Thanks for all that info. Those are for Mollies right? If I raise the pH is it going to be a problem for the Platty and the Tetras?

Ok, done. Will keep you posted. Thanks a bunch everyone.

@Whitecloud09 Ok sure, I'll go get something to test the ammonia. I am probably learning all this the hard way hahaha. I do have Nutrafin Plus and Nutrafin Cycle is this the same thing as the Seachem prime conditionner?

Thanks for your input... I have 1 Molly, 1 Mickey Mouse Platty and 3 Neon Tetras. I don't see any aggressivity between any fishes. The Molly is super duper friendly with the Mickey Mouse Platty. Always together. Should I use any medication? Or just water changes? It's a new world for me. Thanks for you help. Huummm I will see if I can get real plants instead but I don't have lots of substrate and don't plan do add more. Any plants in mind? I do have some API pH up, but I am so afraid to use that, any guidelines? And for the hardness, each time I do a water change, it goes down again. It seems impossible to reach a higher level... Or I just don't know how to do it properly?

I have this little Molly since 2 months now. There's some weird spots on top of her head and around the eyes since the beginning. I am wondering if I should do something. She's really active, eats well, but I feel there's something... Other fishes are ok. Nitrate: 10 Nitrite: 1 Cl2: 0 Hardness: 25 Alkalinity: 40 Carbonate: between 0-40 pH: between 6.4-6.8 Any help is welcome :)
