wayneb Posted April 30, 2010 Share Posted April 30, 2010 Nearly crashed my tank- Was relying on the "cheap" plastic Red Sea Hydrometer for my salinity readings. Even after topping off a few times with RO water, the meter showed it was always between 1.023-1.025. Mixed up some new saltwater to do a water change and had 3-4 readings of 1.025 so figured I was good to go. Luckily I decided first to get the tank water checked at our local Petco first. It read 1.018 (they used two different meters and both read the same). Got a sample of the salt water I mixed up and they read it as 1.020. Can anyone suggest a good, mid price range refractometer and a source on where to buy it, either locally or on-line? I had talked to Shane and tried out a couple he used. I was going to have him order me one from his vendor, but he called yesterday and said the vendor now has a new "minimum order" amount and it would probably be a few weeks before he would be able to order from them.
