Lower your temp to 77F add as much C02 as it is possible get 250 mil of excel and dose it daily until finish. You already have shrimps, see if you can get some baby Crossochelius siamensis (they are the best) and soon you will be back on business again. It takes time and effort to destroy this pest so be patient. Also make sure you have good water circulation a 55 gallon tank can be difficult! by doing this you will make sure the Co2 it's well distributed.
