Using aquarium test kits to detect problematic water conditions is key to the sustainability of a healthy aquarium. Test kits utilize a wide variety of dry chemical powder and liquid solution reagents and may be supplemented by an electronic monitor.

Elos, Tropic Marin, Seachem and Aquarium Systems test kit lines are all well-regarded for their affordability and accuracy.

For a fish-only tank, you should measure and monitor pH, alkalinity, ammonia, nitrite, and nitrate levels. In addition to these, you should also monitor the calcium, magnesium and strontium levels in a reef aquarium. By testing your water, you will know what additives you will need to use to keep your tank at its healthiest.

Phosphate, silicate and nitrate levels have a significant impact on annoying algae growth. Test kits can be quite handy, should you run into problems with excessive algae growth.
