Reactor for 29 gallon sump less

[Joe37]

I have a 29 gallon standard tank with a reef octopus 100 job skimmer and an ac50 running purigen, carbon, and a filter sponge. i do 5 gallon water changes every other week, my tabk is only about 3-4 months old and the water is usable pretty clear. I've been thinking about getting either a bio pellet or phosban reactor for my tank, specifically the bio churn 90 hang on the back bio pellet reactor and the two little fishes phosban reactor 150. Could yall please give me advice on which one would be better for my tank and any other helpful information about them. Thanks

If you are trying to control phosphate, I'd just add some Phosguard to the activated carbon media. Water changes should be enough to control nitrate.
