I think the mistake you are making is that you are relying on a nitrate test kit to tell you whether you need to dose nitrates. If you have calibrated the test kit, you can do that, but if not, you...

If the tank is 10" x 10" x 15", it is a 6.5 gallon tank, not a 15 gallon tank. For that size there are several clip on lights that could work.

Dosing 3X the recommended daily dosages, once a week, in the EI dosing scheme isn't likely to cause any overdosing problems. It takes a lot more than that to cause problems.
