    Hi I have a tank that im making a sump out of. 2300x700x720. What I would like to know is. I want to split the tank and clean the silicone off and redo it. Good idea or bad idea.

    Awesome dimensions.

    My answer (which is known to be ridiulous at times) is....depends on the glass thickness, if its 10mm or thicker, the glass is worth keeping for a long term investment if on a tight budget. By the sound of the dimensions, it's well over 10mm?

    Taking it apart and re-assembling gives you a chance to add bracing and customize......but 'time consuming' would be putting it nicely.

    How old is the tank? Has it been empty or full the entire duration of its life? If not has it stood in the sun? If so the silicone cane go brittle and necesetate a redo.

    Well the tank is leaking. Its just that ive heard that once you have had old silicone on glass and remove it the new silicone wont stick.

    Scrape off old silicon and use a solvent to clean off residue (I can hear the guys freaking) and then rinse thoroughly with vinegar water

    I stripped a sump 2 weeks ago with silicon stripper I bought from builders. works beautifully . Just make sure you clean the glass properly before reassembly. well worth the effort. You end up with what you want and piece of mind. good luck and enjoy.

    I have refurbished many an old tank and you need to make sure all old glue is removed the area cleaned with methylated spirits and then comence with glueing.
