Hey guys. im experimenting with my DIY CO2
... My first bottle seemed to have run out of juice after only 4 days.. I think I might have put too much yeast in because when I first made it I was getting like 2-3 bubbles per second.. Now I cut back on yeast and its more like 1 bubble per second..
Im doing the PH/KH
method of reading CO2
.. and the issue im having is the water on top of the tank if I turn my airstone off gets a nasty film on it.. and I can see the Tiny CO2
bubbles collecting on top and not poping because of it.. Im using my powerhead with a small airstone underneath to diffuse my co2
.. The powerhead turns the bubbles into thousands of tiny bubbles and spreads them all in my tank.. So im thinking if I leave this film on top my tank wont have enough O2
for my fish to breath...
So I turned my O2
airstone (not the co2
one) airstone on with the co2
running and measured my PH and KH
after 3-4 hours. KH
was 4 drops it seemed to have dropped I dunno why, it was 6 drops 4 days ago when I started this.. The PH looks like it is 7.0 or 6.8 I cant tell.... According to the CO2
chart that means my CO2
levels are 19ppm if its 6.8 or 12ppm if its 7.0.. Is this enough CO2
for my plants or no ?
I turned the airstone off just now and im going to test the ph and KH
again in a few hours to see how much the CO2
increases to and I'll let you guys know... Prior when I had my old CO2
bottle of 2-3 bubbles per second with my airstone off my PH was around 6.6-6.8 and my KH
was 6 drops.. My CO2
was according to the chart around 48PPM and I noticed fish gasping so it was too high
Its just really hard to read the PH on this chart once its in the 6.6-7.0 range
Here is a picture what does the PH look like to you ?
