hi, i'm just after a little reassurance here, as i am now completely cheesed off with the outcome of using a bag of the above (along with 2 bags of the ordinary) which i added to my 300 liter tank. i use 2 t/tec ex1200's and a koralia 1 and there is a constant turnover of particulate aquasoil in the water column, along with a 1-3mm coating of it on every leaf in the tank. granted, there are 4 cory's in there which truffle about, but i never expected this. in 5 weeks i've so far changed 5 of the filter flosses and renewed the noodle media in both filters because of clogging, and the once smoked gray spraybars/inlets are now dyed a sludgey brown colour from within, and there still appears to be no end. the last straw came today after pulling up 10 or so stems of p/stellata (for trimming) at 11am, and i can now (9.30pm) just about make out the back of the tank. don't get me wrong, i know to expect some bits flying around even after a slight diturbance, but this is absolutely ridiculous, i used to get upset if a bit of peat or vermiculite reared its head after a minor uprooting through capped substrate. what i now have in mind, is to ditch the substrate completely and renew with 5 bags of ordinary as amazonia 1. what i would like to know is, will this be the answer to my problems, does anyone have any trouble with this becoming waterborne in a reasonably fast flowing system? would just like a bit of moral support before spending another 200 quid plus on more substrate! cheers and thanx in advance, bazz!
