i have a 130 gallon set-up mixt with 50/50 lps and sps and i do exactly like that,i have lots of fish feed them like crazy so they look like pigs,about 4-5 times a day 2 of them with brine and mysis shrimp and another 2-3 of pellets,i think does help having the tank next to my couch
),and my nitrates are about 20 ppm and my sps grow like crazy some off them doubled the size in one month...i think this is a good thing,as my fish are fat and healty and the corals love it.all i do is a water chance every two weeks of 20 gallons and a good skimmer..
