Brightwell Remineralize 500 mL

Brightwell Remineralize is a liquid mineral supplement designed to restore general hardness (GH) and essential minerals to soft or purified water. It is especially useful for hobbyists using RO/DI or rainwater, helping rebuild the calcium, magnesium, and trace elements that fish, shrimp, and plants need for healthy growth.

Stable, properly remineralized water supports molting in shrimp, strong scale and bone development in fish, and overall livestock health. Use it to remineralize purified source water when preparing new aquarium water or replacing minerals removed through water changes. Do not routinely add minerals to evaporation top-off water: evaporation leaves dissolved minerals behind, so plain RO/DI water is normally appropriate for top-offs unless testing identifies a specific deficit. Always follow the dosing instructions on the bottle and adjust based on your target hardness and tank volume.

Frequently Asked Questions

What does Brightwell Remineralize do?
It adds back the minerals — including calcium, magnesium, and trace elements — that are stripped out of RO/DI, distilled, or naturally very soft water, helping you reach a stable, livestock-friendly general hardness.

Who should use a remineralizer?
It is ideal for hobbyists keeping shrimp, soft-water fish, or planted tanks who start with RO/DI or rainwater and need to rebuild minerals before adding livestock.

How much should I use?
Dosing depends on your starting water, target GH, and tank volume. Always follow the dosing instructions printed on the bottle, and use a GH test kit to confirm you have reached your target.

Why does remineralizing matter for shrimp?
Shrimp rely on stable minerals, especially calcium and magnesium, to molt and build healthy shells. Consistent remineralized water helps prevent failed molts and supports long-term shrimp health.
