Hi, I do have a current thread about my CO2 setup but so not to be confusing I thought that I would start another for this particular poser!
I am using co2 and maybe I have got the wrong idea!
I have my CO2 starting 2 hours before lights on and the lights are then on for 8 hours. I have the co2 switch off 1 hr before the lights go off.
If I check the colour of my drop checker when the lights first come on then the colour is green but on the blue side. The ph is between 6.8 and 7ppm. After two hours of the lights on the colour starts going a lighter green and eventually to a nice lime green and the ph drops to 6.6ppm.
Hi SO19, I am due a water change tomorrow so you suggest me dosing TNC 8ml per day? I assume I will have to up the amount of my weekly change from 30% ? say to 50%?
I will remove my reflectors tomorrow......but.....my red plants look lovely and very,very red at the moment!! As I have changed the diffuser I will have to fiddle with the bubble counter until I get the lovely green colour back! Then I promise to leave it alone. Then if that lot does not help I will try and adjust the flow.
Thanks for that. I must update my photo as It has changed significantly with plants etc.
Well my lighting is not that high I have 2 x 45w T5 tubes with reflectors! I also only have one vallis in my tank amongst a load of other plants.
I have upped the bubble rate to about 8 per second and they seem to be tolerating it, with a nice green colour in my drop checker.
I am not sure that this reactor/diffuser is working as it should as there is a load of CO2 in the top end and the impellers seem to now have altered the way it is coping with the CO2. Difficult to explain but something has changed and I am not sure that it is big enough at about 6 or 7 inches.
I am really wondering whether it would be better with an ordinary diffuser?
I installed a CO2 pressurised setup last Thursday and have gradually upped the bubble rate.
I am now injecting 6 buubles per second and have a nice green colour in my drop checker. The plants are not pearling and I was told that there was not enough CO2. I upped the bubble rate to 7/8 per second but then the fish started to hang around the top of the tank. I reverted back to 6 per second and they stopped hanging at the top. The ph has dropped now to 6.8/7ppm.
I do not know whether it takes a week or two before plants start pearling or whether it is only certain plants.
The other thing is that the black algae appears to be coming back...but it appears to be only at the very front of the tank and on the gravel, not masses of it but enough to annoy.
I have good circulation and flow now. I have an Eheim pro3 250, a new wave circulating at 800 lph pointing to the front but I can up it to 1600 lph (on the higher rate the plants really lean over.
I am also using a reactor/diffuser run via a small submersible pump at 300lph but I believe it is more likely 200lph.
I am wondering if I swapped the in tank diffuser for a glass ceramic one I would get better results and use the small submersible to add more to the flow.
I am concerned about this re-appearance of black algae although I would not describe it as bba taking into account the pictures of black hair algae that I have seen. It is more like black dirt! but it is not dirt obviously.
My thinking is that by using a ceramic diffuser it may ensure more CO2 may reach the plants. I am new to CO2 this and clutching at straws really.
