Ok, it appears that I jumped the gun a bit too quick in ordering the vivi nova tank. Seems the V2 is outdated already by at least two revisions? (v2.5 and v3?) Problem now is, I need some new coils for my tank, and finally found a place that had them in stock, but they were v3 coils. They are much shorter than the v2 I have, do not seal or screw down far enough it seems to work. Does anyone know of a place that still sells the longer v2 replacement coils? I'd hate to find my tank obsolete already.
