Hello,
This is my first tank with C02 and so far it is 2 months old. I have some algae issues and so turned my lights down to 4/7 which is about 60PAR at the substrate. Im trying to get optimal C02 but it appears to be a bit of an art form. I gave up counting bubbles and let the water evapurate from that. Does below look normal? To me it seems like it is potentially inconsistent and slow to saturate. My fish seem totally fine btw with no change of behavour throughout the day.
Note readings are with a digital meter for PH and API test kit for KH.
7:00: ph6.9 / KH4 - C02 ON - (i think it used to be 7 before i increased injection to 6>8 hours. Appears effect not wore off from previous?)
8:00: ph6.6 - med green - LIGHTS ON
9:00: ph6.5 - med green
10:00 ph6.4 - med-light green
11:00 ph6.3 - lime green
12:00 ph6.3 - lime green
13:00 ph6.3 - lime green, nearly yellow
14:00 ph6.3 - lime green, nearly yellow
15:00 ph6.2/ KH4 - lime green, nearly yellow - C02 OFF .....
16:00 LIGHTS OFF
Equipment
oase scaperline 75l rimless with matching cabinet
Oase 350 biomaster (quite overfiltered)
Glass lilly pipes pointing slighty upwards, creating good agitation
Full strideways pressurized c02 system
C02art inline diffuser
Twinstar S light (new model)
Tropica substrate
8 ember tetras, 4 galaxy rasporas, 8 pygmy cory
Routine & levels
Light 8 hours a day 4/7 settings 60PAR reasing at substrate
C02 comes on 1 hour before light son/off 1 hour before lights out
TNC complete weekly dosing of 7ml
weekly water change of about 40% at which point nitrates are 10-20
Flourish excel currently dosing 2ml per day and 5 ml on water change
A number of bladder snails that were not invited but their shells turn pale quite quickly
