hi bro .. i was demoralised by my tank which leak drip by drip near the durso piping area that runs down to the return pump too ... i when asking ard . and i was told to remove the old silicon and seal it with epoxy glue .. i was totally devastated... i tried just removing the silicon ard the area where the piping was connected and seal with silicon (can imagine the hassle and damage to stop running my tank for a few days ...)
but luckily it works i dont have to redo the whole thing..
i totally understand how you feel bro... dont give up, get it fixed and move on ...
Peace ...
