Aquarium Test Kits - Marine Depot

This test kit simply says “dip and read” and that’s essentially the gist of how to use aquarium test strips. It measures for pH levels, nitrite, nitrate, carbonate, and hardness. It comes with the usual charts to compare the results with and there’s moisture protection to ensure the strips aren’t contaminated before use, ensuring accurate results. This includes 25 strips in a stay-dry package.

Inexpensive and long-lasting, freshwater aquarium test kits can save you a lot of trouble.

For most aquarium test kits, shelf life can range from 6 months to 2 years (sometimes even longer). Make sure you pay careful attention to the expiration date and replace testing supplies once the expiration is reached (or your results might not be accurate!).

90 tests, nitrate test kit freshwater/saltwater aquariums. Fast easy and accurate. Now for my question. After eight weeks of water temperatures averaging in the upper 40s to mid 50s (Fahrenheit), the pH is still 7.2 and there is still no trace of ammonia, nitrite or nitrate. I can understand a functioning nitrogen cycle will leave no ammonia or nitrite, but where is the nitrate? The test kit I use is new and gives me readings when testing my aquariums, so we can rule out a defective kit.

An aquarium water test kit is needed if you want to be successful in the tropical fish hobby (freshwater or saltwater). You will need to know how to test your water during new tank start-up (the cycle) and whenever problems arise.Some aquarium test kits come as dip strips that you dip in a test tube filled with water from your tank. You then compare the color with the card that came with the kit to get your final reading for each particular test. The other type of test kit has liquid droppers. You dispense the liquid (certain number of drops) into a test tube with tank water. You usually need to shake the tube and wait a few minutes for the test to develop. You then match the color of the water in the test tube against a test card to get your final reading. It can be a good idea to ask someone else in your house to compare the colors and give you a second opinion. Don't tell them what it means, just ask them to match up the colors. As hobbyists, we may tend to skew the results in our favor, so a second opinion may help keep us honest.
