Dechlorinator Directly Into New Tank?

[eaglesaquarium]

Once cycled and fish in tank then you are going to need to add the dechlorinator to the bucket during water changes, not the tank. Otherwise you may affect your filter bacteria.

I'm sorry, but that just isn't true. During a water change, the filter should be turned off. The dechlorinator works instantly when it comes into contact with the chlorine. Add enough for the ENTIRE VOLUME OF THE TANK, not just the amount that you are replacing, and turn the filter back on after the tank is full. I've been doing it like that for quite some time, without any issue, as have many others here.


As far as the cycling for a smaller tank... Aqua Tom is exactly right.

Good to know. Might make life a wee bit easier. I suppose the only thing is having to use more dechlorinator for the size of the tank. Is fine if using prime.

Exactly, but if you have a lot of tanks, or if you have big tanks, it makes it much easier to refill with a hose.
