Default Re: iron bonding to phosphate to reduce GSA

Hi Hoppy,
Came up with that because my Altum angel tank which gets a lot of water changes with largely Ro water has quite a bit of GSA no plants so no ferts .Substrate is supposed to be inert but I am running at low phs 5 to 6.5 so that could be affecting availability of iron .There just shouldn't be much iron in there most water changes I've done on a tank .Still I'm light on test work and heavy on supposition .Started to try to bottle neck the iron in my high tech tank so I'll watch which algae drop of first . They do get fed chicken liver a bit that's got probably more iron than the fish will utilize as a after thought .
Regards Chris
