IMO you will always struggle with consistency with diy co2.All right guys, i'm at my wit's end, here.
I've had a DIY co2 , two bottle system set up for a few months now, and can not, for the life of me, manage to maintain a 2 BPS consistency. Any/all help is appreciated. Any formulas i should try, precautions, etc.
I have a low-med tech tank with:
Amazon sword, mini sword and melon sword
Fissidens and Flame moss
1 lowly crypt
Light is strip LED light and small 13W T2 CFL, 860 lumens, 6500k - they are on 8 hours a day.
The tank was doing well (plants even pearled by the end of the day), but I was dealing with some nutrient issues with my plants and purchased iron and fert tabs. They work WONDERS, but I now have a BBA and GDA outbreak and I can only imagine its because the plants are demanding more co2 and cannot out compete the algae.
I don't want to lose my fissidens or my sanity. Please help.
Here's what I have:
DIY Co2 caps/pressure systems seen here, for 2 bottles:
Professional D301 Aquarium Water Plants DIY CO2 Generator System Kit Fish Tank Accessory - Tmart
Drop checker in 2 liter soda bottle
Mix of blue co2 proof tubing and smaller, clear tubing
Check valves attached to both bottles, and tubing running to diffuser
Plastic 3-way divider for the airline tubing. Tried brass, somehow less effective.
THIS diffuser and THIS one. (used intermittently)
Yeast Recipe (and in order of how I mix):
2 cups granulated white sugar
mixed tepid/warm water with sugar + dechlorinator 3/4 the way up to the bottle
add 1/4 - 1/2 tsp active bread yeast (refrigerated) into shot glass with sugared water from bottle, mix until foamy
let sit for 5 minutes, add to bottle and shake
re-attach to cap
Each bottle is replaced once a week.
I turn the co2 off at night using the valve on the co2 kit here. It's turned on about 10-20 minutes before the lights go on in the morning.
Am I doing anything wrong, here? Or am I just cursed?
Thanks for taking the time to read through, I hope I can get some assistance!
