Look dont freak about the chemistry of your tank. It sounds like you may be stocking it a little to fast. You have plants thats great, but what you need is a power filter with a bio wheel. So leave the tank alone for atleast a month let the water get use to having so many fish in it, if you add fish to quickly you will have chemistry problems. When you do start adding fish do it one at a time once a week give the microbs in the water time to adjust to the added waste. Inch of fish per gallon and put as many plants in there as you can fit. Id have to agree with the last post for your community
