hydrometer reading PLEAS HELP!!!

[Wildiana]

currently i have a FW tank, looking into converting into BW, i understand the 0.002 per week, however my level are so low that my hydrometer doesn't read any salt, i put 1Tbs for 10g as instructed, but still no reading.

so i bough a pond salt kit. it reads that i have 0.12% and to add 1CUP PER 100GAL.!!! i have a 20G long, i have a bucke which i filled with 1g water, and added 2tbs, that will be for about 20g...BUT i scared to put it in as it might be to much to fast.


PLEASE HELP!!!!

Not sure what pond salt is for, but you need marine salt for BW. It takes around a cup of salt/5g to raise the SG .005, so you'll need roughly around 1 3/4 cups to raise it to 1.002.

Thanks

the salt water kit was just a tester not salt.

now, will this hurt my fish that i have in there now?

2 platies
1 guppy
1 ballon molly
1 red tail shark
1 silver tip shark

The only true BW fish you have are the molly & silver tip shark. Livebearers do appreciate a little salt (aquarium salt), but the red tail shark will not. To measure BW salinity levels, you must use a hydrometer.
