Hiya
I’ve got my tank set up and it’s currently cycling. However I’ve noticed in the filter compartment there’s space for some additional media or product of some kind. See photo below- I’ve circled the two sections of space. One is below the existing filter media, the other is below the skimmer.
Does any one have any suggestions what I could buy to put in here to aid my filtration? Ideally that won’t break the bank.
I’d be particularly interested in anything that has a good success rate of reducing nitrates.
Thank you!
