ADA Ammonia Spike Time Frame

G'day All. How long did it take for your amazonia to stop leaching ammonia? How often did you do water changes?

I'm on my 3rd or 4th week, and it still seems like it's leaching ammonia.

Thanks!

It probably is. From what I can gather, this process can vary greatly from bag to bag; some leech more (and longer) than others. 2-3x weekly 70% water changes are recommended, but increased frequency/amount is not out of the question and really the only way to combat the problem.

Looks like I'm going to have to up the amount of water changes...
I was looking forward to getting some shrimp soon too. Ah well.

Mine took almost exactly a month for ammonia and nitrite readings to disappear.
It happened very suddenly as well.

Some never really did, one has been on the 5-6th week now.
I added high current for O2 mixing and that seems to help likely via bacteria and all the waste they are processing.
Some 2 weeks and I was fine.

Hard to say.

You can do small jar test and add a little Excel to kill the bacteria without oxidizing the AS. Then another with some mulm water and then measure the NH4 over time.

By knowing the volume of sample jar water and the volume of the ADA AS, you can extrapolate a rate (NH4 ppm/unit time) and you may as well measure pH/KH/GH as well. Make sure to add O2 to the bottles and a little current of some sort to each.

I don't quite understand this- what bacteria does Excel kill? I understand what adding mulm is supposed to accomplish, but I'm missing something about Excel...?

I think after 4 or 5 weeks, the amazonia has begun to stop leeching, or at least not as much. I did a few water changes over the weekend and it seems to be leaking less. After the first water change, I waited a day before testing the ammonia, and it was .25 give or take. I did another water change, and the ammonia is at 0. I'm waiting for a few days and testing it again to see how much more has leaked. I thinking a few more water changes should do the trick.

And a few weeks later, the ADA is still leeching ammonia...slowly getting impatient. I want to start stocking the tank.

There's variation, I'm not sure there's really any solution really.
Water changes, wait, lots of plants etc.

yep, patience is the key. mine have gone as long as 5 weeks, and i did daily 80% water changes. cram it full of as many nutrient sponges as you can (foxtail, elodea, fast growing stems) and keep doing your water changes. you mentioned shrimp, and they are the one thing you dont want to take any chances with, they cannot take as much ammonia or nitrates as say fish or snails.

Thanks for the replies. I'm doing water changes almost every day if not then every other day. The fast growing stem plants I have in there are rotala green, some sort of hygro and wisteria (sp?). The rotala is growing nicely.
I'm about to do another water change tonight. I checked the ammonia levels a few hours after last night's water change, and it was .25 or .5 hard to tell the difference, but it has been at that level for weeks.

I suppose I'll keep on waiting. I don't want to spend money on shrimp and have them die off.

My expereince on two tanks has been to add some plants and dose Green Bacter. This drove the ammonia and nitrite two zero in less than two weeks. The nitrates took about a week longer to get in the 5-10ppm range (which is what I needed for my CRS).

Well, not on my batches, Bacter smacter............that would not have done a dang thing...........

I had a fully mature XP4 fully loaded and added fresh purigen and Zeolite as well to a 38 Gal tank, and I did a dry start method that should have cycled the sediment some prior for for 3 weeks. I added old tank water from mature aquariums.

I did 3x a week 80-90% water changes.
Nothing would stop it after 5 weeks later.............
No amount of plants, bacteria could stop this........

Only time and dilutions..........

Eventually the AS stopped leaching.........some folks have had it turn to mud muck very fast.......

Now I've had some where it did not matter a bit, I added to fully stocked tanks without issues............

So that tells me that it's pretty variable....just like soils can be......
Consistency of product is not always easy, however, the inert brands, like EC even have their issues, Flourite can be extra dusty etc.

Still, a replicate of 1 tank hardly tells you much, you can say the tank started off nice etc, but you cannot make generalizations or predictions.

I've done 16 tanks with it now. Maybe 30 pots at the lab.
I'm leary about doing the nutrient analysis on it as the batch to batch differences are so wide and I may not get a good random sample.

I really do not think we can say how long it takes for the NH4 to stop leaching out or not.........obviously there is some limit and it might be about 6 weeks or so........at least based on the tanks I've done and seen.

Still, that's a lot of work and PITA.
The 38 gal is fine now 6 weeks later.

So it did finally stop.
But no amount of prep stopped it.........
A couple of other local members had a similar issue.

Tom Barr

Thanks for the info Tom. Makes me feel better that it will stop one day. I'm also doing 90% water changes. I get all the water out until the water is the same level as the substrate.
But it looks like my hopes of stocking the tank with shrimp will be put on hold for awhile.
