cloudy water

Pulled water out and added fresh to lower salinity

Hmmmm... Have you checked the salinity?

 

[Convict2161]

Remember stability is more important. Once your salinity starts to swing up and down, down and up... That's when things can happen. Not good things.

My hydrometer is reading 1.022 and according to aquatic critter guy my hydrometer is off by 4

How do we know his isn't off? Hmmmmm????

 

[kwandrsn]

He said it was 1.030 and I was getting 1.026 so I got it, down to 1.022 on my hydrometer so it should actually be 1.026

 

[kwandrsn]

He checked water from one of his tanks then rechecked mine. He was, using a refractometer

I'd get another one if you can't get a refractometer. Then compare the two you own and see what you get. IMSO right now your playing the guessing game between to pieces of equipment that are known for there inaccuracies

I almost bought one of those temp a hydrometer things that floats in the water

At this point it's a guessing game. That's just my opinion.

 

[kwandrsn]

Yeah I will figure something out.

Imo I would trust the guy with the refractometer. It would be good to invest in one yourself. I may take my own advise on that one. My hydrometer seem to be almost the same as what they get at aquatic critter. I believe mine reads 1 lower than what they get on the refractometer.

 

[kwandrsn]

Yeah I found refractometer on Ebay for $23 but how do you know they are correct? How do you calibrate

 

[kwandrsn]

Will a 23$ refractometer work?
Do, you just calibrate it with distilled water?

I have never used one. Anyone else have this answer?

 

[kwandrsn]

I can get one for $23 or one with a 3.6ml vial of 35ppt salinity solution for $29 should I spend the extra 6 bucks or does distilled water calibrate it good enough

 

[kwandrsn]

Ok bought one cost $22.17 shipping included

Looks like distilled water will work.

 

[kwandrsn]

Yeah what I'll do is take it to ac and see if they will calibrate it for me

Good idea! They are very helpful and knowledgeable.

 

[kwandrsn]

Yeah I'm assuming a salinity solution would give you more accurate calibration I'm just wondering what the difference would be between distilled calibration and solution calibration
