I'm new to the site. My son has 3 Bettas. All seem to have beginnings of fin rot. I can only imagine, since the water they come in is so little and dirty. And the guy at the store said, for our 1/2 gal vases, "change the water 1/week". UGH!
What shall we do? We started the Maracyn-Two but now I hear it doesn't do much.
Also, how much sea salt shall I add to that small of a vase? I haven't done anything with the Ph etc. as I didn't know to. Temp is fine. They are in a room with light on the low side. I had them in a brightly filtered bathroom but read not to put them there....I'm so confused! We really love these little guys and want to do the best for them. Could someone starts us from the beginning and get us going? I'm going to do a water change and will be back shortly.
Thank you all!!!!!
