For flow, I use the volume of the tank times 50 as a rule of thumb when determining the gph for a tank. For my 150 growout, I blew that out and was running 8800 gph. The tigers were hppy as a pig in poop.
The drip would be a good idea. I've found tigers to be fairly adaptable as far as hardness and ph, but they do NOT tolerate nitrite or nitrate. Mine would normally stop eating well when no2 or no3 got UP to as LOW as 15-20 ppm. I did regular 50% WC and I had a thriving, large pothos colony. I'd have set up a drip in a heartbeat if I had the means to do so at th time.
