Adding a bit to John Hicks comment.(posted 8123 days ago)Describing XTOL as low-sulfite formula can be a bit misleading - it has a lot more sulfite than Ilfosol-S 1+14.
The working pH of XTOL is below that of D-76H, while that of Ilforsol-S is much higher. Either way, XTOL and Ilfosol-S are VERY different developers.
