The presence of nitrates is symptomatic of an algae bloom but not the cause of it. If there is more ammonium present than the plants can use, the In my experience, nitrate level itself is un-related to an algae bloom. In my tank, the rate of nitrogen production is higher than the plants can use, so the nitrate level in my tank constantly rises. But, because of the massive biological filtration capacity of a wet/dry filter, the ammonia is converted QUICKLY into nitrite/nitrate. In my 10g quarentine tank, with no fish in it, if I add lots of KNO3, to get a nitrate level of 50ppm, I get no algae bloom except for an increase in green-spot algae on the glass. I've held the nitrate level steady at 50+ for over a week testing this. If do a 100% water change, and then add enough ammonia to reach 10ppm ammonia, I'll have algae soup in just a day or two. Algae seems to be able to utilize ammonia MUCH more efficiently than it does nitrate. Chuck Gadd http://www.csd.net/~cgadd/aqua |
