Hey Bud ,
That sucks . Yeah you can tryn get rid of it w/ 3% H2O2 .

Try 10ml. / 2tsp. per gallon and yes run the system as usual / leave it in there perm. it degrades / hydrogen only lasts a cpl. days and it ends up H20 . It evaps. or breaks down / disappears I'm baked n forget the whole story .

Don't ever mix H2O2 w/ hygrozyme or hydrogard though as it'll kill all the benefical organisms in it .

Also search "Sucanat" on here . I posted a good article on here by Ed . It doesn't give amounts or ratios though . I use a tsp./ per gallon disolved and added to res. and have had good luck w/ it . = All natural organic sugar w/o all the goop/build up of molases . Seen it settle in bottom over time but never any mold etc...

Later Bro.
