Is the tank drilled?
careful with the dripwalls. I used to have them, but I tore them down as they can really rot the plants and get clogged. my only dripwall tank right now is my mantella tank. I do not get good growth wherever there's a drip wall. Plants tend to grow better just by passive capilary action of a cocopanel sucking up moisture from the soil. The best way is to get your tank drilled, like my tank acrylic cube is and use a sump. Cut a hole in the top of the hood to put the T pipe through and cut holes in the tube so it drips along the back wall. I have done most of my drip walls this way. A prefilter is important for your pump because junk can get up into the pipes and clog the holes.
One good pump I recommend is Maxi-jet, mostly because they have a prefilter. Mini-jets are junk, just forget using them. A maxi is one of the best pumps, but they are big.
I highly recommend getting the tank drilled. It is a real pain trying to tear up a false bottom trying to unclog a pump. I have never really had to unclog my maxijet on my mantella's drip wall, and all I need to do is siphon the extra water out for changes or just pull it out to refill it.
You can put chillers and heaters in a sump as well.
