Hi all
after some help and advice please. I have been toying with co2 again lately after 3-4 failed attempts in the past and failing again!
first of all about the tank
5’x18”x2’ deep
Fluval fx5 with 4.5” spray bar
Home made inline diffuser using water filter housing on Fluval outlet (have also tried inlet in the past) Iv also made different diffusers in the past of various sizes but this gives the best results.
wave maker for extra circulation
2x Fluval planted led 10 hour cycle with slow 2 hour ramp up and down.
it seems nothing I do can turn the drop checker green.
Iv turned up the bubbles per second so they are too fast to count (more than 6-8)
I have turned them down to 3-4 and left it on for longer (5 hours before lights once)
Iv put it at 2bbs and left it on 24/7
Iv tried in tank diffusers x2 one at each end
Iv lost faith in the drop checker and bought others.
Iv done ph and kh tests to check it manually (highest result 7.5ppm)
Even when the bubbles per second were over 8 I wasn’t getting fizzy water out of the spray bar so confident the co2 isn’t just blowing out of the spray bar or causing air locks and escaping all at once unnoticed
Done lots and lots of reading online and nobody seems to have this problem so thought I’d ask the experts for some pointers or things I haven’t thought of.
Thanks in advance
Martyn
