I am a proud owner of a python vac pump hose... the Python...anyhow,
I got this question going around my head, and been the fact that my first major water change is approaching fast.. there is no question on how it works, it simple and fast..and I love it.
But here is my question.
When do you add/ or how do you add the water declor/dechlro/ammo to the water??? Before you had the new fresh water??... as you add the new fresh water???...
what will the effects be on fish or good bacteria colonies be if the treatment of the water is applied after / before the new water hits the aquarium???!!!
Thank you all for the answer to probably soo an ovious question!!
