well, i used tap to fill up, and with my new-found knowledge plan to use RO
(from a store) to top off, considering how little my tank is i didn't think investing a an RO
unit was a wise choice (especially with college fees coming round again! lol). So my theory was i could use it to mop up the phosphates in there now, and then by using RO
to top off/water change, i would eliminate it altogether!
Well, thats the plan - I was just wanting to know if the phos-x worked, o if it leached anything into the water
Thanks gotz_potential and vega for your info
Bearfan if my thinking on the situation is wrong please let me know (I use a tiny amount of flake food, but mainly blender mush to feed them!)
