Brightwell AquaticsAlkalin8.3 Concentrated KH Buffer Supplement - for All Marine Fish and Reef Aquaria - Aquarium Water Treatments, 8.45 fl oz

Great product, works as described for the hobby

Have a small 16g biocube tank and the few corals and GSP deplete the KH . This has been amazing to keep KH up and toadstool happy. Without changing ph. Dose about 2 ml a day and recommend ml syringe vs cap

Works really well! Now I put it in my doser to keep everything level! Moved onto buying the bigger one!

Trabaja excelente incrementa el ph👍🏻

Have used this to keep my alkalinity on the money since i set up my nano reef 2 years ago. My corals have thrived. Balanced alkalinity alsi balances PH too. Remember to test your parameters regularly.

My last session came in at around 6h!! This stuff is amazing

Does what it says it will do. Dosing it at 20mls a day for my tank and keeping a stable dkh 8.5 and PH at 8.3

Lowered my ph every time I added it. Struggled to keep it above 7.8 until I stopped adding it and switched to Seachem Reef Fusion 1 & 2. Would never recommend.
