Timing of ozone usage (vs. dosing major and minor elements)
Learned something new yesterday from Christoph / Oceamo in the German-speaking podcast:
Not relevant for most here since not many, if any use ozone, so more a note for me.
I recently reduced ozone dosing from 24/7 to 10 minutes every hour in the first 10 minutes of each hour, due to low/0 SAK values. This increased my SAK value to 1 and my skimmer also seems to perform better now. The main reason for my reduction in ozone usage.
Christoph said that trace element dosing should not overlap with ozone dosing as ozone would try to oxidize these elements (known bromate concern, but apparantly not limited to bromine only).
I struggle with maintaining certain key elements such as Nickel, Vanadium, Copper, and Zinc, which coincidentally are being dosed hourly while the hourly 10 minute ozone dosing occurs.
I have now moved the ozone schedule so that it would not conincide with any trace element dosing. However, I might need to move ozone dosing further away (several hours) from any trace element dosing, as he recommended, which will require additional dosing schedule changes.
Will see in the next ICP in late April if any impact.
