bps too much?


So I have my planted 90g with pressurized co2, 3 48 inch T5HO bulbs raised 2.5 inches. I had an atomic inline but really didn't like it. I have my own version of cergis running right now off a power head. The CO2 seems to be completely dissolving. I am running at about 7 bps and there is no change in my drop checker. The plants look good. My only issue is that I have been battling bba. I will try increasing the bubble rate again tomorrow. Does this seem high or are these higher rates normal for "bigger" tanks. Honestly if it wasn't for the bba I would leave it as is but hope to correct the algae problem with the CO2.

I'd guess you're still far below the real limit. I had 3-4bps into a Rex for a 30g at 10 psi or so and was in the Mountain Dew range on my dc.

There's a good chance, depending on your pump and reactor size, that you'll run into the problem of CO2 not dissolving quickly enough before you hit the danger zone.

I vote for continuing to increase your flow rate

Or try adding another reactor. Which is what I did today.

another reactor in series or do you split the airline between two?
Also if I am seeing no micro bubbles will it make a difference?

Forget your bubble counter. Watch the color of the drop checker. Do this on your day off. What is your current working PSI? Try to increase it by 20% each 2 hour and watch the color of your drop checker. The color is should be somewhat yellowish by mid day, to deal with BBA issues. And fully yellow by the end of the light cycle. Watch your fish as you are doing this.

Try to run CO2 2-3 hours before the regular time .

Another reactor. Off another 2217. One for each side - it's a 6 foot tank.

So yeah. Splitting the line. My problem was getting the CO2 ramped up fast enough but then being too high by mid-day. (Almost gassed the Fire eel yesterday!)

Right now running 2-3 bps @ 19PSI into each reactor.

Didn't wanna jack your thread.. But your dispersion might be better with an additional way of introducing CO2. I had problems with my 90 too.

I am running a atomic co2 regulator V3, so I can't watch PSI. The only thing I can really monitor is bps. Also isn't yellow too much CO2? I thought we we are going for lime green?

You need to increase your c02. Start slow

have increased my flow rate a lot can't really count the bubbles too easily. Fish are doing fine. The drop checker goes from a dark blue to a light blue.
