oh yeh but i dont think it will help the clay particles much either though.
its weird but i used to panic a bit about the clayey ponds, not ideal but they seem to go ok.
has anyone come up with application rate for gypsum so she can try that.
maybe ill go through some papers and find it someday.
im thinking it was 40mg/l. dont try it and kill your fish though. check it first. i should write disclaimers from now on.
on a different note, ive got some source water that is stained tea from all the organic matter.
i recently noticed that when i run it through a biofilter for about three weeks on a closed recirc system it became much clearer, initially i had a sechi reading of about 8 inches then after a few weeks i could just about see the bottom. maybe the colour went into the bacterias gut.
