If you calibrated your refractometer, I would go with that reading over the DeepSix
I agree.. I always found the Deep Six to read about 1.025 when the refractometer read about 1.029-1.030 I went with the refractometer.. I have seen several Deep Six meters off by the most that much.. When I was using my deep six I had it set at 1.024 and my tank was really 1.027-028 I lowered the SG
and everything seems to be doing better... I Checked another guys tank the other day and his deep six says 1.025 while my refractometer stated it was 1.030 I would go with the refractometer as if they are calibrated right they should be extremely accurate and would trust my investment on one.. Cant say the same about the deep six...
Will high salinity have side affects on snails? Like make them just lay around and not move much
It all depends on the actual snails.. Some might croak right away some might just be lazy some could go on as normal.. I would just lower it slowly and see how they react.. My guess is everything will act alot better in your tank..
