren't available, but we do have similar ones called k1 micro bead filter, however these are approx £1000.
Also sold here are swimming pool sand filters like below, 18" diameter for only £200?!
They look very similar and the one below is made of fibreglass.
Is it possible to retro fit these for use with k1 media. Anybody had any success doing so, or any reason why not possible?
