| Re: red sea hydrometer
I agree with Daniel. Being in the Business that is why I try to educate. @ my shop if some one comes in & doesnt have a refractometer & cant afford one I give hyrometers away. They are very inaccurate it the point that is trying to be made if you are happy with the red sea ( which I will give you this red seas is the best on the market) But still not 100% accurate everytime. |
