Frequently Asked Questions

How often should I replace this carbon filter?

Replace every 1,500 gallons, or sooner if you notice a chlorine taste or a significant drop in flow rate. Tracking gallons filtered is the most reliable way to time replacements.

Does this filter remove chloramine?

Green Coconut Carbon reduces chlorine and many organics. For complete chloramine removal, consider the ChloraShield carbon filter upgrade instead.

Will this work with other HydroLogic systems?

This filter is sized for Merlin-Garden Pro housings (17.25in H x 2.75in W) and is not interchangeable with other HydroLogic system families. Confirm your housing dimensions before ordering a replacement.

When should I check for a chlorine taste in my filtered water?

Check periodically as the filter approaches its 1,500-gallon replacement interval. A returning chlorine taste or noticeable flow reduction both signal the filter is due for replacement.
