Description
Reef Builder is a dry carbonate supplement that raises alkalinity without driving pH up sharply, which makes it useful when alkalinity has slipped but your pH is already where you want it.
Dry buffers are the economical way to hold alkalinity on a larger system and they store indefinitely next to a mixed liquid. Dissolve it fully before dosing, add it into high flow rather than over corals, and raise slowly – alkalinity is the one parameter where a fast correction does more harm than the original deficit.
This size is the economical pick if you dose daily or run a larger system.

- All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
- Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
- Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
