hi i recently bought a 64l fish tank let it cycle for 3 days then added 3 platys which are hardy fish to cycle it that way i test the nitrite yesterday it was extremely high at 1.6 so i did a 75% water change yesterday and last night tested it it showed the level to be 0.3 which was a lot lower but i tested it again this morning and its gone up to 0.8 why does the nitrite keep rising should i do another water change
??
and also should i remove the 3 platys back to my established aquariums for now ?

keep.doing the water changes, you'll get there eventually!
But if it helps to bring you back down, i myself refer to the beginners section for information from time to time.
