Patience, patience, patience !!! The tank will clear. Get some salt, a 50lb. mix bout $15(Kent at AD). a small power head Maxijet bout $15, 5 5 gal buckets with lids from Lowes or HD bout $15, I will give you my old hydromitor free until you can aford a refractometer and mix your own water you will be saving .75 cents a gallon x 25 gallons(5 5 gal buckets) = $18.75 plus gas for lets trips to LFS. It will pay for itself in no time. Only mix 5 gal at a time though and save the rest for top off and more water changes.
