Composition for destroying thread algae

Abstract

A composition of alkali carbonate peroxyhydrate in a quantity of 45 to 85% by weight relative to a total amount of the composition and an alkali hydrogen carbonate is provided for combating pathogenic germs and parasites in water of aquaculture, ponds, and aquariums; for destroying thread algae in water; for processing water. The addition of alkali hydrogen carbonate to alkali percarbonate peroxyhydrate stabilizes the alkali percarbonate peroxyhydrates relative to combustible materials. The alkali carbonate peroxyhydrate is preferably Na 2 CO 3 and xH 2 O 2 .

What is claimed is: 
     
         1 . A composition comprising an alkali carbonate peroxyhydrate and an alkali hydrogen carbonate, wherein the alkali carbonate peroxyhydrate is present in the composition in a quantity of more than 0% up to 85% by weight relative to the total amount of the composition. 
     
     
         2 . The composition of  claim 1 , wherein the alkali carbonate peroxyhydrate is Na 2 CO 3  and xH 2 O 2 . 
     
     
         3 . The composition of  claim 1 , wherein the alkali carbonate peroxyhydrate is 2 Na 2 CO 3 .3H 2 O 2  or a mixture of Na 2 CO 3  and H 2 O 2 . 
     
     
         4 . The composition of  claim 1 , wherein the alkali carbonate peroxyhydrate is present in the composition in a quantity of 45-85% by weight relative to the total amount of the composition. 
     
     
         5 . The composition of  claim 4 , wherein the alkali carbonate peroxyhydrate is present in the composition in a quantity of 74-82% by weight of the composition. 
     
     
         6 . The composition of  claim 1 , wherein the alkali hydrogen carbonate and the alkali percarbonate peroxyhydrate are present in the composition in a quantitative ratio of 15:85 to 55:45. 
     
     
         7 . The composition of  claim 1 , wherein the composition comprises 1-10% by weight of earth alkali peroxides. 
     
     
         8 . The composition of  claim 1 , further comprising 0.5-4% microorganisms. 
     
     
         9 . The composition of  claim 8 , wherein the microorganisms are selected from the group consisting of autotrophic and heterotrophic microorganisms. 
     
     
         10 . The composition of  claim 10 , wherein the microorganisms are selected from the group consisting of chemolithoautotrophic nitrifying microorganisms, heterotrophic nitrifying microorganisms, and combinations thereof. 
     
     
         11 . The composition of  claim 10 , wherein the chemolithoautotrophic nitrifying microorganisms are selected from the group consisting of ammonia oxidizing microorganisms and nitrite-oxidizing microorganisms. 
     
     
         12 . The composition of  claim 10 , wherein the heterotrophic nitrifying microorganisms are selected from the group consisting of fungi of the genera  Aspergillus, Penicillium,  and  Cephalosporium;  algae;  Arthrobacter  sp.;  Alcaligenes  sp.;  Nocordia  sp.;  Bacillus azotoformans; Sporosarcina psychrophila; Pseudomonas  sp.;  Paracocus  sp.; and combinations thereof. 
     
     
         13 . A method of combating pathogenic germs and parasites in the water of aquaculture, ponds, and aquariums, the method comprising:
 (a) providing a composition according to  claim 1 ; and   (b) adding the composition according to  claim 1  to the water.   
     
     
         14 . A method for destroying thread algae in water, the method comprising:
 (a) providing a composition according to  claim 1 ; and   (b) adding the composition according to  claim 1  to the water.   
     
     
         15 . A method for processing water, the method comprising:
 (a) providing a composition according to  claim 1 ; and   (b) adding the composition according to  claim 1  to the water.   
     
     
         16 . A method of stabilizing a composition comprising alkali percarbonate peroxyhydrate, the method comprising adding alkali hydrogen carbonate to alkali percarbonate peroxyhydrate.
