Parameter Readings
 
With hat in hand, I confess that it has been a long, long time since I tested water parameter. It's a ten gallon tank that is probably 30% overstocked by inch of fish per gallon standards and I have a sneaking suspicion that I tend to overfeed a tad. The tank has been set up for around 7 months and never went through a proper cycle. I have a moderate amount of live plants in the tank. Here are my readings taken about ten minutes ago.

Ammonia: .25 Nitrite: 0 Nitrate: 40

Does this sound about right for the situation I described, or am I color blind ?

Ammonia should never be above zero. And nitrates at 40ppm is on the high side. We try to keep them below 20ppm, but as low as possible is always better for fish.

What fish are in the tank?
How often is a water change done, and how much of the tank is changed?
Are any substances other than water conditioner going in the tank?
Do you have live plants?

And, have you tested your tap water on its own for ammonia and nitrate? It would help to know if the high levels in the tank are due to the tank, or partly from the source water, as this can make a big difference in action needed.

6 neons- 1" including fins
3 cherry barbs- 1" including fins
3 cory catfish- 1 1/2" including fins
1 ADF- 1 3/4" stretched out
1 ADF- 1 1/4" stretched out
Fertilize with Seachem Flourish at each water change.
Change 30-40% of water once a week. Last changed yesterday.
Moderately planted with 1/2 stem and 1/2 slender leaved plants.
Tap Ammonia .25
Tap Nitrate 0

My poor old eyes could be off on the ammonia but, the nitrate is pretty obvious.

OK, this is better, but there is still an issue. But at least the ammonia is in the source water, or as you say it may be zero. I wouldn't worry about this, especially with live plants.

The nitrate is high though, and that is simply the bio load. The fish are not bad (though more than a 10g should hold looking forward to maturity) but I suspect the two frogs are adding a lot of waste. I've no direct experience with these species, but I have read they add a lot. I would increase the volume at water changes to 50% of the tank, and make sure you vacuum the substrate at each change. This will help with the present stocking, but plans for changes would be in the best interests of the fish and frogs.
