Now that your tank is producing consistent nitrate, I wonder if your low (0.25ppm) ammonia reading might be a testing error. I've noticed that some API test kits are off a little when testing small quantities of ammonia.

Somewhere on the Seachem page they refer to Prime leaving a residual ammonia reading even when the ammonia is actually 0.0ppm.

Id' rather not re-read this thread, but ...have you calibrated your test kit by testing some distilled or RO water? Distilled water with Prime?

Prime is effective against 0.25ppm ammonia at a dose of 2-drops/gal. You might consider cutting back.

Prime will still test positive for ammonia even though all the ammonia is locked up.

I would try not doing water changes and just replacing the evaporative water with untreated tap water.

I think you will find that in a week ammonia will test 0.

The api test kit does have a false low reading in saltewater tank which I think is due to the colors. I constantly read it at .25 when fish and corals had lived and thrived for years.

But in FW I get a nice clear reading that was obviously much below .25ppm.

my .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

True. Prime reads TAN (Total Ammonia Nitrogen), which is ammonia plus ammonium. It's something we have to explain regularly to newbies.

What I meant is that API test kits can vary. My first kit read very clear yellow at 0.0ppm. My second ammonia (only) test read 0.25ppm green even when there was no TAN --- as calibrated with distilled water. My next full test kit read about the same (looked like 0.20ppm green). My current kit reads half-way between. About the equivalent of 0.12ppm.

There is no ammonia in my tanks.

I mean no offense .. But bob, why are you here when you don't even believe in cycling a tank ? I am lost at what you can offer the OP with your ideas...
Uuuhhh.. So yeah, my tanks also always show no ammonia .

Carlos , I might try another ammonia test. I had one kit that always was unclear between .25 ammonia and 0.

No I haven't calibrated my test kit, I can get distilled water on my way back to the house tomorrow and check on that. For now I'll cut back on prime today I'll add as you say 2 drops per gallon ad test tomorrow

Agent13 what other test kit for ammonia I can get a local petco or petsmart ? or even amazon Maybe I can take a look on that too


Just want to thank you all for stay here :) btw readings still the same

Ammonia 0.25ppm
Nitrite 0.25ppm
Nitrate 5.0ppm
Ph 7.0

It can't rain all the time

I've used sera aqua test kits in my past .. Don't know for sure where they are sold now but they were very accurate.
Even a new API ammonia test can't hurt . Either wAy I feel you are close if not done with the cycle .

A real world test is if nitrate continues to increase with no increase in ammonia or nitrite. If nitrate is building up, but ammo+ nitrite remain stable, then that would indicate a stable tank....not perfect but stable. THEN we can think about test accuracy and color of test solution. If nirtite accumulates at all then were still not cycled.

As I understand this tank for the last 2 months you have been doing water changes with Prime, plants and fish are doing fine, and you still are measuring ammonia among other things.

You might try the seachem multitest ammonia kit and measure total as well as free ammonia. Or even one of the seachem ammonia in tank dots. The dots measure the free ammonia.

I think you will find the ammonia is all locked up.

Which to me means it is a artifact of using Prime.

As an example if you replace 5% of the water lost from evaporation with untreated tap water that has say 1ppm ammonia, the tank will only measure .2ppm ammonia. And even that will be consumed by the plants in a matter of minutes/hours.

Contrary to other posts here I actually do cycle my tanks. Just in a way that does not produce the parameter spikes.

I think you will find that by not doing water changes, and not using Prime your ammonia will drop to unmeasureable levels in a day or two. With nitrItes unmeasureable a few days later. Finally nitrates will drop down but that could take a few weeks.

Being as your fish and plants are fine you could also just keep doing what you're doing. With that I would expect that ammonia will be measureable indefinately.

Still just my .02

Very interesting! I would love to like this post and agree with everything bob said, but i think hes only 95% right. Only thing i cant go along with is using untreated tap water. I don' know exactly what Carlos' tap water like, but mine... i can smell the chlorine rising from it as it sits in 5 Gallon buckets waiting to go into the tank. It MUST be dechlorinated before use. Bob may be blessed with great tap water that is suitable for use in aquaria untreated, but i would always recommend to use Prime.
Other than that, bob makes a very good case. I would do nothing for a few days to see if your tank is stable. But keep testing in case its not. Also i would continue with a regular water change schedule for long-term tank mainenance, but that's only my opinion and others may know better than me.
Best of Luck!
