we have available sodium hypochlorite 15% liquid, and in a calcium-free version. or calcium hypochlorite 70% granules. I have no idea what the difference is:D

hi thanks for the response, so is calcium hypochlorite better than sodium hypochlorite? Do I use phosphoric acid to adjust the pH or does it bother me? Thanks

Hello, thanks for the response, it is true that a little light penetrates into the tank, unfortunately, the system is poorly designed, so it cannot be completely prevented. How did you end up solving it?

Should I buy hypochlorite with calcium or rather without? Does hypochlorite affect pH? Thanks

hi, thanks for the response, can I use sodium hypochlorite from the beginning on the shutters? I read that it should not be mixed with any acid, but I use phosphoric acid to adjust the pH. is it also suitable as a system disinfectant? In what proportion. Thanks

I also thought that it could be from a friend of mine, but I have two systems and in one only one plant died, the others are fine. In the second system, it spread to everyone. I use Metrop mr1/2 callgren, the pH is the input water, otherwise I lower the pH to 5.6-6.

Hi, my name is George, I've had a problem the last two laps. My setup is: aeroflo, inlet water 7.6 ph and 0.7 ec (because it's terrible, it can't be done otherwise), chill keeps the temperature of the solution at max 22c, room temperature 24-28c. I put the same genetics every time, my friend...
