i would do a fuge/sump if you can fit it in.. measure the biggest size aquarium you can fit under your tank.. then decide on what skimmer you want.. imo .. most hob skimmers are junk.. they have too small of a reaction chamber... you get a lot more for the buck on in/external skimmers...
i would simply get 2 48'' t5 retro if i where to do a fowlr.. if i where to do coral i would do 4 either 2 48'' t5 and 4 400 se mh... ( i just like 400 but 250 would work fine)

few q?.... how are you going to change your airstones when they go bad??? and do that air pump pump in hot air?? ( cuzz of the compression of the air.. some pumps pump hot air which can lead to higher tank temp)

i just add 16 tsp to my 13 gal top off tank... mix for 20 min and just top off as is... took me a little while to figure out how many tsp i need to keep on top of the damand but im good now... ( i started off at 1 tsp per gal... once mixed i did not added more... aggitating the kalk mixed...
test you ph and alk.. if they are in line then just dose the alk till the calk is in range again. then, dose in equal parts again.. just dont do anything to drastic to the water parm... if you are werry.. do a cuple of small WC till you are in range again..

you should keep salt creep down to a min.. anything that salt froma salt creep lands on is gonna die.. just wipe things down once in a while and you will be ok..

im no pro at SPS but.. can you also list if you did anything to your water lately??? dose?? started using phosphate remover?? or whatnots... most RTN that i read about happens becuase a sudden change in alk...

you dont need to overdrive them.. but, since you already have the ballast might as well use it... all you need are 4 36'' t5 and you should be able to grow anything.. well except softies and such.. thwy cant handle that much light unless you acclamte them over a good time... im growing lps on...
actually, SLR are still the best retro reflectors.. the tek II was a wast.. they produce less par than the tek I .... they just spread the light out more.. but we need umph not distibution...
get the IC.. they are a lot better...

maybe too late but 6 bulb is the max of t5ho you will need for that tank.. t5ho are stronger then you think... imo the best bang for the buck... if you and lps,zoos and shroom is all that you want then id go with a 4 bulb set with SLR... no need to overdrive... ( i think a 4 bulb 4'' t5ho...
fill main display till it is at the point that the overflow starts to overflow.. then fill the sump almost full ( like 2'' or 2.2'' before it overflow and thats all the water you system can handle.. so just plug in the return pump and adjust the pump so that it down pump fster that the...
t5 dont run that cool... i would say my 6 54watt t5s put out as much heat as my 400 watt MH... do you have fans blowing in and out??? if all are just in or out then they dont doo much.. you need both... if you can make the out fan the one that is higher in the canopy... imo if the...
imo in the order of importance for sps are: water chem, lighting, flow..... most important in chem is alk then calk, then everything els is even... ( i would get 4 54 watt t5ho w/ SLR for a 55 gal... no need to overdrive)

you can run your machanical filters if you want ( skimmer / anything with filter floss but thats about it... no need to run any powerheads... just the main pump is all that is needed

i use 2 part system on my tank.. it's totally DIY and have been researched by PHD Randy Holmes Farly... he just got a award at MACNA... i use dowflakes ( ice melter and dust control... can be had for $10 or so for 50lbs) and A&H baking soda.. i adjsut my water with either parts till they are...
dripping kalk ( lime water... mrs wages pikling lime) adds both calcium and alk in equal amount... but if you just want to dose alk.. you cane use A&H baking soda... you can bake it for 1 hr at 400 deg first ( rids of moister) and can raise PH lvl if you also have low PH... google 'diy 2 part...
well your other design would still work.. just that you would have to flip it 180.. ( so as if we where looking at it on the other side )
i agree with the beat the bubble before rather than after but i dont think the triple baffle buble trap is always needed... as long as the baffles are not...
