Definitely would need that to be looked into if that is a correct reading!!
Assuming nitrates are present in your water at an elevated level you could use plant filtration for your tanks. There are some threads about it, but one of the most basic ways is to use pothos plants and submerge the roots (keeping the leaves out of the water). You will probably need a number of these to really make a difference, but definitely worth a try. The more leaves the better.
When I am able to set my tanks back up (after my wife and I buy a house) I am planning on putting plants in my wet/dry filter with a light in the stand. This way I don't have plants growing everywhere out of the tank!
