well its all in, ha ha
sort of, the syphon seems to have an air leak, so although it works i dont full trust it, im taking it to work tomorrow and sealing it propperly, just to be safe.
the sump itself works well, i had to make the holes bigger in the drip plate, im keeping my eyes open for a tray of some sort.
i also added more filter media, with more to go in as i have more room, other than that im pretty chuffed lol
