how much salt for 1 ft tank ?

Can any one help me to answer the few question below ?

Thinking of put in some salt, but no confidence that how much to put. Currently, only put very little salt, i.e. 1/4 spoon for the 1ft tank.

Is it a must to add salt to the guppy tank ?

How much salt to add to a 1 ft tanks ? ( about 20 liters tank, 30 x 30 x20 cm)
1 tea spoon for 20 liters ? normally, how big is the tea spoon size ? 5ml ? 10 ml ?

Is it ok or necessary to put a small placo in the tank together with the guppy ?

Is the placo consider scaleless fish, can it tarhan the salt ? I read from somewhere that scaleless fish cannot put salt ?

Thanks.

I add a bit (2 to 3 small pieces) into the tank.
Salt is not necessary for any tanks. Hence i dose just a bit.
But salt can help to reduce nitrite level if its too high.
Pleco is fine with guppies. I keep bristlenose plecos with my guppies.

pleco can tahan salt.
but pleco grow very fast.
my normal pleco brought home abt 1inch 2months later 3-4inch already

it's not necessary to put salt into the tank, salt is only used when your guppy is unwell. yeah plecos can take the salt.

I have never put salt in the tank for my guppy. I think guppy hobbist also seldom do that. Maybe when they are sick, occassionally some might put
salt.

Thanks for all bro for the advise.

Well before you add any thing into you tank, ask yourself this, "What am I adding and what is the purpose for it?" If you cannot find the purpose to it, I suggest you don't add any addictives into your tank unnecessary.

would it be a good idea to add a nip of salt after introducing a new fish into the tank?

for me i am also using a 1ft tank i do add salt to my tank de erm for me 100% 3/4 teaspoon of salt then weekly wc 50% is abt afew small pcs of salt nor about there slowly see yourself nor

those that no filter in my tank i i use my main 1ft water then top up then maybe add 1 -2 pcs each wc is about 20-40%

P.s it may work for me may not work for you up to you to follow haha
