It depends on the condition of the silicone.
Aloha Craig,
Buying used is an economical way to go, but if you have never done this before, starting out on a 150 gal is a big jump. I've bought and repaired used tanks many times over the years and I'm here, willing to help.
Repair is not as difficult as one may think. It does not require a complete tear down or even complete removal of all silicone. The removal and re-silicone of the inside seam of the affected area is all it takes, but it's a good idea to go a little further and remove the silicone along the entire affected inside edge, one inch from one inside front bottom corner to an inch shy of the other inside front bottom corner. (That is, if the corners are intact.)
Typically the structural seams and corners are intact on leaking tanks, but the silicone in a small area has released. (Sometimes it releases when a person pulls up on the plastic frame instead of lifting from underneath the the tank.) In essence, plugging the area where that hole has developed does the job.
Since this is the first time, if you would like to make sure it's done right, that there is no structural problem, and if you can take the time, please show us a good quality picture of the entire tank front and another of the entire bottom. Also show us close up pics of the worst looking silicone wherever that may be, and another pic at the point of the leak if you have pinpointed where it is by seeing where the water is seeping through. Speaking of that, does it leak only when mostly filled or when there is just an inch of water?
If you would like to send the good quality pics to me I can re-size and post the important ones here. My email is
[email protected]On the other hand, if you call me we may be able walk through this without pics. I know what to look for and can help you decide where to re-seal.
Mahalo,
