Went to 14.2 dKH from what level? Turbo calcium shouldn't raise alkalinity.

hi,
it went up from 10.5/11
i did read this article many times:)))
should i cut dount on co2 or add more ca cloride?

thankx

I can't think why the alkalinity would have risen from the turbo calcium.

What is the calcium now?

Maybe the CaCO3/CO2 reactor is just driving too much into the system, and backing off on the CO2 bubble rate is in order.

[MSHUR]

calcium is 370-380 right now
i will cut down co2 bubbles and will let stay like it for 2-3 days

thankx,Randy

That sounds good. Also, with the calcium below 400 ppm, keep adding the turbo calcium when you drop back on the CO2.
