Hi clive. Ive seen this stuff for sale. I dont know what percentage normal bromo solutions are but does it need a different 4dkh to bromo ratio mix than standard

That should be the normal range. Perhaps less to save money. Check the box in an LFS when you're there and see if it gives the percentage.
