While In My Local Lfs

[Johng89]

While in a few of my local LFS I have noticed that the staff add a blue liquid into teh tanks when carrying out water changes

Just wondered
What is it ?

What does it Do ?

Cheers

it may just be water conditioner

Waterlife make one beginning with 'h' I think it's something like haloex, anyway that is blue in colour

Could it be methylene blue? Maybe they have had a disease, hence the waterchange.

Tetras Aquasafe is also blue.
