(1)Analyze the contents of free H₂SO₄ , SnSO₄ and total acid value daily, Every additional  1Kg of SnSO₄ at the same time add 0.5kg~1kg of BY-C11C.
(2)Add purified water slowly with agitation, so as to prevent the local hydrolysis of SnSO₄ which may cause the bath solution becoming turbid. 
(3) After long period of production, there will be white sediment formed in the bottom of  the tank that should be cleaned by filtration or decantation.
