So my new filtration system will be as follows. I will have three main ways to export nutrients in my sump. First will be my skimmer, it's a simplicity skimmer with a dc pump it's rated for 60 to 120 gallons. Normally I always go a step or two above recommendations on my skimmer but I think it will be fine incorporated with my other filtration. Next I have a refugium, I'm using the eshopps curve light only cause I got a really good deal on one I would have been fine just mounting any old light from the hardware store. My last tank had a floresent 6500k light from Wallmart and it worked great. I will be growing cheto and Cullerpa harvesting it as needed. I went with rubble rock in the fuge. I didn't want to use sand, I think rock is much easier and cleaner. I was thinking about going with mud. I know people who use miracle mud and swear by it and I've also talked to people who tell me it did nothing for them. Mud is something I may try later. Last I will be using a HOG .5 upflow algae scrubber. I sold mine to a friend the last time I took my tank down. He had it laying around in his garage and gave it to me. I am a big fan of algae scrubbers,, I hope it works well on this tank. The great thing about a scrubber is you can't over use it. If there are little to no nutrients in your tank the algae just grows slower. So that's my nutrient export system. I will still do my water changes.this time I will be doing a lot of testing on my tank. I may take cetain items off line for a while and see how they effect water chemistry, coral growth and over all tank health. I will be running a pretty heavy bio load for a 60 gallon so it will be putting all these systems to the test. Everything should be installed and running by the end of the week
