Can I used this with Stress Zyme and stress coat? Also, I'm doing partial water changes (like 5 gallon to 29 gallon tank) that I'm leaving the water out so to dechlorinate it. Do I dose based on the amount of water changed for each product (if able) or for the whole 29 gallon tank? Thank you!
Answer by ChewyJan 21, 2022
API Aqua Essential can be used in conjunction with any other API water conditioner or medication. Using the dosing cap on the bottle, add 5 milliliters per 50 gallons of aquarium water to treat tap water. Add 5 milliliters per 10 gallons of aquarium water to remove ammonia, nitrite, and nitrate. We advise you to wait 24 hours after dosing then do a water change. If you dose within that 24 hour period there is no danger to the animals/plants in your aquarium. A follow-up water change is always beneficial to an aquatic system.
