Very much possible. Since you are saying that the water in the tub is also getting nitrate upto 15 in a week, so the rocks are the main criminal I presume

Have you considered introducing a nuisance algae problem to the tank?
Keeps my nitrates down...

How long have you had the tank running. How old is the rock

[makana]

The tank is roughly 4 years old as is the rock. There are currently two types of nuisance algae in there.

Any ideas on what I can do? Throw in the towel?

I'm not sure if they make towels that absorb nitrates. Wait, do they? That would be totally awesome!!

Anyway, have you considered trying BioPellets in a reactor? If set up properly they can do a great job at reducing nitrates.

..seriously do they make nitrate absorbing towels?

Do you have any dead spots in the tank or detrus build ups in the tank

4 years could mean 4 years of detirius buildup in the rocks , you could try taking one rock out at a time and bleaching them then re add to the tank (slowly of course).Bleach eats all the organics in the rocks that could be causing your nitrates.

To give an alternate to toytech's post take a turkey baster or a big syringe to blast off a bit at a time to keep from continually restarting to tank by cleaning the rock heavily like that
