That will help. If you need more, then storage containers or the shorty rubber made stock tanks work well beside the sump... bulkhead in one side to empty into the sump. Any size is better than nothing, but you might need more area than that, although it does not look small.
A guy on here used a handful of 5g buckets in parallel and his nitrates are going down. There is some stupidity in this thread by some of the usual suspects, but check out the downward trend by the OP. These things can work if you have enough surface area and give them some time:

Anyway, I hope that this helps.
