Re:90G set up for mandarin,seahorse,coral system etc?

Thank’s for your very informative advice 😉

I have set up a 3 month old 90lbs LR 4"-6" dsb 90G 48"Lx18W"x24"H 8-t5 H.O on the blue side 4" from water level with 30G sump over fow box in the middle back I have a single pipe lift pump that is approx 600-800gph that is "T" off in the back split into 2 pipe’s on each side of the over flow box that is brought down behind the rock’s and under the gravel in the front of the display "T" off again the 2 pipes into a total of 4 output’s I think is 3/4" wide each was thinking of 3 hydor koralia power head’s

2 will be 600gph and 1-400gph

was hoping this might be ok for seahorses?

I have some question’s regarding lower light and nutrient’s in regard’s to sps
not sure what to believe when I go on other forum’s they usualy call me nut’s to suggest that an increase in nutrient’s may fill in surton spot’s where light is lower in regard’s to say montipara digitata/cap sps not sure If it’s possible but would like to play with the concept all the sps will be in the top 1/2

Do you have a suggestion’s on forum’s in regard’s to lower light/flow extra nutrient’s

Thank’s
