Frequently Asked Questions (FAQs)

1. What can I use to make my fish tank water clear and cloudy?

Add activated carbon media to the filter, whether loose or carbon pads. Adding activated carbon media or activated carbon pads to the filter will help clear the water and adsorb nutrients that feed the bacteria bloom.

2. Is seachem clarity any good?

It may be more expensive, but it's a price to pay for quality and you get what you're paying for. The Seachem Clarity is an spectacular product, it works like no other, however, it's necessary to dose it very carefully because the product is extremely concentrated.

3. How often can I put clarity in my tank?

A: Clarity™ can be added every 24 hours as needed, however, if your water has not cleared you may not have adequate mechanical filtration. We recommend using filter floss (poly-fil) in your filter when adding Clarity, as this is a very fine mechanical filter that will remove the undissolved particulates.
