You cannot correct what you have not measured. Marine test kits cover ammonia, nitrite and nitrate while a tank is cycling, then calcium, alkalinity, magnesium, phosphate and nitrate once corals are in and consuming them. Salinity is measured with a refractometer or hydrometer, and pH and temperature with a probe or a digital monitor.

We stock Red Sea, API, Aqua Medic, Seachem and Fluval kits, plus Triton Lab water analysis for a full elemental breakdown sent away to a laboratory.

Test kits have an expiry date and reagents drift as they age, so a kit that has sat in a warm shed for two years is not telling you the truth. Test at the same time of day for results you can compare week to week.
