Exclamation My tank is cycling again !!! Help. What should I do?

I have 1 siamese and 1 molly in 20 litre tank. I had already cycled my tank before adding them. Since I had added them into tank all the water level had spike again I have done water change but still I have no luck I also have added ammonia lock which has lowered the ph level but has dramatically spiked.

I have had 1 fish pass away already and I have had them for 4 day now...

What should I do? Keep doing water change? Should I do vacuum clean?There is all lot of green algae growing in my tank. I know my tank is small for my molly but I have been looking at purchasing bigger tank. I have 1 nitrate snails in my tank at the moment.

Ammonia 4 -8ppm
Ph 7.6 darker
Nitrite 0.25ppm
Nitrate 10ppm

I think my betta has got ammonia burn what should I do? I'm scared that I am going to lose them. Could it be my filter.

Oh your poor fish

How long did you cycle your tank prior and what method did you use? ie. Fish-Less with Shrimp/fish food/ammonia, fish-in or did you use any cycling products?

With ammonia burns you can use a bath of Methylene Blue to help, you would do it in another small container like a 3.4 liter (1 gallon) or anything smaller will be fine as long as it's not smaller than 1 liter ideally; just makes dosing easier if you use around 1 gallons. It's good for treating both ammonia and nitrite burns.

What kind of filter do you have in the tank? I think that's enough questions for now, it's okay if you can't answer some just do your best ^_^

Yeah, keep doing daily water changes if you can, if not every other day.

Can you test your tap water for pH, ammonia, nitrite, and nitrate?

Did you add the fish all at the same time? Or gradually over a few weeks?

Sorry MissBec, but based on your post Ammonia won't go down? Need advice? it doesn't seem like you were done fishless cycling. You were getting there but not done yet. Fishless cycling is done when your aquarium can convert 4 ppm of ammonia to nitrates in 24 hours.

First thing, absolutely no more fish. 20 liters is about 5 gallons. That's enough for a Betta and a snail, but not anything else. I know you said you're planning a bigger tank, but we have to deal with things right now first. That's just too much bioload.

lilnaugrim gave good advice with keeping up the water changes. Make sure that when you do you are using a dechlorinator that will lock the ammonia. This will be safer for the fish, but will give you a false high reading. That's ok. Fishless cycling takes work, but it's not the end of the world and people on here can help you through it.

One other thing, not sure if you have plants, but they will help. Floating plants especially since they will grow quickly even with stock lighting since they are so close to it.

I thought I did completed the fish cycled... no one responded to my post so I talked to this guy at the pet shop he said it did cycled, I have been talking to guy for about month and half. I was alway in and out of the shop now I know not to trust him!!!!

How long will it take my tank to cycled while I have fish? What if I added another filter in my tank? Or would that be overload ?

I added all this fish at the same time

Adding a second filter will give bacteria more places to grow, but will not increase bacteria. I'm going to be honest and say I've never had a tank that small. I almost wonder if a second filter would create too much current for you. I'd personally pass, especially since you should get the molly into a bigger tank at the first opportunity you get. They get much too big to be in something so small. Since the goal is hopefully to move it you shouldn't be worried about additional bioload.

I can't say how long it will take. You have a start, so hopefully not too long. I would also stop feeding the fish for a while so you can get the ammonia back under control. BTW I said you should use a dechlorinator that locks ammonia, that is unnecessary since that is what your Ammonia-Lock is doing. Your test is reading high because of it, otherwise at those levels your fish would be dead already. Keep using that and keep doing water changes.

What type of floating plant i should get? Also Can plant cause ammonia?

I feed the fish twice a day should I cut back? Betta seems to have big apetite she alway eats the Molly food. How many day should I stop feeding them or should I cut back to feedibg to once a day?

I recommend Water Wisteria or Anacharis for good ammonia soaking plants. Basically the faster the plant grows, the more it soaks up excess ammonia and other nutrients; this also helps keep algae away too if you have enough plants.

Were you bringing samples to the store to get tested or just talking to the guy? He might know his stuff but just didn't know your situation is all. Each tank is different in some ways depending on if you've got live plants or not or how your water is straight from tap. Generally it does take a month so he was most likely guessing that it was cycled, I wouldn't hold it against him really but politely inform him is all. You know when your tank is cycled when both ammonia and nitrite are reading zero, nitrates will be high but you'll do a large water change to decrease them and them test the next day and both ammonia/nitrite again should be zero and nitrates will be mostly acceptable range. If ammonia/nitrite are NOT zero then the tank is not finished cycling yet. Generally we recommend testing for a whole week just to be completely certain that the tank is cycled and ready for fish.

You can fast the fish for around a week right now just to really get that ammonia under control, it won't hurt them at all. And then you can do once daily feedings afterwards and then go back to your twice daily if you so wish to. What foods are you feeding them? Higher quality food won't foul the water as much, is why I ask. If you do want to feed them make sure there are absolutely no leftovers!

For floating plants I'm personally a fan of Amazon frogbit, dwarf water lettuce, and wisteria. Red root floater is also nice. I've never had success with watersprite. Rotala rotundifolia was a nice easy to keep stem that may or may not work since I don't know your lighting situation. I'm not sure what plants are available in Australia, but any floater should work for you. I consider duckweed a nuisance, but have to admit it grows quickly. You'll just never get rid of it ;)

lilnaugrim is right again. If you told the guy at the fish store that you had zero ammonia and nitrites and were showing nitrates he would assume you had cycled. Which is right. I just prefer to see more bacteria built up from the start to avoid situations like this. I'm also leery of using food or shrimp to try and fishless cycle. My preference is pure ammonia since it is much easier to know how much ammonia you are adding. I didn't relize when I was trying to help you before that you were using food. That was likely why your ammonia was so high. My fault for not finding out and I'm sorry.

Not going to repeat the rest of what lilnaugrim said. I personally only ever feed once a day and also fast once a week.
