sera gH-Test FRESH WATER, PONDWATER TESTINGCARE

It simplifies the process of tracking total hardness levels for around 420°dGH. If the GH values are too low, we suggest using sera mineral salt. To decrease high total hardness, mix in R/O water. For producing softer water, consider adding sera blackwater aquatan or filtering through sera super peat.

Directions for use:

  • Shake the reagent bottle thoroughly before use! Avoid letting the water being tested come in contact with aquarium or pond water!
  • 1. Rinse the measurement vial with the water to be tested multiple times, then fill it to the 5 ml mark. Wipe the outside of the vial to dry.
  • 2. Add the reagent drop by drop. Gently shake the vial after each drop, until the color transitions from red to brown and finally to green.
  • 3. The quantity of drops used represents the total hardness (in °dGH). For example, 5 drops equal 5°dGH.
  • 4. Cleaning: Rinse the vial thoroughly with tap water before and after each test. Immediately close the reagent bottle after use. Store it at room temperature and away from light. Keep it locked up and out of children's reach. For testing ornamental fish aquariums and pond water only.

US Information for use

Most ornamental fish come from regions where the soil is low in minerals. However, in many other parts of the world, the opposite is true. Rainwater leaches calcium and magnesium from the soil, resulting in hard water. With the sera gH-Test, you can swiftly assess the precise total hardness. Understanding natural conditions aids in selecting the ideal fish species for a community aquarium and is essential for successful breeding. To reduce high total hardness levels, mix in R/O water. Using a combination of sera aquatan and sera blackwater aquatan or filtering through sera super peat will help achieve soft water, which is necessary for many South American fish (such as those from the Amazon basin).

Good OEM replacement, but check the contents
Size: (Pack of 1)
This filter was perfect for my 2020 ram 1500, however I had to get a replacement because the gasket was not included in the box as delivered. I contacted the seller and they replaced it within two days. The replacement unit had both the filter, and the gasket in the box it should've been.

democracy in action or am I allowed to vote
Format: Paperback
This is a superb document on the history of voting rights in America from its founding to 2000. Well worth reading about the struggles of Americans to get the vote. The discussion of suffrage for all Americans. How those that had the vote trying to prevent other people from getting the vote. We struggle with this today, given that President Drumpf is more than willing to disregard the majority of American voters. Our democracy beware and here is the history.

Incredibly well researched
Format: Paperback
Purchased in light of the current election fraud/security debates. I learned nothing so far is new. Data intensive. Can be dry at times, though many of the quotes from historical figures are revealing as to prevailing attitudes.
