My two Clown loach's have Ick, I've tried Malachite Green but don't see much improvement, I wanna try raiseing the temp & adding marine salt to the tank, my question is how much salt should I add? Tank is 75gls any input will help,,,
Thx, I will try 1 tsp per gallon, I just did a 40% water change, gonna add the salt when the debri settles,,,Bump the temp up to 89degrees. A degree per hour. Then salt is usually 1tsp per gallon. I know some members have done it with cl's and no issues. The other option is to do 1 tsp per 10g and is less tolerant. If the cls act funny that do a water change asap.
The bag of salt I got is 2.8lbs I dissolved almost 1third of the bag & added it yesterday, just added a touch more now, I have a good amount left, I will add the rest over the next few days, do you think I should preform water changes as I add the rest of the salt or just let it be?Ick is killed at a salinity of 3ppt (parts per thousand) below that concentration number (even slightly) and enough ick individuals can survive to reinfect the tank.
A 75 gallon tank will need 2.5 lbs of salt to reach 3ppt.
As Coryloach said, add gradually.
How long did you wait to see improvement? Ick is not killed overnight, or in 2 or 3 days. The (each) protozoa needs to complete its entire life cycle to be eradicated (more than 1 stage), this can sometimes take over a week, sometimes more.
