Whew !! getting into this website takes longer then building the tank !!!
The system has been running 12 weeks now .. been through the brown then green algae stage .. calc pink algae now gaining traction in the low light areas. fish load is still low at 11 goldies 4 tangs 4 wrasses 6 cardinals for now. Did my first water change 900l (7%) struggling to maintain calc and dkh @ 7 and above as the new lights are producing major calcification rates .. this should settle as the bulbs age a little.
The engine room is similar to previous only larger 4500l sump. I have a 900l settle out sump which doubles as the water change sump (it can be bypassed while making the RO water over night) .. it then overflows to a 1000l live rock refugium then to a 2000 litre DSB/coral quaranteen section . then last section for antiphos carbon and 2 return pumps. There is also 60kg of vertical aragonite which is used to co2 strip the calcium reactor and neutralize the denitrifier. The rest of the recirculation is drawn from the settling sump floor directly into the skimmer which then free flows back to the other side of the aquarium total flow 23500l per hour. I keep the head height btween the sump and tank at 750mm to maximize flow rates and power usage 400watts. A feed pump supplies flow to the carbon/antiphos reactors at 60l/hour .. the calcium reactor at 40l/hour and the fish quarantine set up tank 130l. This tank is disconected from the main system when new fish are added . it has its own trickle filter. the water is reduced to 50% salinity. When the fish are ready the flow is reconnected which brings the q.t. to tank conditions in about 5 hours.
Lighting on the SPS is 16 t5 (20k and 10k) 9 to 9pm. 2 x150w 13k 10 to 8.45pm and 8 X 250watt 16k 4 to 8.30pm. The lps side is similar but 14 T5s , 2X150watts and 5 X250watt halides. Flow in the tanks is 5x15000l prop pumps SPS and 3 x pumps on the LPS side all on a variable wave system with night slow down.
What else ... 15l kalkstrirrer set on intermittent night top of ..50l per day at the mo !! Hopefully comes down in summer
. Reefdoser adding strontium/trace/magnesium/iodine twice a day. Skimmer mazzei system 400l volume drawing 8000l air an hour .. does not skim at night 12 to 7 am . Electronics .. measure contnous PH and temp. MV controls the denitrifier in the correct oxygen zone and conductivity meter for salinty control .
Thanks Al for posting .. if you had left it to me ...???
Ps this IS my last tank .. promise
