Hi All,
Been keeping RCSs and Caridina Typus for some time now in a modified Aqua One AR850 (in the form of lighting and filtration). The following are the details:
Tank: Aqua One AR850 with matching cabinet.
Filtration: Aqua One Nautilus 1100 with bio balls, Japanese filter mat, coarse sponge, fine sponge and wool pad.
Lights: 4x 9W/1000lm offroad LED floodlights (gutted the floodlights and installed into the light hood along with RGB LEDs and 3x 40mm Noctua fans for cooling). 2 of the RGB LEDs also act as moonlight.
CO2: ISTA compact dual gauge regulator with integrated solenoid, ISTA BC, ISTA S/S check valve, Dupla check valve, DIY external reactor, 1L ISTA cylinder and 1L Up Aqua cylinder.
Heating: DIY external inline heater compartment housing Eheim Jager 250W heater.
Timers: Two DIY timer boxes from Jiffy project boxes, each containing two 7-day programmable timers with battery backup (no loss of time and program during power outtages). One for CO2, one for Main lights, one for fans and RGB lights, and one for moon-light.
Substrate: Plain inert gravel (with years worth of fish poop for nutrients), originally capped with quartz sand but has mixed in since then.
Ferts: Was using Dino Dung but now Osmocote aquatic tabs. Also does Dino Pee and Spit, and Seachem Flourish.
Auto Doser: Two pee/stool sample bottles using inline taps to dose diluted Dino Pee and Spit.
Fauna: 100+ RCSs, 6 Caridina Typus, 30 Cardinal Tetras and 7 Lemon Tetras, and lots of Ramshorn and Pond snails.
Flora: Staurogyne Repens, AR Mini, Subwassertang, Limnophila Aromatica, Anubias Barteri, Java Fern Windelow, Regular Java Fern, Crypt Wendti, Hygrophila Polysperma, Hygrophila Corymbosa, Hydrila Verticillata, Ludwigia Glandulosa, Ludwigia Repens, Crypt Balansae and Native Vallisneria.
Hardscape: 2 pieces of driftwood, toppled over one another (where the Subwassertang sits on).
Photo of how it was at the beginning (with fluros gutted out and using 5050SMM module LEDs):
Fitted the 4x CREE offroad LEDs (notice the narrow beams):
The beams were too narrow, even though they claim to be flood lights so I removed the lens otherwise I would have needed another 4 for the back:
I then gutted each CREE LED and mounted to a flat aluminium bar with SMD 5050 RGB LEDs and some 7000K Eagle Eye LEDs:
