Continuum AquaticsFlora-Viv KH+ - Professional Alkalinity Boosting KH & pH stabilizer for All Freshwater & Planted Aquariums, 500g

The last one that I got was rock hard. I kept it but it’s a pain because I have to scrap any amount loose to use it.

Increases water hardness.

I am trying this instead of seachem neutral regulator, so far so good. I had bacterial blooms with my seachem/ phosphate one.

Excellent product

Best brand

Does exactly what it says it will do!

Got the product and it broke in the bag during delivery. Read the directions only to find out I need to buy another product just to use it....
