dosing help

I appreciate the advice. I had been relying on water changes to keep things in check and everything was fine. But I discovered that IO salt was only giving me a mag level of 1250 and calc of 380. My goal for this tank is a clam and some sps so I was hoping to bring it up to a safer level.

Maybe I should just look at switching salt brands.

Are those of you who use IO salt having to dose daily or are water changes alone enough?

Go have a read of Chemasters thread (http://canreef.com/vbulletin/showthread.php?t=26590 on how he accomplishes decent levels with IO salt.

Thanks for the link! I will try it out.

I've never really taken the time to read how each param affects the other. I just bring levels up to ideal with my chems and keep guessing with my doses in small increments starting from a very small amount and test at the end of the week. Then I adjust.

Dosing daily should be the most stable method. I currently in my 34g bring mag up to normal in my Reef Crystals (other 2 levels are higher than target) and dose alk and calcium with a syringe in set amounts. Once in the morning (an hour between each) and once in the evening (also an hour inbetween).

I have been slowly increasing levels that I dose every week or two as demand ramps up so usually I'm just a little off with alk and calcium since I'm trying to guess the right dose but that amount changes as demand rises too. I'm very close and some weeks I get the exact targets when I test.

What does your Reef Crystals salt test at for Mg before bringing up the levels ?

1100 I think.

All I know is I have to toss 100mL of the BRS magnesium solution into a 5g pail of new water. My target is 1400.
