May I use this when cleaning an aquarium weekly instead of using stress enzyme?

Yes, I use it every time I clean the aquarium. I usually put half the required amount directly into the filter (once I've clean it) and the rest in the tank itself. Its perfect for introducing new fish to the aquarium as well as when cleaning it out.

How much quick start should i use when doing a water change? should i use dosage vs total water in the tank (30l) or water i am changing (7.5l) thx

As it's a partial water change; not servicing the filter itself; stick with the amount for the total capacity of the tank will be adequate. A little over will do no harm either, adding a little now & then will keep both the tank & filter up with its ideal bacteria levels to process the muck etc. Some with more money then sense will dump the whole bottle regardless.

Do you use this every time you change water

Hi yes you do . I mix about 10 caps in to cold water half filled bucket and stair it about leave it till water change the next day . Hope this helps you .
