My nitrates are high - 40ppm. I had a small angel die about 2 months back but never found it to take it out. I also have a flower nem that is doing so hot. Not sure if I should yake it our or do water chnages. plan on water changes anyway but wanted to help lower the reading soon. So I figured water changes and a nitrate sponge to help speed up lowering that param. Any side affects I should be aware of using the nitrate sponge?
Thanks,
Mark
