In general, I would not use any product that removes ammonia because this is the plants' preferred source of nitrogen and they can take up a lot of it.

However, in a new tank with few or no plants, yes. But you now have plants and this tank has been running a couple weeks, so I would not.

Third point. Depends upon how the ammonia removal occurs. If the product detoxifies ammonia by changing it to ammonium, that will not hurt; water conditioners that detoxify ammonia work like this, and some other products do too. The plants need ammonium, they can receive it by changing ammonia themselves, or in acidic water ammonia automatically changes to ammonium. The nitrosomonas bacteria use ammonia/ammonium, which ever is present, equally. So no issue here. [Remember, ammonia and ammonium both read as "ammonia" with our test kits.] But if the product does actually remove it completely, I would not. I have seen claims from some products that they do this, but I've no idea if this is true or not. But if they say it, I wouldn't risk it. Anything chemical or artificial that messes with an aquariums bacteria and biological balance is not generally advisable.

thank you. i will stay clear of this. this tank hasn't been running for that long. but i don't want to starve my plants either. i am not 100 percent sure how it changes the ammonia and i don't want to just change it and not actually fix the problem. i am continuing the water changes. also i have turned back on the power filter as my heater is not reaching the other side of my tank without it. so i have turned it on and put it down to the lowest setting. will this make a bad effect?

No, but it will not do much good either.

As for the heater, I have quite distinct thermal zones in all my tanks and the fish seem fine. When I do a water change and start pruning or moving plants on the substrate I can detect a cooler zone than even a few inches above. And this is constant. I place my heaters next to the filter intake and outflow in larger tanks (with two heaters) or next to the outflow in smaller. With your undergravel, you have a return stem, I would put the heater near this.

try turning your heater diagonally or horizontal, if it is completely submersible. Eventually the temperature in the tank will normalize.

What happens in tanks without heavy currents, is the heat rises, and shuts off the thermostat at the top of the heater, prematurely. By tilting the heater, it allows the heater to run longer before it tricks itself into shutting off.

my 20 long has almost no water current, and the heat is just as even as it should be.
