i am the petstore aqua keeper i have 5- 800L tanks and all reading realy high. i do a 25% water change on all my tanks every week and prime them daily from water evp and loss.
i will test them again. how bad is it for the fish to have nitrate lvls this high?
and i am useing the master test kit XD
Plant's that are thriving will help lower nitrate level's.hi guys/ gals me again. i have tested the lvls in my normal water supply and there showing between 0ppm so i think somthing is wrong with my water. i will start doing a 25% water change 3 times a week starting today to try and decreass the nitraste lvls.
in the tanks i have alot of diffrent plants some in great health some in realy poor. will having more plantys in my tanks increase or decrease nitrate lvls. i will cut down on feeding aswell.
if anyone has any other ideas please let me know asap.
I believe 20 to 40 ppm Nitrate reading while not being perhap's a magic number,, will be acceptable for the health of most fishes we keep.There is no magic number for nitrates; the goal is to keep nitrates low, as low as possible, and as close to zero as possible. Nitrate is a toxic substance to all fish. Some species tolerate higher levels than others, but long-term nitrate is harmful. None of the fish we maintain in aquaria live in natural habitats with nitrate levels much above zero, which should tell us something.
You haven't given us the nitrate number for your source water (presumably tap water), and if this is the issue or part of it, there are ways to handle it. If the nitrate is partially or solely occurring within the aquaria, then increasing water changes [50% weekly], lessening the fish density, curtailing feeding and having live plants that are relatively fast-growing (stem and floating plants are ideal) are all ways of handling it. I realize that if these are store tanks, you are under situations that would not be encountered by home aquarists, but the same practices apply.
