converting tropical tank into brackish

[TheDragonLord]

should i stagger the addition of salt into 2 parts a week apart so as not to kill off all the bacteria or do you not think that will be enough? i only need it about 1.005

i currently have a few guppies in there keeping the filter going but i'll remove them when i add the puffer

What puffer?

Increase your SG no more than 0.002/week as to not kill your bacteria.

Depending on what size puffer you're adding, a few guppies may not produce enough bioload to support it.

I believe he's getting an F8 for a 16g.

yea its a figure 8 puffer for a 15 US gallon tank (54 litres)

i had a betta in the tank with the oldest of the guppys and ~40 shrimp, but the shrimp died not cheap shrimp either so i sold the fighter and chucked in 5 more guppy fry, just to keep a low level of bacteria going
