Hello guys, I was wondering how many of you run the filtration in your sump. Im roughly new and I want to make sure my system is running perfect. Ive noticed that a few people run GFO, carbon and phosphate reactors. Some people use a bag of chemipure ect ect ect. My system simply goes down the overflow into a filter pad. Then through liverock into chaeto. Then off to the protein skimmer and back up to the aquarium. I do not run any carbon chemipure or anything. I dont think im happy with this because im starting to get a little red slime algae down in the sump where the live rock is and the chaeto. And I cant seem to get the nitrates do go any less then 40-80.
So if you guys dont mind can you give me a run down of how your system works and if you have any advise on my system I would greatly appreciate it.
