Update for 19NOV:
Bought the last bag of sand at the lfs today, will get more tomorrow when their shipment comes in. Cut my substrate braces this afternoon and added them into the tough spots (hope they dont float when i fill the tank).
Tomorrow is a busy day. Getting my pump for the sump, and buying my media holder for the sump. Tank is really coming together and i can't wait to plant. Buying a new solenoid as well since i cant get the current one to seal properly. Redoing my leak test on the regulator (pressure hasnt changed in the last 24hrs, so its good)
