SeachemReef Carbonate, 500 ml

Q: Can this be used in a fresh water aquarium for raising KH? Thanks

I would not use this in a freshwater tank. If you are worried about hard/soft water or you want a ph change for a special plant. I suggest you put a baggy of crushed coral in your filter and let that dissolve over time and repeat every few months. However having both a large reef aquarium as well as a smaller freshwater aquarium I have never really had to worry about my KH in my freshwater. In fact I use no chemicals in my freshwater tank as it's so easily self sustaining. Also not trying to sound like a jerk here but it's gonna come out that way I am sure, but if something says REEF or SALTWATER don't put it in freshwater. There are only a few things that can be used in both and this isn't one of them. Ben

Q: Will I still need to add a pH buffer to supplement this product?

NO---This product will maintain the necessary alkalinity and ph

Q: My small bio cube has a kh of 7.3 and calcium at 390 i own a bottle of reef carbonate is there something else i should also buy to get this in check?

I use the reef carbonate to increase my KH.. I keep my KH around 10 in my 93 gal mixed reef. You should try to keep kh above 8 if you have hard corals imo. Reef carbonate does not contain any calcium so you need another source. I use ESV b-ionic calcium to maintain my ca level at 450 or higher. Hope this helps

Q: What's the difference between this and Seachem Liquid Marine Buffer?

The liquid marine buffer is to keep your ph stable. Weather ho or low. The carbonate is for the coral growth and health. Your ph levels are very important to your corals growth and health as well. Through my experience use both as needed
