Hello, after reading dozens of topics on this forum I have improved but I am still unable to manage BBA even with excel, so I guess there is a problem of CO2, I have a 1500l/h pump in a 51l tank that sucks water and rejects it via a spray bar, I have left 6 holes, the rejection is relatively powerful, all plants move quietly, the levels of CO2 are good "almost yellow", the pH drops one point at the end of the day I use the estimated index method with the dosages advised in the tutorial of the site made by "Ceg" I believe i just reduced to my tank volume.
In lighting, I use 2*24w t5 HO, I put the ramp at 50cm height, which makes that the bulbs are at 80 cm of the substrate, before that it was at 55cm of the substrate, I can deactivate a tube, but the rendering is really horrible, I have the possibility of rising the ramp.
As you can see on the video, the pogostemon stellatus is growing very well, something that was impossible before, the cuba was very nice, I pruned it, I think it has a problem probably due to the CO2 ?
can you suggest me some ideas to improve the co2, etc? thank you
