I'm sure your ammonia problems had everything to do with the removal of your
filter & bacteria & nothing to do with your peat substrate. Peat does not
contain much available nitrogen.

It would be good to have Swords & heavy root feeders to help supply oxygen
to the substrate. Fast growers will take care of any ammonia production by
the fish & you should never get enough nitrate for ammonia production in the

If the plants are growing well, don't change the substrate. If the fish are
having problems, check your water parameters for ammonia. Perhaps you have
too many fish or feeding too much for the size of your plant population.
Once things grow in, it should be much better.

Where do you live that you need to use a fan? I'm guessing SE Asia? Nice to
be able to have aquariums outdoors there! much cheaper using sunlight & no
heaters! I've even seen continuous water supply systems that worked great!
