Testing with Cloram-X
ClorAm-X is a handy product to have around in an emergence if you suddenly are faced with more ammonia than you filter can handel. But you still need to test the "free" ammonia to ensure the safety of the collection.
Water treated with ClorAm-X will give false (high), off-scale readings with ammonia test kits that use Nessler's reagents. Water treated with ClorAm-X is compatible with most salicylate and phenol/hypochlorite test kits.
I have tested a number of available kits (including our Hanna ammonia digital colorimeter) and found the Tetra kit the only one that remained accurate. The dry-tab test from Interpet was surprisingly inaccurate even without Chloram-X.
I also use with success a salicylate tablette type kit (but the name escapes me now)
Water treated with ClorAm-X is compatible with all known nitrite and low-range nitrate test kits.
Water treated with ClorAm-X is incompatible with Winkler and modified Winkler dissolved oxygen (DO) test kits. These kits will give false, low, or zero, readings. However, water treated with ClorAm-X is compatible with indigo/carmine dissolved oxygen test kits and with dissolved oxygen meters.
Be aware of pH instability at low alkalinity (<50mg/liter CaCO3)
Noticed that a relative high dose of Cloram-X resulted in a undetermined or difficult to read colour developed during testing for ammonia. Yet the Cloram-Xit will not kill the fish.
The active ingredient in ChlorAm-X is sodium hydroxymethanesulfonate, HOCH2SO3Na (or sodium formaldehydebisulfite for some) a patented product. (I question this information. Investigate.)
Beware of "funny reacting" type in the market. They are fake. It should have a faint chlorine smell and I wonder that come from?
