I've done the the third partial water change on my tank; the first with the vacuum system; it was not bad, just need a bit more skill, I reached the 30% level mark faster than I thought.
I added the dechlorinator ( Tetra Aquasafe Plus ) while filled up the tank with the vaccum system, I mean; the tap water got and the dechlorinator at same time, it was ok? or I must do it before add the water to the tank?
