Question I think my tank has cycled..questions?


I think that my 5 gallon tank has cycled. I've had it running for about a month now. When I first started a month ago I added 5 glofish right away. They all got ICH and died. Well....I now know that 5 fish is way too much for a 5 gallon tank. I'm pretty sure they all got the ICH because the tank wasn't cycled. I have no fish in my tank right now. I want to make sure the ICH is gone and the tank is cycled before I add any fish.

I just tested the water...

ph 7.6

Ammonia 0

Nitrite 0

Nitrate 0

I have several questions....

What is the Ph supposed to be? How do I bring it down?

Should I do a water change before I add fish?

Should I change the filter before I add fish?

What type of fish is suitable for a 5 gallon tank?

Thanks...
Debbie

Sorry, but you would only be cycled if you were adding a source of ammonia in the form of say fish food or pure ammonia. The bacteria needs a food source. You don't have any nitrates which is why i think you weren't adding any source of ammonia. If I'm right, we'll help you figure out how to cycle. If I'm wrong then we can move on to the rest of your questions.

fish food

I was using fish food to cycle the tank....the water readings were high on everything about 3 or 4 days ago.

I'm guessing you haven't done water changes since you asked about that. Do you have live plants?

No I haven't done any water changes. I have one live plant.

What kind of plant?

What were the parameters at a few days ago when they were high?

I can't remember the name of the plant right now. sorry

I did a water test about 3 days ago. The results...

Hey Debbie, looks like you've gotten some good input here. . . I just stumbled onto this thread and thought I'd see how things are progressing for you?

My guess is that your tank isn't fully cycled yet based on the numbers that you've posted here.
It looks like it was close before that last water change, though. . .

Your pH should be fine.
DO NOT change your filter - there will be beneficial bacteria on there that you don't want to get rid of!
I'd hold off on adding fish just yet, if possible. . . just to be safe and sure than sorry!

My question is WHY have your numbers fallen from 20ppm of nitrate to zero so quickly. . .

To help us figure this out, some additional questions for you:
How much water did you change, and did you use a dechlorinator?
Have you been adding fish food since your last post, and what are the numbers now?
Can you tell us if your plant is a stem plant, as opposed to a rooted plant or a rhizome plant? (or take a picture!)

It is possible to have a cycled tank that shows no nitrates after the initial spike - it doesn't happen very often, but the possibility is out there.

I'd personally add a largish dose of fish food, and track the numbers daily or even twice a day to see what happens with them. If you see them fall quickly back to zero, than your tank is cycled. If not, you may have more work to do before you're ready to add stock.

... hope this helps?

I haven't done any water changes since all of the fish died. That was close to 3 weeks now. I've been testing the water every few days. Yes, there was a huge spike in nitrites, ammonia and nitrates for a week or two and then it all went down to zero. I do have one plant. I can't think of the name of it right now. I'm going to take some water to the LFS and have them check it out this week. I do have the API water test kit. That's what I use.
Should I be doing water changes?
I will put some more fish food in the tank and see what happens. There is still a lot of food and waste in the tank from the previous fish.
There are no fish in the tank right now.
Also my pH is way higher in the tank than it is in the tap water. Tap Water is 7.4 and the water in the tank is 8.2. Go figure!
