im sorry about the measurements. i live in japan and well, the tanks dont say gallons. oh and the salt is in japanese so i dont know how much to add. its sealife salt. the tank is for three dwarf puffers for now.

Edit:
well, besides DPs, whatabout a ceylon? im planning to do some maintinence on my 30 gallon which it is currently in. im thinking of putting my ceylon in it for about a month. how much salt should i put in it

Dwarf puffers aren't brackish puffers, so you shouldn't have to add any salt! Check the Puffer Pedia just to make sure you actually have Dwarf Puffers.

Definately no ssalt at all for DPs. Good thing you found us & asked 1st! That's how I killed my 1st 3 DPs, thinking they were brackish.

If you have a Ceylon, then you should invest in a Hydrometer. They measure the Specific Gravity (SG) of the water, which will tell you how much salt you have in it. I usually use 1/4 cup per 2 gallons of water to get an SG of about 1.008.

Look in the Puffer Pedia for information about the Ceylon. As they get older (and larger) they require higher and higher salinity in the water (ie. higher SG). I don't have a Ceylon, so you might want to wait for someone with personal experience to help you out with this.
