hi

i was sold a nitrate removal sachet from the fish shop which did seem
to work, but it says in the box that you need to recharge the sachet,
bu pouring salt water over the bag for one hour and then repeating this
procedure for two hours. is this correct? how can it be done? are there
any simpler ways to keep nitrate levels safe?

That's sounds a bit too labour intensive to me.

I have the instructions for one of these pouches:
"Dissolve 80g of aquarium salt in 240ml of warm tap water (48C) and soak
the pouch for two hours then rinse lightly in tap water. Pouch is now
ready to use"
