Or you could just slowly measure what it takes to make 1gal . I've done it for 5gal.. I just quickly add it and it is always bang on.

Takes some patience at first but easy enough to do.

1 tsp changes your SG of 1 gallon from 1.019 to 1.027?
Is that what your saying?
Sounds like a pretty big swing for one little tsp.
I suspect one of your hydrometer readings was erroneous.
I suggest you try again.
Like some other members are saying here, it can't be that difficult to figure out. Just keep adding small amounts of salt, and recording how much you add, until you get the SG you want. Then, whenever you make a new batch just add the amount that you determined is required for 1 gallon.
I'm sorry, but I just don't understand the problem here. :confused:

Cheers,

Are you rinsing your hydrometer thoroughly in freshwater before every reading you take?

Borrow or buy a refractometer. If someone nearby has one, calibrate your hydrometer with their refracto because you'll probably find that its off by quite a bit. Friend of mine had 3 and all her hydrometers were pieces of cr@p that ended up crashing her tank :evil: Now she's got a refractometer like mine. Works great & worth the investment ($65 at J&L or OA).

Yes I rinse out the hydrometer. I 'm not saying I can't do it, it would just be easier to batch mix the water, and dip into it as needed. As my post asked, does anyone do this( with success)
I have not tried putting a lid on the bucket, and I also keep it at 78deg with a power head to mix. So i'll try to get a lid and not heat it. The whole idea was to be able to quickly dip into a pail and have a consistant SG, and temp.

Re: batch water mixing???
 

Sorry. I'm lost. I'm not sure what you want. :confused:

you can do it for a few days.. but I don't see it being worth using after about 1 week.

I think I'm going to have to agree with you Chad. Back to mixing 1g at a time.

annyone have a mixing ratio for salt? would be easier to mix..i'm mixing up a 5 g bucket of RO right now...using reef crystals

I think it depends on the salt brand you use and the end result you want.
Does the packaging on your salt say?
Instant Ocean recommends 1.5 lbs per 5 gal. to yield 1.022 SG.
