Trident finally settled down after blowing out the inlet lines. It gave me an Alk reading of 13+ vs Hanna.

Got some frags from a friend of mine — wish I can grow them out!

Looking great!

Been playing with the Avast K2 to boost pH — hope SPS frags will take off.

You dosing the kalk or running it off ATO? Hmm

30gal reservoir -> Tunze ATO -> Avast K2 -> sump. I've just dumped 4 cups into the K2 this morning since I was depleting kalk every week.

This is my K2 next to the sump

Nice, you have the consumption to use kalk for sure!

Uh oh — looks like we’re climbing too high? CaRx is already off so hope this will settle. ATO will cut off when I hit 10dKH though.

Now we’re smoking at 8.42 — I might dose soda ash at night to flatten out the pH curve.

Been trying to raise my Nitrate up from 5’ish. The sulfur denitrator is working too well so I’ve increased the flow rate to now running at -30mV to slow down denitrification. NO3 is now in the teens so hopefully some mushrooms will be happier?

I think we’ve hit a sweet spot — I’m happy with this so far, assume that it’s close to accurate. Now we’re on autopilot.

Have any progression shots of your sticks?
