newbie question: dosing time-lite off or on??
 

i 'm dosing tlf part a & b. thx every1.

I have no idea what you just said. ;)

P.S. If you give people more information such as what the product is (full name, not abbreviated) and what it is supposed to do, we might be able to help you more... I personally dose in the afternoon, my lights come on at noon, and I only dose Tailored Aquatics Calcium +, and Magnesium. I don't dose alk, since I do a 25% water change every week (and the Instant Ocean I use tends to mix up with pretty high alk). I don't know if this helps you at all :lol:

I usually dose my 2 part just before the lights go on in the morning

If you can, dose the Ca in the morning and the Alk round lights out or just after. You shouldn't dose together in case of a reaction occurring.

Dosing Alk at night can also help counteract pH swing, if you have any.

I agree with shrimpchips. For those doing daily dosing of calcium and alkalinity, dose the calcium in the morning before lights on, and alk at night after lights off for best results.
