My fish started gasping at the surfece at the moment that i added AlguMiN in said on the instruciton that the tratement last for 3-4 weeks and it is a mild biological treatment that contains humic substances as a natural anti-algae agent when used correctly, it is harmless to fish, plants and micro-organismshey say it contains.
They say 5ml for 10L I added in my 250l aquarium 100ml(enouht for 200L).The solution contains 0.13g simazine

What i had observed is that:The temperature in the aquarium has rouse up by 3oC(from 29 to 32) so the temperature might be a problem
The fish gasp at the surface only at evening buti have any plants so at evening shoul be alot of oxigen in the water

What i have done: Stop the CO2
Change water every day 4%(10L;2.5G)
At night let the air pump with an air stone on

The aquarium is ok on nitrites and nitrates and i had no problems with amonia
I'll try to cool the water a little to see what happends.
I added the solution 6 days ago

Any advice will be apreciated.

What sort of algae are you battling? From experience the additives to remove algae from a tank do much more damage than they are worth. In the end its best to figure out what the cause of the algae is so you can stop it from growing naturally. It will make plants and fish happier.

Do you check your pH? If you have stopped addition of c02 then maybe your pH has swung.

Before you criticize someone walk a mile in their shoes. That way you're a mile away and you have their shoes.

Temperature will definitely be a problem as oxygen levels decrease in warmer temperatures. Combine the warmer temperatures with CO2 injection and you may have a substantial problem.

I would cease the CO2 injection as I am recommending that you provide some aeration to the aquarium or surface water movement to increase oxygen in the water. The aeration or surface water movement would naturally dissipate CO2.

Not knowing the typres of fish that you keep, can you reduce the water temp to 29C or below?

I don't have a PH test at the moment.
I have 2 blue gouramy; 11 cory; 2 megalechis catfish;algae eaters; neon tetra,black widow,livebreeders, callistus.
I don't think it is CO2 because my aquarium has almost 3w/g so after a few hours with no CO2 addition i should have my water full of O2.
I'm trying to combat blue algae and spot algae witch are all over the cryptocorynes and marsilea and anubias nana
