BIG TROUBLE!! Need advice please.

[doch]

Yes, I do use RODI. This is the first time that I have.

I think that I may have found the Mg culprit. I had a bucket of 2Ocean sitting around waiting for changes.... I was at the bottom of the bucket, and today I did yet another water change, and tested the Mg before putting the tank online. 1850! Seems that is the Mg problem. I wasn't smart enough to test the Kh before putting it online, so who knows about that. For the record... yes, yes, I know... roll, shake and disturb salt before use. I have learned this the hard way. Crap. And lots of it.

This all said, who knows... it's a semi old Mg test kit, maybe it's out? I get a new one tomorrow so we'll see.

So, I went onto BRS and used their reef calculator... turns out that I was using too little GFO, so I upped that and the carbon. I dosed a little Ca so we'll see what that does... hopefully bring the Kh down.

One question though... talking to buddy tonight, I was told that dosing for Alk will drop the pH... is this right? Everytime I dose soda ash my pH spikes... I think. I haven't paid attention in a while, but I thought that was the case.


Anyways kids, thanks for the inputs. Wish me luck in saving my little box of ocean!
