You could also get one of those mesh bags, I think they used to sell them for aqua clear filters, or use old nylons, or something similar, stuff it with peat, and stick it in your filter (or sump or something).

It will get exhausted and need changing periodically, and need some experimentation to determine what amount you need to get the results you desire, but it's pretty low-effort, and inexpensive as well.
