High Nitrate Levels.. How do i reduce?

oh my gosh! same here! but its been like that for a year. just change it regularly and all ur fish should be fine. do not put goldfish i there though. they will catch ick and spread it around because goldfish are so prone to ick in tropical water conditions especially. i have a 50 gallon freshwater with a bala shark,striped raphael cat,african fetherfin cat,black ghost knife, and an angel fish. im always stresses cause whenever i go away i always think im gonna come home to a bunch of nitrate burned fish.the algae is always growing. i have a plant to. it like does nothing. i have a rock formation and its faint to. my nitrate levls currently sit around 160mm just like urs... i think the only solution is to buy a new tank and if theres no fish like carrying some sort of microscopic thing tostart algae some how then the problem goes way. i had 3 dwarf gouramis in my 50g but i got a 48.2g and i put them in there just because. they all died but i put fish from my 10g in there and that tank now stays perfe.ctly clean. i think its just the tank. theres no way ill be able to buy a new one though... life tough.
