will i be ok?

so last night i was doing a full water change in my bubbleponics system, got the 1st 2 done then when i went to grab the new bottle of newts it was empty,(i know i should have checked) so its 8 o'clock at night my res is empty and no newts(base). so this is what i did. the cooler that i drained it to was not that clean, it sits outside its not meant to be clean, i took a strainer put a paper towel and filter it back in the jug. i did 4 gallons like that then 2 gallons fresh water. i will be doing a full water change 2night on that system. was this the best way? incase someone else dose this and will know what to do?:wall:
