Features: A PH meter is an electronic device used for measuring the pH which is either the concentration of Hydrogen ions in an aqueous solution or the activity of the Hydrogen ions in an aqueous solution. The pH will indicate if the solution is acidic or basic, but is not a measure of acidity or alkalinity. -PH meters work in liquids though special probes are sometimes used to measure the pH of semi-solid substances. External power supply can measure continuously for 24 hours to avoid reading errors due to low battery power. Digital display for easy reading.

Ammonia and Chlorine and Chloramines remover.   Dosage: 5 g per 1 kg biomass per day (about a teaspoon)   One teaspoon per day in the quarantine pond can do all the difference. Used for more than 10 years at koi shows by us for water quality control and save water and labour. Please contact us for more information on how to use for shows. Assist biofilter while maturing A handy product to have available for first aid in a case of a crisis ----- The active ingredient in ChlorAm-X is sodium hydroxymethanesulfonate, HOCH 2 SO 3 Na (or sodium formaldehydebisulfite for some) 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 my 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. 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 (“Overdosing” We noticed that a relative high dose of Chloram-X resulted in a undetermined or difficult to read colour developed during testing for ammonia.
