Aquaforest KH Plus 250mL

Aquaforest KH Plus is a concentrated liquid alkalinity solution that raises your reef tank's carbonate hardness (dKH) without increasing the concentration of other elements. Stable alkalinity is one of the most important parameters for healthy coral growth and color, and KH Plus lets you correct shortages or sudden drops quickly and precisely.

Benefits

• Raises dKH without affecting calcium, magnesium, or other parameters.
• Concentrated and precise, so a little goes a long way.
• Supports coral growth by keeping carbonate hardness stable.
• Pairs with Ca Plus and Mg Plus to balance the reef big three.

How to Use

Test your alkalinity first, then dose KH Plus gradually to reach your target dKH, following the Aquaforest dosing guidelines. Avoid large swings by raising alkalinity slowly and retesting between doses. For best results, dose separately from calcium supplements.

Frequently Asked Questions

What is the ideal alkalinity for a reef tank?
Most reef keepers aim for 7 to 9 dKH and keep it stable. Consistency matters more than chasing a specific number.

How fast can I raise alkalinity?
Raise it slowly, no more than about 1 dKH per day, and retest between doses to avoid stressing corals.

Can I dose it with calcium at the same time?
Dose alkalinity and calcium separately, with some time between, to prevent them from precipitating out of solution.
