This unit has plenty of flow, 120 LPM or 3.5 CFM but has limitations of only providing you 4 PSI of maximum pressure. The 60 LPM unit can really give you 6 PSI so it might be the better option in deeper ponds, make sure you check your tubing lengths and diffuser resistance before buying your compressor.
