I will have to let you know a bit later grandad, today is my day off and i decided to make it my fish day.
I have emptied the 30 gal and am slowly raising the salt levels and have read that i will need to raise it by 2 sg per week.
i am also battling to keep the 80 gallon clean due to it being in direct sunlight all day. thanks for the tip and i will get round to the filter once i have finished the salt tank.
