Axolotl RO Water Kit

Prepare RO/DI water with separate control over general hardness, carbonate hardness, and mineral replenishment. The Axolotl RO Water Kit contains three Brightwell freshwater supplements for a measured water-preparation routine.

What's included

• Florin Delta GH+ — 250 g: general-hardness mineral supplement.
• Florin Delta KH+ — 250 g: carbonate-hardness and alkalinity supplement.
• Remineraliz — 250 mL: mineral replenishment for purified water.

Test, mix, and recheck

Measure GH, KH, and pH before dosing. Prepare replacement water in a separate clean container and follow each current product label. GH+ and Remineraliz both increase GH; account for their combined contribution rather than automatically adding a full dose of each. Recheck after mixing and match the aquarium's temperature and intended water chemistry before use. TDS alone does not replace GH and KH testing.

KH+ is formulated for freshwater systems targeting pH 7.8 or below. This kit provides adjustable supplements, not a fixed universal recipe or a guarantee of particular readings.

An RO filter, water, test kits, measuring tools, and dechlorinator are not included. Supplier images may show alternate sizes. Brightwell Direct fulfills the component products; shipping is calculated at checkout and items may arrive separately.
