Assume you mean .4????

Thanks-by what you posted -I am dosing about 22x more than that! So how much are you dosing now? And what was PO4 starting point & current? Maybe I will reboot lanth but I want to see it basically gone from the system before I do so.

Interesting combo -makes sense - As for chaetogro-says a lot about what chaeto actually does to trace elements given its..concentrations..

@Thales -what would be your recommended starting dose? I had started 40:1 -perhaps it needs to be even more diluted? Ironically when I think about it I had actual split the doses over a 24 hr period -the amt in the ICP was around two. But at some point I also really changed the feeding...

I’ll have to look that up!

Bahaha

Either way -I am not going to spend time debugging it as there really isn’t a viable way of testing for it except with a lot of ICP tests. All my fish are fine and corals are ok except the acros for now.. Back to other po4 reduction methods

ICP showed up with some heavy metals too so I am sure that plays a role too. Hard to discern when there is more than variable at play. The heavy metals come from overdose on trace elements so that is easy to discern and remediate. The fun never stops!

Supposedly it’s the yellow tangs that are sensitive.

It’s high enough to impact corals though-

I have some no longer chemicals -before I dumped them so if anyone wanted them. Pick up Oakland or I can get them to swap with name on it somehow 1) TropicMarin balling B -2.2 lbs 2) carbo calcium -800 mg - opened but barely used. 3) two reagent A bottles -not sure how I ended up with...

I had liked lanth in only that you couid lock in the dose and keep whatever PO4 level you wanted-with GFO -it seemed effective and then maybe too low.. and a couple times nearly stripped them out… With carbon dosing -could also keep PO4 stable -just not low enough..but based on Charles molar...

Well my experiment with lanth comes to an end -with the most recent ICP test -it came back at…wait for it…11! Least didn’t kill my fish and most of my corals are doing ok. I will simply go back to carbon dosing -

Def an idea to consider -although they don’t seem cheap! Things I have observed 1) cabinet enclosed -no opening -temp increases -low PH 2) cabinet open - temp lower -no change in PH 3) cabinet open with fan -really drops the temp and increases PH More to consider..

Oof. Sometimes I think it really is difficult to get the chemistry right sometimes

You are reading that correctly. I have had used a fan in the past with a cabinet open that def boosts the PH in addition to the main quest to reduce temp. This was just to see if there was a real difference in CO2 with that door open even with the circulation pump doing a pretty good job...

Interesting enough I had taken off one of the cabinet doors up top off to allow more airflow. The goal was to see if PH would rise with additional airflow. Interestingly not -which maybe dictates water chiller over fans..

Does anyone have an avast stirrer? If so -does your stirrer drip during periods when you are not dosing-or if you resolved -how so? I have one currently not in use but I took it out of commission due to this issue. But with low PH issues I am rethinking that..but that drip.. TIA.

Ditto

Pretty cool.
