iv been using a refractometer on my tanks since i started.. almost a year..
but i have just upgraded to a better one. and i dont know how to read this one.. here are some pic..not the best.. of what it looks like on the scale.
the other pic is not my refractometer but looks just like it,with 3 small lines 1 med size line and 3 small lines between 1.020 and 1.030
but my problem is that there is not 10 lines between 1.020 and 1.030. so water from my tank is coming up as 2 lines under 1.030 , so what is that??
and between 1.020 and 1.030 there are small lines and one bigger line about half way between the two.. is that bigger line 1.025???
i have a 55 gal fowlr with 25 gal sump, i want to keep it at 1.025 is that a good idea?? or no?? if 1.025 is a good range to keep it at were is the 1.025 mark on this thing?? thank you in advance.
