Well…any suggestions? My 40 litre paro tank is filtered by plants and thus no nitrate ever forms (and the ammonia is all devoured by the plants), but nitrogenous waste is not the only thing fish produce…
Guess I’ll try to do that, thankx…more thinking other dissolved compounds, though (or do they just degrade into ammonium?)
Any chemical compounds in the water will be taken care of if you do enough water changes, perhaps twice a week at least if you aren’t using a filter.
BillOK. Just a question, but…if it’s not a direct part of the nitrogen cycle (in which case the plants would devour it) would a filter really do anything? (I was under the impression that most forms of chemical filtration would be quickly overwhelmed trying to absorb the tannins)
I don’t think there is any real answer to your question as it is. What exactly is the chemical you want to remove?
I’m not a chemist, but as I see it, trying to find sufficient plant growth under such conditions is like trying to use a biological filter. Hence the reason I, and a lot of others, choose not to grow plants in the breeding tanks, also relying on plenty weekly water changes instead of using filters and everything works out fine. I’m not anti-filter, but I prefer to breed all my fish without. Bettas, Gourami, Killifish, Macropodus etc.
If you are having a problem with a pollutant in your tanks you need to identify it and treat it as required. If you are merely talking about a “what if” scenario, then there is no answer unless you can be more definitive.
Personally, I do water changes 3 times a week, in between water changes I vacuum the solids out thereby giving extra small water changes.
I would avoid having “what if” scenarios, they might never happen and you will lose valuable time studying your fishes actual needs.
