Just because you're not paying for water. Not really an advantage, just a matter of volume. A jar of the dry stuff lasts longer than a jar of the liquid. No other reason really.Jgoal55;205924 wrote: Really? Why do you prefer the dry? Just curious. I make my own RODI so I could use dry if there is an advantage. Do you mix it in to your top off or into your salt mix?

I mix it with RO/DI water in a cup to pour in. Never mix dry supplements or other chemicals with saltwater or tank water. Always add them to a volume (usually a couple or few cups) of RO/DI water. Otherwise, you risk causing precipitations and/or concentrations that can cause bad reactions. For example, adding calcium supplements directly can cause calcium precipitations that can chain-react and drop the pH of the water. There are exceptions, but if you just do it for all additives, you can't go wrong.
What do you call adding calcium, alk (I assume you use Sodium Bicarb or something similar), and magnesium if not "additives"?washowi;206053 wrote: Don't use additives at all....Just calcium and alk and magnesium once a week.

Even if you had only a 10g tank, you probably have at least 5g of water which is 640 ounces. 1 cup of water would only dilute 5g of water 1.25%.Jgoal55;206196 wrote: true..i guess they do last longer...makes sense....when you add it to a cup of fresh RO though...and especially if you have a small tank...won't that mess with your salinity???
