Seachem Alkaline Buffer – Raise KH & PH In Freshwater Aquariums (Multiple Sizes)

If you're keeping a freshwater tank and struggling with low alkalinity, Seachem's Alkaline Buffer is the fix.

It's designed to raise KH and stabilize pH, making your water less likely to crash.

This stuff is brand new, comes in various sizes—70g, 300g, 600g, or 1.2kg—so you can grab what fits your setup.

Just add it to your water during changes or as needed.

It's a buffer, meaning it works to maintain those levels, not just spike 'em temporarily.

Seachem's a trusted name in the hobby, so you know it's quality.

Perfect for planted tanks, African cichlids, or any setup where you need harder, more stable water.

No fancy packaging, just the good stuff inside.
