Hi all, i'm stripping my aquascape and starting again, it has been setup for 6 months, i have never cleaned the substrate (Carribsea EcoComplete) as my tank was 100% planted, however it is a bit of a mess so i tried to vacume it a little bit only to find that because it is so light that it just siphoned up the tube with all the muck, so how do i go about cleaning it? I would usually just leave it but my new aquascape will pretty much have a entire riccia carpet so there will be very few rooted plants to feed off the muck.
