New 75 gallon

I am new to the club and wanted to see if i can get some help setting up my 75 gallon.
my name is chris and i have 2 or 3 month old 75 gallon that i think is fully cycled now…
i’ll post some pic’s later but right now i just introducing myself. To cycle my tank i used water from my 2 year olds fowlr 29 gallon . i put about 20 gallons of new water and then i added water from the 29 every other day when i made water changes. i went through the diatom cycle pretty fast and green algea. i have a sump /fuge thing going on and have some live rock with macro. My protein skimmer sucks …its an old one but it ddoes skim .
i have a seaclone that came with sump but its missing some tube pieces and the pump. bought a pump but didnt know how to arrange the pluming.

The seaclones run on a MaxiJet 1200 power head. if you use it in the sump you dont need all the curved tubing. just shove the nozzle into the hole in the bottom of the seaclone. it does need the air injection nozzle. if you have that. it looks like a little basket, with a air tube fitting in the center. it goes in the suction side of the pump. the air hose with valve goes on the center basket fitting.

thanks i bought a maxijet for it but for the valve it kept shooting water from it instead of sucking air…
