I really don't know much about LED and what Lumens you need to support plant growth. Soo I can't really help there but as for floating plants in general Water sprite, Duckweed, Frogbit work good. There are others as well. Have a look at the Fish profiles at the top of the page there is a section in there about plants and its broken down into rooted plants, floating plants, stems, and non substrate rooted plants I believe. It will give ya some I deals. Also if you can catch JDM I believe he uses LEDs and might be able to help with figuring out what plants you could have.

At some point you may need to address pre-filtering or an alternative for your source water.

In the meantime, Prime gives you some advantage in the temporary detox, but this will only work as long as you do 50% (or so) water changes at least every 2 days.

You might also find value in using API Nitra-Zorb in your filter. Nitra-Zorb is a 'scavenger' resin that adsorbs ammonia, nitrite and nitrate. It can be recharged many times with ordinary non-iodized salt.
...Or, another product that looks very intriguing is API Bio-Chem Zorb. It contains additional 'scavenger' resins that adsorb and remove a wide range of pollutants and toxins.
(In your case, I'd likely go with a pouch of Nitra-Zorb and assuming you have municipal water with chlorine/chloramine, only use the Prime to condition the amount of water in your water change. (For now, I would refill using 5g buckets. For Prime, using a childs medicine dropper, it's 2 drops per gallon. 10 drops in 5g - mix well.) If you continue to fill in the aquarium, add 1 capful before refilling for a 55g aquarium.

Also as boredom pointed out, this post may be worth a read if you haven't already: http://www.tropicalfishkeeping.com/f...-water-156489/

Good luck and keep us posted.

I think you all are missing something here. You are talking about ways of solving Nitrates but Nitrites are the killer issue here. 5 ppm Nitrates from tap are nothing to worry about ... but 2-5 ppm Nitrites is instantly lethal!

Something like Nitra-Zorb is necessary, but I would strongly agree with Abby that you may want to look into pre-filtering. Going to a full reverse osmosis system may not be necessary, but you can't keep adding source water that contains that much Nitrite.

Please note: Although I use it primarily for nitrates, API Nitra-Zorb also claims to be effective in adsorbing ammonia and nitrites as well as nitrates.
Although I suggested pre-filtering, it would also be effective in the tank filter.

I'm thinking that once the bio-filter is working again and smaller volumes are used for routine partial water changes, the combination of Prime, Nitra-Zorb and bio-filtration just may be the ticket to water quality...and pre-filtering, although I think advisable, may or may not be necessary.

The EPA has a standard of 1ppm as a safe drinking water .... here's an excerpt and a link:

"The MCLG for nitrite is 1 mg/L or 1 ppm. EPA has set this level of protection based on the best available science to prevent potential health problems. EPA has set an enforceable regulation for nitrite, called a maximum contaminant level (MCL), at 1 mg/L or 1 ppm. MCLs are set as close to the health goals as possible, considering cost, benefits and the ability of public water systems to detect and remove contaminants using suitable treatment technologies. In this case, the MCL equals the MCLG, because analytical methods or treatment technology do not pose any limitation."
EPA Nitrite regs

I'd be concerned about more than the fish here.

Jeff.

I hope the testing results were wrong. I am going to retest the sink water and hopefully get better numbers. Now I am scared for my family. If I get the same results, should I contact the city?

Perhaps get a quick second opinion, take it to a fish store (most test for free). If they also get those readings for Nitrites I would definitely contact your water utility.

Not to be a fear monger.... I would contact them anyway even after testing it yourself again and getting a favourable result as you won't know which test was accurate. The city can test the water more accurately and is responsible to be doing so on a regular basis. I would consider that this is not only your problem as nitrites that high almost certainly cannot happen in just one household on a water grid.

Get them to check it for you.

Hopefully it was just the test strips and someone can gloat at Mitch sometime about their accuracy.

Jeff.

Sorry for the late update. The water is atrocious. I have put in NitraZorb into my canister filter. I have also added duckweed and hornwort to my tank. I had also bought Tetramin Bacteria for a 75 gallon and did a 25% water change and added that. The fish seem to be doing a lot better. When I get home from work, I will be doing another small water change and testing the water. My fish are no longer at the top. The angelfish are acting a little weird but the rams, plecos, and tetras are breathing fine again. I will try to snap some pictures today.

First, what happened with the Nitrites in the water test?

Good that there is a change in the fish behaviour for the better.

Tetramin Bacteria? Why?
