With the recent leak to my 75 gallon, I will be sharing the process of resealing the tank and getting it back up and functioning.
There have been multiple threads concerning what type of caulking should be used, the process of resealing, and what steps to take to best prevent another leak- hopefully this thread can help others in similar situations.
I would like those who are knowledgeable and have experience to chip in- and those with concerns, to clearly ask so the forum can be best utilized.
With that said, my goal for the next few days is to simply remove the old silicone and apply a new seal. I do not want to rush into this and will be taking my sweet * time.
I will be using GE silicone 1 in the process. I know Dap and Dow have also been suggested, but at the time and my location- GE was the easiest to acquire. There was another member here building a tank who did a test and concluded that GE was one of, if not the best medium for caulking a tank- with a budget in mind- I will be looking for that link and will post it asap.
After getting the tank clean of most of the dirt and grime, I am using small razors- the basic flat, rectangular ones, to remove the old silicone. Rubbing alcohol and a glass cleaner that claims to be non-toxic will be used to remove/clean all leftover silicone.
With that said, I am mindful of not cutting into the existing silicone that binds the tank together. Now depending on the extent of the leak, I would determine if the whole tank needs to be taken apart. In this case, I feel that by replacing the small amount of faulty silicone used in the interior with a thicker seam of silicone- I will be able to successfully do the job(hopefully). I would suggest for anyone with a drastic seal problem to take apart the whole tank or fill in the problem areas with silicone using a small syringe .
(I know there are people out there skeptical of not removing all of the silicone and taking the whole entire thing apart- and redoing it all over)
I will update shortly on the progress and welcome anyone to chime in if I'm doing something wrong.
BTW, this tank will be dedicated as a future geophagus community. And for those interested in substrate, I will be using pool filter sand.
