Hello everyone i have a tiny almost unnoticeable leak in my sealing of my tank. The only reason i notice it is from the salt build-up along the sealing no drips and not water level dropping, but how could i fix this? Would applying Tank Sealant on the outside work?? or would i have to drain the whole damn thing? Thanks in advance.

Are you sure it is a leak? Sometimes we spill water when we stick our arms in the tank and the water runs down the glass. When the water evaporates, it leaves salt residue along the bottom of the glass along the trim.

Yes im 100% sure in not spillage or anything because i wiped it off and acouple of days later (without any activity with my arms in there or anything) the salt came back in the same pattern and same spot...right along the seal.

i got the same thing, its on the bottom back of my tank. its been there for a while, i just leave it there, cause im not takin my tank down even though i just started it. i may try and put some sealent on the outside, maybe it will work, or maybe it wont. if the water isnt like dripping onto ur floor, causing ur floor to rot or anything, it probly isnt a big deal, but maybe im wrong, maybe it is a big deal.

little leaks always turn into big leaks. ive never know different. maybe in three months, or maybe three years never can tell, but it will keep on getting bigger. because of the pressure behind it i think it would just pop any sealing job that you try. but get a small thing of sealant and try. see how long it takes to pop it off and then youll know how serious it is. IMO

1. Locate the exact source of the leak and mark it with a felt tip marker.
2. Reduce the water level in the tank until the leak stops.
3. Thoroughly dry and clean the area of and around the leak with a paper towel, or soft cloth.
4. With the razor blade, scrape the existing silicone from the leaking area, and an additional one inch area around the source of the leak.
5. Clean the scraped area with the acetone applied to a paper towel, being careful not to over staturate it or allow any acetone to run or drip down into the aquarium, and let dry for a few minutes.

6. Apply the silicone sealant to the cleaned area, working it into the glass joint area.
7. Allow the silicone to cure for at least 12 hours, 24 is better.
8. Refill the tank with water to the desired level.
9. Check to see if the repair worked and the leak has stopped.
Tips:
1. Not all sealants are suitable for aquarium use. Use only non-toxic 100% silicone sealants, such All-Glass® brand.
2. Pinpoint the exact location of the leak. Water will be at the bottom of the tank (gravity rules), but most likely the source of the leak will be somewhere else up higher or sideways along the joint or seam.
3. If patching the leak from the outside of the tank does not stop the leak, try patching it from the inside.
What You Need:
* 100% Silicone Sealant
* Acetone
* Single Edged Razor Blades
* Paper Towels
* Felt Tip Marker
* Tank Replacement Water

Thanks. Yeah i guess that is the most logical thing to do if it works from the outside give it a try if not gotta go from the inside...it is up high so it wont be difficult from the inside.
