Well, my dosing manually might have been a bit hit and miss, so hoping to get my doser on line today and run for a month and re-evaluate.

Ok, that's fair.

Following along . Going thru same thing .
Excuse my ignorance - what are MI's ?

Forget it - moorish idol.
I'm adding microbacter7 also . Started vinegar 2 weeks ago . & things are turning brown. Hoping it will turn around . No3 is high , so doing extra water changes. Time will tell .
Good luck

Oddly, the time I used MB7, I had a huge cyano outbreak. Gave up on that. Water changes aren't helping me a lot either, last week, NO3 at 10, did a 50% water change, this week NO3 at 20+.

Wow, I must be overkilling mine. 70mL a day on a 90g. Granted, I have heavy stocking but that's way over what everyone's using.

Any update Brad?

Ya, I think carbon dosing is stoopid.

+1

Yeah, really don't get why people bother with dosing carbon. I tried it once many years ago, and decided very quickly this was going to be too much work (and attention). Got a bio pellet reactor then and couldn't be simpler. Just add some bio pellets about once a year (went a year and half last time) and forget. N03 consistently stays near zero until bio pellets run out.

And no extra pump with mine. I have a T off my return line that runs through my chiller, and return from that goes through my bio pellet reactor.
