If you smart use the normal garden hose, with a water bed drainer and use it to suck out the fert tank. Watering you lawn with a little extra.
Putting in the tank will upset the normal groth of enzimes in the tank.
oldsanclem Reviewed by oldsanclem on . Septic tank, any probs dumping used nutes? I guess my heading really asks my question. I'm moving to a house which has a septic tank, and am wondering if I can cause damage to my septic system dumping it in there... I know I could pump it on the lawn, but I don't really want my neighbors to see me doing that... SN Rating: 5
