So my snails are spawning like crazy right now. I cannot believe the amount of stuff coming out of them. If I recall correctly, this can cause a drop in oxygen or an ammonia spike or something like that. Is that correct? I suppose the solution as in 99% of cases is a water change if so. Please let me know if I need to be concerned about anything. I have a 30 gallon tank so the relative small size worries me. Thanks for the help.
