Yes, that's dolomite. See if you can get it in a finer grade, i.e. gravel rather than chippings. It will be easier to put in the filter, and the smaller the particles the easier they dissolve. They dissolve very, very slowly. But this is dolomite. Probably 2-3 tablespoons will do it. Livebearers won't mind hard water, so no risk of getting it too hard...well, within reason anyway. The hardness (and corresponding pH) will rise over a few days after this is placed in the water. It is best in the filter, where the tank water flows through it regularly. I like the little mesh filter media bags you can buy in fish stores, but it could be just placed in a basket in a canister filter or mixed with other media, so long as it doesn't go through the openings into the filter motor and impeller.

Ammonia is coming from somewhere, is this a new tank?

What water conditioner are you using?

StressZyme is not strictly speaking a tap water conditioner. I checked API's site, it does not mention that this products detoxifies chlorine/chloramine, which is what a water conditioner should primarily do. I am not a fan of StressZyme because the "breaking down" of organics creates ammonia, so it will increase. Also, natural bacteria in the substrate should handle this, and benefit the plants.

Will try get the finer stuff and put some in my filter, which is a fluval 105 canister one so should be easy enough to put in there.

The tank has been running since the last week in May but has only had fish in it for the last 2 weeks or so. I use Nutrafin Aqua+ as a tap water conditioner. I'm using the Stress Zyme primarily because i was hoping it would help with the biological part of the filtration as the filter is brand new all new media and everything in an already established tank so I'm wondering if it may just be as simple as the tank adjusting to the new filter so to speak whilst the bacteria take up home in the filter?? Also i had the filter running at slightly less than half of what i could run at as my heater seems to struggle to heat the tank properly as it creates a pretty strong current in the tank but this fish seem to have great fun with it so I've turned it up and left it. If the temp starts to drop to low i'll turn it down again. I don't really know what would be the best water conditioner to use as there are so many i just dunno what ones are good and what ones you might as well be adding tap water...

I tested my water not to long ago and the ammonia seems to have gone down a bit after doing the water change. Its closer to the color for 2.0 than 4.0 now.

I'm gonna cut down on how much i feed them and see if that helps any as well, although i didn't think i was over feeding them but maybe i was.

Thanks

That dolomite is perfect.

Adding the fish started the cycle, so that explains the ammonia and nitrite. I still recomend discontinuing the StressZyme; breaking down organics faster, thus creating more ammonia/nitrite, is not what we want in a new tank. Change water daily, half the tank, until ammonia is below .25 and nitrite the same. Using a conditioner that detoxifies these (along with other stuff) is advisable until cycling is complete. Prime by Seachem and Ultimate (forgotten who makes that0 are two I know of. Nutrafin AquaPlus will not handle ammonia or nitrite.

Tossing in some live plants, even floating stem plants, will help with the ammonia/nitrite too.

If you haven't already, teswt your tap water on its own for both ammonia and nitrite. Good to know if either is present.

Okie dokie dolomite, media bags and prime all ordered so should be here in a few days or so. Any other stuff that would be handy to have at hand? incase of emergency's cause i can't drive hence why I'm always ordering stuff instead of going out and buying it there and then :o)

I have 2 quite large live plants attached to some driftwood already in the tank so got that covered and i have a little one in my fry tank as well. I want to get some java moss or something similar as a floating plant for the fry tank and my main tank but i cant find it anywhere over here O.o

I tested my tap water earlier as well and there didn't seem to be any of either in the tap water so thats a bonus! lol

Thanks for all your help!! Me and my fishies appreciate it

Sounds good. Look around for some Brazilian Pennywort, it is a stem plant but one that does very well left floating, and for fry it is ideal. Cabomba also works, but Pennywort is less "fussy".
