Hey thanks to the original poster. This might be a bit off topic but personally feel like its bull shit that 90% of the fertilizer/ plant supplements are sold in the liquid form. I know with aquarium products, a few years back it was the same exact thing, 99% water 1% of what you want. Now it's gotten to the point where no one buys liquid supplements, most of them are sold as powder. For instance instead of buying 1 gallon of liquid calcium, now you buy 1 gallon of powdered calcium that makes 5 gallons of liquid calcium. It's cheaper to ship, it's 10x cheaper, and probably a better product. Bulkreefsupply.com is the site, they sell cal,alk, & mag, just incase you guys wanna check and see.
