My friend read geez's excellent posts, one talks about post reaction cleanup. He has done an LWR (10g e.hcl, 14i, 4rp, 10ml dh20) and since:
----------------------------------------------------------
"If the fluid is reddish-orange, but the red phosphorous falls like bricks to the bottom, you likely have an excess of iodine present in the reaction fluid"
----------------------------------------------------------
is true, he tried to boil the sollution but i didnt help much. Tried to wash with NP, _several_ times, but all NP turned piss yellow.
Tried to boil again for 15 min, didnt help much either. Tried to get sodium thiosulfate without success. Aquarium stores here dont carry any brand that contains this.
What should he do?
He obviously cant wash for ever in NP, the sollutuion just seems to dilute minute amouts of i2...
Everything else has gont according to plan, swim dosent want i2 in is product...
