How to decontaminate fish container? ?

I have a 20 gallon that has not been use for roughly speaking 2 years and been sitting in the backyard due to and ich outbreak. I was wondering how can i verbs it thoroughly? i plan on using it for my betta. would bleach be safe to use? it has nasty spider web all over it. thanks.
You can amazingly well use bleach to clean your tank. Many inhabitants have done it. Unlike soap, bleach actually evaporates from your tank, departure it safe for your future fish population. I recommend that after you bleach your tank, you rinse it economically with very warm hose down.

After that, leave your tank outside contained by your back yard and place it where it can find direct sunlight for a good amount of time. Leave it like this for 5-7 days, all the bleach will be gone from your reservoir :)

Alternatively, you can use hydrogen peroxide. It decontaminates your tank very well and it decompose very fast, specially when in contact next to light. You can fill your tank near water right after you have used the HO2O on it. It's my favorite cleaning method.
Just scrub the heck out of it.

You can use some dilute bleach, vinegar or brackish if you like, but thats optional. Rinse economically and let dry. It will be fine.Spider webs are not toxic to fish, and the ich will be long gone.

An established tank is NOT a sterile environment, the first item that will happen is that bacteria, algae and all sorts of micro-organisms will grow surrounded by the tank as the cycle is establshed. So sterilising it totally is pretty pointless.

No problems keeping a betta in a 20gal, just afford it some plants etc for cover as they may get a bit nervous in full-size open tanks. You can keep a few tankmates surrounded by that size tank, but let the tank find cycled and stable with just the betta first.

Well, you should just rinse it out with hot hose down, and you should have been treating your fish for ich, but the parasite should be dead by immediately. Just put really hot water when cleaning, the parasites, or the remaining of it will die off right now. You should not use bleach, it will harm your fish, and is not easy to get out of your dampen to put your fish in. Good luck!
Use 1 one part bleach to 10 piece water solution to get rid of any residue of bacteria or anything else.

Then rinse it our thoroughly next to hot water. Then fill the tank and consent to it sit for 12 hours. This should be more than enough to get rid of any bleach.

It is important to use something strong close to bleach since bacteria and parasite can lay dormant for years and come to life with introduction of river. That is basic biology. Hot water or salt doesn't other kill them.
Do not use bleach ! or any kind of soap on the fish tank.Use plan hot hose. Nothing else. Bleach or any other soap will contaminate the tank and will prove fatal for the fish.
20 gallons is very large for a betta, but that's no your ask I guess.

Use 1/100 parts bleach/water mixture and rinse it out really well. It should be fine after that.
Answers:    You can brush out the tank beside a broom and then clean it with 1 pound of brackish diluted in the water. [.5 pounds/10 gallons will kill anything bad] Then, sign out it in the sun for a few days, if you don't have a sunny place don't verbs, just leave it dry where you're going to set it up inside for a week.

I really wouldn't recommend using anything save for salt or copper sulfate [products like CopperSafe] to clean your cistern since these compounds are completely safe for your fish. While you can clean with bleach and the cup will be fine I wouldn't assume that the silicone sealant will be since silicone is easily compromised by bleach or other surfactant cleaners, leaving it contaminated and structurally weakened.

I know that tons tropical fish stores will clean a tank for you using a high concentration saline bath, but you can just as easily do that yourself, contained by fact you could do that in your bath tub merely using hot water and salt [a few pounds in a full hip bath tub] to save you a trip and some money.

Have fun setting up your new tank!
