I have to respond to this post (I joined the forum just to respond). I have 2 betta tanks, a 5 gallon and a 10 gallon (for a giant betta), with 1 fish in each tank. Silk plants. Water temp 78.8 degrees. 2 Aquarium Co-op nano sponge filters in each tank.
The tanks are both cycled and have 0 ammonia, 0 nitrite, a ph of around 7.4, and, up until a few weeks ago nitrates of 5-7.5ppm-15ppm (max). Herein lies the rub...my TAP water has a nitrate level of around 5-7.5ppm. I just reconfirmed/tested it. So obviously just doing water changes, no matter how frequently, wasn't going to do anything to lower the nitrates below 5-7.5ppm because my tap water had a bottom ceiling of 5-7.5ppm. (Water changes would and did obviously lower the 15ppm level, but only to the tap water ceiling minimum.)
Last week my giant betta got a little feisty and decided to jump out of his tank during feeding time (I have a glass top on both tanks but lifted up the lid to feed him and he got a little too excited.) I was able to quickly get him back into his tank but freaked when I read that he probably lost a lot of his slime coating as a result of the fall. So I ran up to Petco and grabbed a bottle of API Stress Coat (up until that point I'd been using Prime.) I did a 50% water change but instead of using Prime I used API Stress Coat.
Also, in the 5 gallon tank my rose petal guy had either ornament-related torn fins, self-inflicted/bitten torn fins, or fin rot. This occurred a few weeks ago and I'd started a regimen of daily 50% water changes, even though, to my mind, it was pointless because the water parameters were already spot-on. Since I'd gotten the Stress Coat I decided to use it instead of the Prime to see if that would help with his fin regrowth, so the last couple of water changes involved Stress Coat instead of Prime.
Yesterday I tested the 5 gallon tank for nitrates. For the first time EVER the level was at 0-2ppm, instead of 5-7.5ppm. I figured I did something wrong with the chemicals/testing so I repeated it. Again...0-2ppm for nitrates.
Today I did a 40% water change today in the 10 gallon tank, waited an hour or so, and tested for nitrates. 0-2ppm! I was thinking...WTH?!!! So I just re-tested my tap water to see if maybe something had changed, but nothing had changed; it's still 5-7.5ppm for nitrates. The ONLY difference was the Stress Coat.
So I Googled to see if somehow Stress Coat helped in the reduction of nitrates and found this thread. I know this is only anecdotal "evidence" and not scientific in any way, but there is no doubt that:
1. My tap water is a constant 5-7.5ppm for nitrates.
2. Up until I started using Stress Coat the lowest reading I found for nitrates was 5-7.5ppm.
What I don't know is if this is a temporary reduction or not. But still, I'm much more in favor of a lower nitrate level so I intend to keep using the Stress Coat and do daily nitrate readings to monitor it closely. (I have Seacham alerts for ph and ammonia to monitor those levels, and Red Sea tests for nitrite and nitrate.)
NOTE: I had been doing weekly H2O changes in the 10 gallon tank and twice a week changes in the 5 gallon tank. But now I think I'll up the rate in the 10 gallon tank to twice a week and the 5 gallon tank to 3 times a week. It's no big deal and I think it'll help the fish out. (I pre-heat the water in 5 gallon Home Depot buckets to match the tank temperature of 78.8. and pour the new water in using a 4 cup measuring cup to try to make the water changes as stress free as possible. Then I feed them so they associate a good thing with the somewhat disruptive water changes. They are extremely food-driven so now they appear to look forward to the water changes.)
