I have a question about filtration.
Currently, I have a powerhead from ZooMed "powersweep" and a pengiun bio-wheel 200. I have been having hard time trying to increase my CO2 level in my 29g using Hagen ladder. I have the diffuser attached to the tubing and allow the bubbles travel upward below my powerhead. Refer to other thread I posted... theres a picture of my tank in there... https://www.aquaticplantcentral.com/f...substrate.html
I have no idea whether if its due to my biowheel or due to my high KH level. (I opted to post this in equipment forum)
I recently tested my water and the parameter is as the following:
Ammonia: 0 ppm
Nitrite: 0 ppm
pH: either 7.9 or 7.7 (the color chart is very difficult to read)
GH: 280 ppm --> 15.68 degree
KH: 100 ppm --> 5.6 degree
The pH and KH readings tells me either I have 2.115 or 3.352 ppm of CO2 in my 29g.
So what is stopping my tank from having higher level of CO2?
If I was to remove my HOB and add better sponge filter to my powerhead... can I use the powerhead as the sole filtration for my 29g?
Just so you guys know, I've already added the foam to the HOB reduce the surface agitation at the output.
Or will I better off 'revamping' my pengiun and then get rid of the wheel?
