Help and Advice

Hi everyone, soon be weekend, just done a complete cleanout and 20% water change to try and get rid of my algae problem.

Bought my usual salt water mix today from the Lfs and questioned the nitrate level of the water i was buying.

He informed me his water never really gets below 10!!!!!!!!

So if that is the case how the flock can mine ever be lower than 10???

I asked why it wasn't at 0 and he said because he makes so much it is impossible to improve on 10, which means if I do my water...
