Greg's 75g

Lots of updates ...

So, the wifey surprised me with a brand new Tunze ATO for the QT
I had no idea she was doing this when I bought Rich's used one
I sold his yesterday

Thanks Donna

Tues night I decided to start raising my Mg
I will start off by stating there is a possibility that my testing methods were off ....
Also, I should have waited a day after the WC before adding the Mg liquid

The end of a bucket of IO salt ....
NSW
11.5 Alk
520 + Ca ( I should have tossed the water at this point )
1250 Mg

DT
7 Alk
450 Ca
1250 Mg

I then did a 15+% WC and waited a couple hours
Next, I re-tested the DT
7.5 Alk
440 Ca ( ??? )
1250 Mg

As you can see, there is already a discrepancy in the Ca
NSW test must have been off, or minerals were interacting during testing as I tested the Ca 2 more times, and still read 440ppm

Next, I added enough liquid Mg to raise it by 100ppm
3 hours later, and I tested 1350 Mg

Now, here's where I deviated from advice and added another dose of liquid Mg
An hour later I tested the DT
6.5 Alk
500 Ca
1400 Mg

Again an hour and another retest
7.5 Alk
460 Ca
1400 Mg

Obviously at this point the Mg, Ca and Alk are trying to balance each other

Then, 2 days later ...
8.0 Alk
520 Ca
1350 Mg

pH and Sg have been stable the whole time
The only effects I have seen so far is one Turbo acting a bit lazy, and the Frogspawn has been remaining closed a bit longer than normal

I have just mixed 20g of NSW from a new bucket ( free T-shirt ) and will be doing a 15% WC soon as I feel the Ca is too high

I've also been doing WCs from the DT to the QT as ( I've mentioned before ) I am ready to start adding fishies to the DT

The Turbos and Strawberrys have been doing an OK job of keeping some sections of rock clean, but nothing huge

The Peppermints cleared out all but 1 or 2 Aiptasia
The timing is good as they will be getting leftover fish food very soon

Guess that's it for now
