I keep losing snails on a steady basis..... I find them in the morning upside down and put them against the glass.... sometimes they'll climb back up and do it again... and sometimes they're already dead...I've got turbos and redfoots... it's been mostly the turbo's lately... I have alot of other inverts and they seem to be doing fine... PH, Temp etc are all good.... my nitrates have been giving me trouble and are probably around 30ppm right now.... but the rest of the inverts are doing well... any ideas ???????
