Axolotls + MGOPM?


I'm about to transfer a 20g year old, low light, low tech tank to a med light 29g. Changing from black sand to MGOPM.

First concern is if the MGOPM could in anyway hurt the axolotls (amphibians), as they absorb molecules through there skin as well as gills.

Secondly, does changing over with the mix give off an initial ammonia spike? I have several Anubias, 2 Val's, 4x4 DHC, DHG, and a bunch of frogbit and DWL. Big canister filter with tons of foam ans seachem media = lots of bacteria. Thoughts?

I'm not absolutely sure, but I think people usually cap off the miracle grow. I believe it has lots of debris such as sticks and such and leaches tanins into the water. Sort of like peat moss?
I think it would be safe as long as it's capped and the substrate isn't stirred up.

Hi Luke, Didn't know the critter related question is why I didn't respond earlier. Scaleless Kuhli and Clowns yes but not never axolotls.

Regarding bagged dirt and the setup you are talking about that I can mumble about a little.

Miracle Gro Organic Choice Potting Mix is the bagged 'dirt' product I use.
MGOCPM (potting mix) contains soils and a large portion of organic material (55-65% by volume).
Listed as containing Sphagnum peat moss, composted bark fines, leaves, twigs, wood chips, etc. and "pasteurized poultry litter" (cooked chicken crap).
The chicken crap is cooked to eliminate the bacteria it's commonly known to contain. Using it I've never seen 'level' spikes to be concerned with. Several tanks went months without ever testing above zero or 5ppm on nitrate and phosphate but plant growth was outstanding.
0.10-0.05-0.05 is one of the lowest NPK ratios you will find on a bagged product and part of the reason the initial spikes reported by many using other stuff are reported at a minimum using MGOCPM.

Get the right bag and have zero point zero added chemical ferts to be concerned with. If you want to avoid ammonia spikes and other water parameter hiccups I suggest avoiding soils with manure in high percentage. Plant heavily with what you have. Root feeders right from the start, also I like to use floaters (you mentioned some) because they aid in controlling light and the filter feeding roots from floaters minimize anything left for algae to feed on. Stock lightly and control the light energy betting you no issues but can't guarantee anything.
Using seeded media (which you have) setting up over a dozen of these type tanking systems I've only tested positive for ammonia and nitrite on tested values twice. Both times in less than 48hrs it was over.
