Hey guys over the last few day my house has a odor of feet It started when I added my new larger sump. The water parems are good Amm-O, Nitites-O, Nitrates are a little higher because it is a FOWLR. After sniffing around I figured out the source of the smell is not the water or the sump. ITs the protein skimmer. I have a Octopus skimmer and their lids have 4 vent holes that release the gasses that im smelling though out my entire house. I love this skimmer because it does a heck of a job but can I cover up these holes?

Thanks

Ray
