PondPrep Ultra Dechlorinator by SuperNatural
So, you’ve got your pond filled with water and you are excited to add fish and plants. Not so fast! City water is full of chlorine and if you add fish and plants without removing chlorine you could be putting fish and plants in danger. PondPrep Ultra makes your pond water safe for fish and plants by removing and detoxifying chlorine, allowing you to spend more time enjoying your fish and less time worrying about them.

Features:
You can use rainwater to fill your pond, but keep in mind that it is very soft water. If you primarily use rainwater, be sure to check your pH regularly because it could become too low and cause serous problems.
