Problems with Co2, need advice

[Huro]

I am having a problem with the co2 levels in my tank and I need some help quickly. The tank is a 55g, temp 77, pH 6.9, kh 8, gh 4, I have a gla complete co2 system with a pH controller. The issue is that according to my drop checker my tank isnt getting enough co2, I have replaced the indicator solution several times to be sure and left overnight and it is still blue. My plants which include hc Cuba are starting to fail, I am at a loss as how to proceed without causing my pH to fall. What am I doing wrong, please help

What are you running for lighting? How many bps?

Well then you simply need more co2. Can you increase it? How are you diffusing it?

I have a BML led 6700 for lights, I have bps set at 4 .......I use a atomic diffuser 75mm

That's odd, seems like everything is on the up and up.. could you possibly have a leak somewhere after the bubble counter? Does the diffuser look like it's producing the correct amount?

What is your PH before your Co2 kicks on for the day? Also, what PH level is the Controller set to shut off the system at? Lastly, what sort of surface agitation do you have on the tank(filters, bubblers, etc..)?

No leaks, the bubbles are consistent I do use bubble counter fluid instead of water. The controller is set to maintain a pH of 6.9. I do have the outflow of one of my canister filters pointed towards surface and it causes mild surface agitation. I will am not sure of pH without system running but will check and repost. Thanks BTW everyone

diffuser is fine BTW, I keep it cleaned with diffuser cleaner. The drop checker is on opposite side of tank from diffuser in case this matters and is gla pearl

UPDATE: Lights and co2 off for last hour and pH held at 7.0 also moved drop checker and now its in the green.

 

[Fishperson]

Sounds ok then. If you think its too low can you turn it up manually?

 

[Huro]

Yes, what ever I set the main system too will dictate how much co2 is released when the controller detects pH outside of the set range. Thanks again everyone for the help

I am pretty sure you are only supposed to use water in the bubble checker when using atomic diffuser Atomic+ CO2 Diffuser 70mm | Green Leaf Aquariums
look at 5 down on the important instructions part

Thanks for the info Thumper828, I clearly missed that.
