Well as most of you know I been around for a few years and have been doing SW
for several years.. Well this is the first time I'm sitting here scratching my head totally dumbfounded..
I woke up and checked my tank as I do every morning.. But this morning I awoke to a tragedy.. All of my Nass. snails as well as all my others types of snails were dead.. Mind you, the bodies were still inside the shells, so I don't believe any other critter could have been the culprit.. Specially since I haven't added anything in over 2 years. The fish are fine and show no signs of distress, least not yet.. I have a pair of Cleaner shrimp which are fine and some stars and an Urchin and a few hermits as well as my corals.. all seem to be doing ok so far..
Checked the tank specs.. all is fine cept for some traces of Nitrates 20ppm.. I can't see that being an issue..
I'm concerned as to what the problem may be.. Could my sand bed finally be going bad after 5-6 years? My Sand bed is around 4 inches. What could it be?
This is my small tank btw.. Its a 46 gal
. Bow front.. I'd move the stuff to another tank but don't wanna risk whatever it is carrying over.. I'd appreciate some help on the subject.. TIA
