Help with cycle

I bought a 10 gallon tank about 4 months ago. I did this without knowing about the nitrogen cycle and stocked with about 8 fish. After a little research and finding this site I realized I had made a mistake. So now 7 fish have died and the last remaining fish which is a dwarf gourami seems to be doing ok. Before the other fish died we had what I believe was ick or fin rot or both. This was cured with tetra lifeguard. So now the gourami is using all his fins and is doing good. About the water...Through out all of this the ammonia has been between 2.0 and 4.0 ppm. Nitrites have been at 0 ppm and Nitrates have been between 20 and 40 ppm. I have used 2 bottles of tetra safestart which is supposed to be enough for 4 10 gallon tanks and nothing. I'v done water changes of different amounts from 2 to 4 gallons of water based on info from pet shop. I'v been using ammo lock between safestart applications. As per instructions didn't use ammo lock for 2 days before adding safestart, then not using again for about 5 days to give the bio a chance to work. I have cut back of feeding to a very small amount 1 time a day and alternate with flakes and brine shrimp. I use a gravel vacuum when changing water. We made the mistake of having to much gravel at first but now only have about 5 pounds. Started with 15 which I think was playing a role in high nitrates. Since cutting back on food and only 1 fish I though the nitrates would go down and allow the nitrites to kick in but has not happened. The water is so clear you can't even tell theres water in it. I have a Aqua tech hang on back filtration with 2 filters. I have changed the foam one once and never changed the fiber one. Just rinsed in tank water when changed water. The filtration is rated for 100 gph. I have 5 fake plants and 1 castle for fish to swim in. I never wash them to preserve the bio on them. I just put a bottle of safestart in the tank about 7 days ago and numbers today were close to 4.0 ppm. 0 nitrites and close to 40 ppm nitrates. Added the ammo lock again today because of high ammonia. Using API master test kit for testing. HELP. How can I get the nitrites to kick in. Thanks for any and all help.

 

You can not allow the ammonia reading to get between 2-4. You have to do those water changes, make sure you always use dechlorinator, but you can't allow that ammonia to get over .25. If you have to change the water daily, then do so. Four months is a long time to cycle any tank. Are you cleaning out your filter? If so, stop. Your cycle is in the filter.

If those filter cartridges get dirty, just swish them around in tank water you are going to throw out. Never put them under tap water because tap water contains chlorine that kills the bacteria.

 

Welcome to Fishlore! I would suggest you stop the use of all chemicals (other than your water conditioner) and start up with large daily water changes, seeing as the chemicals don't seem to be working for you.

Also, if you could add some paragraphs to that post, that would really help a lot! Its a bit hard to read :;th

 

Thanks for the feedback. I haven't changed the fiber filter but did change the foam one with the charcoal when I treated for the ick and fin rot. Couldn't have the charcoal with the meds. What size water changes do you think I should do daily. 2 gallons a day or more? Also should I continue to use the ammo lock untill the water changes bring down the ammonia? Thanks

 

Thanks for the reply. What size water changes should I do per day and should I continue to use the ammo lock until I get the ammonia down? Thanks again.

 

Try 25% and test after you fill the tank back up and it's settled for a bit (unless you use something like Prine as your water conditioner, that reduces ammonia, etc, then wait 24 hours to test), and see how close to 0 ammonia that gets you. If that doesn't work, up it some.

If you don't have it already, get some Prime. It detoxifies all the nasties, but doesn't remove them. It's like the SafeStart, but lasts 24 hours, and allows you to do water changes as needed.

I personally would stop using the ammo-lock. But, I don't know anything about it, so I'll leave that to someone who knows about.

 

Ammolock works in the same way that Prime does.

 

Then it probably wouldn't hurt anything.

 

Thanks to everyone. Will follow advise and see what happens....

 

I have no idea if it detoxifies nitrite either, although a relatively small dose of NaCl does a great job all through the nitrite phase, costs next to nothing, and doesn't wear off like Prime does.

 

Who makes Prime. I don't recall seeing it at the pet stores in my area. We have PetSmart, Petco, and PetSupermarket.

 

Never mind last post. Found it. SeaChem. Will go tomorrow and get some. Thanks

 

Hi again, Just want to ask a couple more questions. I have been doing 2 1/2 to 3 gallon water changes daily since posting this thread and I have been using the prime as suggested. First question is since I'm only doing 3 gallon water change, what amount of prime should I be adding daily. Enough for 3 gallons I am changing daily or enough for 10 gallons which is the size of the tank.
Also I have been doing the water changes since 11/8/12 and the ammonia is still high at around 2 ppm. Still no nitrites. The nitrates have decreased to around 10 to 20. After 8 days of daily water changes should the ammonia be lower?
Thanks to all.

 

I think you are misunderstanding the order of the cycle and what you want to see. Ammonia is used by one type of bacteria and their waste product is nitrites. Then the nitrites are used by another type of bacteria and their waste product is nitrates. Ammonia and nitrites are toxic to fish in small quantities, and should be 0ppm all the time. Nitrates, the end product, are only toxic in high quantities (under 40ppm is generally safe, but you should aim for under 20ppm). You can cycle a tank and never see nitrites, especially if you're using Safestart, since it provides both types of bacteria to get you from ammonia to the end product nitrates in the bottle.

When I was cycling my 10 gallon, I did 50% water changes every single day for a month.. don't be afraid to change too much, the fish wants clean water. If ammonia really is 2ppm, I would do a 50% water change, let it rest a bit (to make sure the temperature doesn't fluctuate a lot), then do another 50%. I'd keep doing them till I had under 0.25-0.50 ppm ammonia. I generally dose the Prime for the entire volume of the tank (1mL for you) and pour the new water in after. Prime is safe to overdose a bit in the case of high ammonia/nitrites, so it won't hurt for these heavy water changes.

The fact you have nitrates and keep getting nitrates leads me to believe you have at some point gotten both types of bacteria, and have a cycle going.. you just don't have *enough* of the 1st type of bacteria to handle your ammonia load. You said you're feeding lightly, and you're rinsing the filter in tank water, and you're vacuuming the gravel each water change... is it possible there is a dead fish or something somewhere hidden in there that's creating all that ammonia? I cannot imagine a single gourami in a 10 gallon tank is causing that, they're not THAT messy of a fish far as I've read.

edit - also, since it's been 4 months, maybe it's time to buy a second ammonia test kit. Maybe yours is corrupted and you really are cycled with 0 ammonia/nitrites.

 

Thanks Terra for your reply. I will check inside the castle in the tank for a dead fish. I'm pretty sure we took them out as they died but I'll check to be sure. I just did a 3 gallon water change after checking my ammonia levels which were still above 2 ppm. I will wait untill later in the day and do a 50% change and will continue with 50% for a while and see what happens. Thanks again.
