Thats interesting that you couldn't keep up with pods.
I personally am finding it easy, I have a RS max nano with 7/8 fish (2/3 wrasses, 4 gobies and a blenny). 6 of them will eat pods, those six include a Griessinger Goby, Blue Star Leopard Wrasse, Hector's Goby, Naoko's Fairy Wrasse, Pink Streak Wrasse?, Yasha Goby. Most weeks for the past year I have added pods but when we had a shortage for 2/3 months there was still a thriving population. This is extremely similar to my 4' tank. The thing that helped me to accomplish this in only a year was actually having rocks that were from my first ever reef tank 15-20 years ago.
IMHO, it shouldn't be too hard unless you have an immature tank to keep up on pods. but that is based on my experience with reef tanks.
