Hi,

I have 2 molly's in a 10 gallon tank and added 3 danio glofish to the tank (I was told that was fine - correct or not - and that is what I did).

The tank was cycled before the molly's and stayed that way with these numbers:
ammonia 0.25 (really never ever goes lower)
Nitrite 0
Nitrate 20

Then come the glofish and currently I have
Ammonia 0.25 (was 0.5 - I added more safestart which seems to have lowered it)
Nitrite 8 (as high as the test will show)
Nitrate (did not get to check yet)

When I first cycled the tank when the ammonia was 0.25 the nitrite was immediately zero (such that I wasn't sure the reagent was even working).

So...I guess the glofish induced some cycle where the bacteria are converting ammonia to nitrites but there are not enough bacteria to process the extra nitrite load?? Does that sound right?

While I am waiting for this situation to fix itself, do I need to do daily water changes?

Anything else I can do to help the situation?

Thanks!

Yes, it sounds right, alright I don't think you were cycled to begin with. 5 glofish is a lot for a 10 gallon. As said in your other thread you are overstocked.

Yes, you need to be doing water changes daily.

Anything else I can do to help the situation?
I'm almost sure this isn't what you want to hear since this was the advice on your last thread about much the same thing (cycling issues), but you could return the fish. I'm not trying to jump on your case, but you are overstocked. You're allowed to make mistakes, everyone does. It's what you do about those mistakes that matters more.

Hi,

Thanks for the reply.

Just to clarify, if I need to return the fish, then what is the goal of the daily water changes? Or is there a chance that daily water changes will allow the tank to finish cycling while keeping the fish safe?

Thanks,

If you don't want to return the fish listen carefully since I'm about to give you a piece of advice I wish I had when I first started. First of all, you might not have sufficient bacteria in your tank to keep up with the bio-load therefor your tank is overstocked. You can try to increase the bacteria in your tank by having more area for them to multiply. The first thing I will tell you is to go to AngelsPlus.com and buy an "active sponge filter" that will come with bio established bacteria and will cycle your tank in no time. Plus by adding another sponge filter you will have more area for the BB colonies to grow.

While you wait for your wonderful life saving active filter, monitor your parameters every single day. And yes! You need to keep doing daily water changes to keep ammonia, nitrites and nitrates down, until you have more Beneficial Bacteria in your tank. Goldfish are messy fish, so 5 in a 10 gallon tank is going to be enough border line.

Good luck!

The point of the water changes is to keep the fish alive, until you see if you can return them. 4 ppm nitrites are lethal. You've obviously researched the ammonia cycle (kudos for that, btw) and know that already. You're just looking for the answer that you want to hear and I don't want to give it.

Daily water changes will not fix the stocking issues. The glofish need more space becuse they are active. The mollies need even more. I don't even know the sex of your mollies, but if you have a male and a female that in itself is bad. Both because liverbearers have lots of babies and because one male liverbearer will torment a single female. Livebearers should be kept two females to one male, something that can't be accomplished in a tank too small for even one.

Unfortunately, your tank seems to have perhaps never cycled, as any ammonia in the tank means that it hasn't finished. I'm not sure why that is, but bacteria can be a fickle thing. I agree with the advice blackwaterguy has given you.

As the the ammonia never lowering, have you checked your tap water for ammonia?
I'm sorry you've had so much trouble in this venture.

If you return the fish, we can suggest more suitable species (such as male guppies, a betta, etc.)

Could be...the tank had an ammonia level of 8 at the start....which then went down to 0.25 (my tap water is 0.25) after I added the starter bacteria, and zero nitrites and 20 nitrates....

hehe, this is actually going alot better than when we started with guppies (but we were even more ignorant then and the petstore people said we can just get started without cycling the tank) - 3 weeks for a fish is a record for us :)

Apologies. I was sincere about the kudos for the learning of the nitrogen cycle. You have more knowledge than the average starting aquarist and I half thought you were messing with us. ;)

Hi,

How exactly to I use the active sponge filter. Does it attach to my current filter?

Regardless, it looks like my tank has cycled itself again:
Ammonia: 0
Nitrites: 0
Nitrates: 20

2 Molly's and 3 glofish (not goldfish) - maybe I got lucky!

Regardless, they are doing ok, but if this sponge filter will help, I am interested.

Thanks,
Juggernaut

Live sponge is an elaborate way of transferring nitrifying bacteria into your tank to cycle it. If you're satisfied your tank is cycled, you don't need it.

However, your tank sounds maxed out. Using a regular sponge filter gives your bacteria more area to grow into a bigger colony.
