You said to use it with the water but remove charcoal during use. how long should you wait to put charcoal back in filter?? confused?

Answer by Chewy • Jul 24, 2019
The carbon filter and charcoal can be returned after 6-8 hours.

Will this affect loaches or snails? Thank you in advance...

Answer by Chewy • Mar 01, 2018
We recommend that you remove them from the tank while treating. You can return them to the tank after you have finished the last dose, completed a 25% water change and have left the new carbon filter cartridge in your filter for at least 8-12 hours.

Is the treatment safe to do while having fish in the tank?

Answer by Chewy • Jan 16, 2023
Fish can remain in the tank during the treatment, as long as they are not scaleless. This product cannot be used with live plants, snails, shrimp, etc. Do a partial water change prior to dosing and remove what algae you can. Remove the carbon from your filter to prevent it from removing the chemical. It only needs to be removed for 5-6 hours before being put back in. The chemical works for up to 72 hours to destroy the algae. As it dies off, your cartridge will catch it.

Do I drop this right in the tank or in the filter?

Answer by Chewy • Dec 11, 2020
It is recommended to add tablet to aquarium water. Remove carbon from filter during use.

Read entire label....

Definitely read the entire back before ordering.. DO NOT use if you have snails or live plants. Yea, I have both.. wasted my money.

I purchased this product to help with the algae in the tank. I dropped one in there and my pet bit into it and died the next day. This is a very sad situation because we had him for over 13 years. I thought these products were pet friendly but I guess I was wrong. Thanks for breaking my heart and for making me sad. You guys need to do better.

This added yellow scuz to my tank

This did NOT do anything for the algae but instead tinted the water yellow and added a yellow hazy scuz to the glass. A complete waste of money.

Algae

My tank had an algae problem that I tried several product but did not work. I treated the tank about 3 weeks ago and it's still clear.
