How to bleach clean a glass 35g?

How do I bleach treat an all glass 35g aquarium to kill bacteria and parasites?

Has your tank sat dried out any? What parasites and bacteria issues are you trying to target?

Imho, I would not bleach it. I suspect bleach is real hard on silicone. Give a good white vinegar cleaning, rinse big time, vinegar again, and really really rinse and let dry. Then you could (but is not necessary) do up a very heavy salt water mix, let sit a day or so, then rinse out. Also remember to vinegar soak all ornaments and filter parts that touch water. I would get new gravel instead of trying to clean it, although you can clean it by boiling.

Last year I had a very bad case of Black Beard Algae. Like you thought Bleach was the way to go. Probable did a 10% bleach wash on the tank and substrate (gravel). This was way to much and my room smelled like bleach for a week. I believe the white vinegar and boiling the gravel suggested above is a better option. If you believe bleach is needed, recommend a low concentration used. Black Beard Algae is spread by spores so the bleach really didn't help as I thought.

For reference, I was able to restore my tank and it is going well. Tried dirt with a sand cap (Walsted method), so far hair algea and a few stowaway snails have been my only complaints. Good luck getting our tank ready for new fish. This is what my tank looks like now, work in progress.

If the tank is still up & running, there probably isn't a real need to completely breakdown & sterilize the tank: unless there exists an unusual situation.

Parasites need a host and die off in short order without one. Bacteria usually only attack weakened fish.

Leave the tank vacant for a few weeks then carefully restock healthy fish.

Bleach is ok for items you can remove, soak, and rinse very well. For anything else, use H2O2 as it does the same thing as bleach but breaks down into harmless water and oxygen within 24 hours of being exposed to air and light.
