As some of you know, my betta Alpha is in a bit of a pickle and since there is no filter and I cannot do water changes, I need to find a good ammonia remover fast! I've been using Prime, but I'm all but out and I'm going to Petco to get some ammonia remover, but I'm low on cash and Prime is too expensive ($7 for the smallest bottle!!!) I think Tetra AmmoniaSafe or API Ammo Lock are the best options, but which is better? I really need the help
