High Tech 10G with lots of custom equipment and digital CO2 control
This tank has been planted for about 4 weeks now. I am just now starting to get the algae under control. I used established media to quickly cycle the tank. A few neon tetra were used as the ammonia source. No fish were lost during the cycle.
Filter: SunSun HW-302, one tray of pot scrubbers, one of Seachem Matrix, one of polishing pads
Tank: 10G Aqueon
Light: Custom reflector with 2x Cree CXA1512 LEDs, about 12W (1000 lumens or so), 5000K color temp
CO2 rig: Victor VTS 450 D with 10LBS CO2 cylinder, custom CO2 metering setup similar to CarbonDoser
CO2 diffuser: Custom inline reactor
Heater: Inline 100W
Substrate: Black Diamond Blasting Sand (Coal slag)
6x Neon Tetra
3x Amano Shrimp
Lots of snails
Dwarf Hair Grass
Several others (all from LFS)
I am by no means a plant expert. Maybe someone can tell me what I have?
The stem plants require trimming one or two times a week or they will reach the top of the tank. I bet they grow about 1" a day at times.
Four Osmocote+ root tabs
EI with dry salts + flourish comprehensive
50% weekly WC
About the custom equipment:
The black box with the LCD is the CO2 timer. It controls the clippard solenoid to produce fixed size large bubbles of about 1ml each. There is a knob to set the time between bubbles. Internally there is a PIC micro controller, an LCD, an encoder, a simple solenoid driver, and some power supply parts. It uses the PIC's internal EEPROM to remember the time setting.
The silver box houses a meanwell LED driver for the light on the tank. There is a pot that allows the current through the LEDs to be varied.
This is the all in one heater and CO2 reactor. The heater is sealed with a Heyco water tight cord grip. CO2 enters through the small hose at the bottom. Water flows down through the clear tube, over the horizontal heater and out through the hose on the left side.
There is no need for a needle valve because the volume of gas injected into the reactor is fixed by the geometry of the solenoid body.
