Small bubblescoming out of reactor

[taz_boy]

hi,

i found that there are tiny bubbles coming out from the exit of my internal reactor.....
does that means that the CO2 is not fully dissolved??
my reactor i did something to it...used to have an atomiser, but removed it cos always clogs up, think it's algae....so rite now it;s connected to my powerhead....with 1 bioball inside....

can i add filter wool into the reactor....cos that's wat pple suggest when doing DIY reactor....will it aid in the dissolving rate??

Yup, not fully dissolved.

Thats O2 degassing during the photoperiod. You can try drilling a small hole about 2" from the top at the side of the reactor tube and add a air-line to it back to the intake of the powerhead for venturi action. Remove the bottom cover of the reactor as well as the bioball. Note that the powerhead intake must be in an orientation such that the excess CO2 can burp out when the reactor is off or else it will airlock.

hmmm.....peter...quite chim leh......dun really get wat u suggesting to me

I'll get Tom Barr to post his DIY internal reactor here with diagrams and pictures which will help your imagination.

Yes it does mean that the volume of CO2 that you are injecting is not being completely dissolved, this might be because the Bubbles Per Second [BPS] setting that you are using is beyond the absorptive limits of the water flowing through it and the internal reactors ability.

This might not be a bad thing as you know that for your setup that you are at the maximum.

ok.....think i'm having like ph 6.6-6.8 now, kh 3.....so it's around 24ppm...
so i wonder will adding filter wool into the reactor helps in the dissolving, since the co2 gas gets mixed longer before it exits
