that is a very low air change rate, it should be about once every hour.
if you look a tight home has a natural air change rate going down to
0.33 /hour and they need mechanical ventilation to bring them up to that once per hour range.

haahaa you're right, I did the math in my head as cfh, not cfm! It can turn our house over 1.7 - 6.7x per hour depending on settings.

Curious on your cayno issue and see if it improves any with the new salt, some have been saying as it a form of carbon dosing it has made it worse.

I just did another ~20g with the ™ Bio-active salt so time will tell. But honestly the tank is looking swell. The sand and rocks have cleaned up ~95%. I checked my RODI though and the TDS meter said 89! I need to start checking my system again and sort that issue out. Maybe it was just having a bad day :)

Don't forget to check calibration on the TDS meter while you're at it. Good news the cyano situation is looking up though. What all did you do to help eliminate it?

Things I changed were:

Reduced Mitras light output from 60% to 50% and dropped the 4400K & 6500K spectrums down to 30% (from as high as 70% at noon).

Took bio-pellet reactor completely offline.

Increased flow to GFO & GAC (did not add or replace media, just increased flow).

Did ~20g water change (did another 20g last night but that wouldn't count).

Recently dropped the temperature from 26.0 to 25.7 celsius (may not have contributed since it was done recently).

Started feeding less than a full PE Mysis cube, but added cycploeeze to the mix (Mysis always thawed and rinsed before feeding)/

I recently turned the lights back to the original 60% total power output and restored the white channels to normal. We will see if I get a resurgence of algae. Colby had come over about 10 days back and he had a tough time identifying the algae. He said it lied somewhere between cyano and diatoms. Mindy, I will go and calibrate the meter right now and test again :)

Cheers,

I calibrated the TDS meter…. back down to 17 ppm lol!

:lol: That's still 17 ppm too high! ;)

I know lol. Colby was out of DI resin last couple times I stopped by :)

If I had 17 ppm coming out of the DI I would be replacing the RO membrane. You will burn through DI very fast with that much going into it.
