Hey all - My planted discus tank is coming along well - However there is a chance I'll be going medium light by adding another fixture, and was contemplating CO2 for more than one reason:
Can I get confirmation on the below facts:
Questions:
A lot of questions - Hopefully the use of snazzy bullet points makes this easy to follow!
Thank you guys (and gals)
P.S. Heres a picture of the tank so far.
Can I get confirmation on the below facts:
- CO2 Lowers PH - Correct?
- This lowering of the PH is unstable, and quickly crash/spikes if CO2 dosing changes
- Discus like a PH lower than 7.5
- My tank is at 83-84 degrees
- 75 gallon (4 foot)
- Fluval 304, 300 watt heater
- Nitrates are never above 5ppm
- Its becoming moderately planted, with places to hide growing out
- The tank mates are acclimated to warm temperatures.
- PH is 8.2, with driftwood in tank
- 54 watt 6700k T5 + localized 96watt PC 50/50 bulb
- If CO2 is an option, looking to get a 108 watt T5H0 with the 54 T5 watt for a total of 162 watts if i Go to CO2)
- Eco Complete Substrate
- My standing (1 week) tapwater PH is 8.4
- My tank PH is 8.2
Questions:
- is dosing CO2 a valid option to lower PH on a permenant basis?
- warm temperature+CO2 = Oxygen content being low?
- Will Dosing CO2 mean that I will have to do many small water changes to I don't get PH spikes when adding new 8.4 PH water?
- When I first pour tap water, its around 8.2. Standing it goes to 8.4 Would it be best to put in "fresh" dechlorinated tap water?
- is 160 watts enough to grow medium-high light plants and not annoy discus?
A lot of questions - Hopefully the use of snazzy bullet points makes this easy to follow!
