When was the last time you did a WC? 50 ppm for NO3 is very high. Try doing a 25% WC and give it a few hours. Also what are your results for ammonia (NH3)?

my ammonia (NH3) is0,0 mg/l lost two last night but my molly as given birth to four babies. my local shop has given me some Interpet anti internal bacteria to use
will do a water chang tonight of 25%.
any more help will be helpfull.

You don't need antibacterial chemicals, you need to reduce the nitrates in the tank. Did you do the water change?

thank you for you time in replying.

25 is so much more tolerable. I would change another 10-20% tonight. Keep testing daily and try to keep it at 25 or under.
