Hi All,
I am after a bit of help please. I have an issue where I have clearly done something wrong but I dont know what or how to fix it...
I have a 400L tank and since day 1 adequate co2 output has always been an issue, this week I have attempted to use the DIY method that @foxfish uses. Please see link here -
https://www.ukaps.org/forum/threads/high-flow-diy-reactor-now-with-video.23337/
The problem is, is that my setup is not diffusing the CO2 all the bubbles seem to be making there way back into the outlet pipe and forming in the spray bar as shown in the picture below
I am using one of the newer 10" water filter canisters as the old 12" ones are now impossible to find, the clearance at the bottom of the canister is about 4 and a half CM see below
Heres a couple of poor quality photos showing the canister setup
So heres some technical details
CO2 solenoid switches on 3 hours before lights come on in tank, releasing roughly 8 bps
My Filter is a Betta Choice 2000 UV filter which will turn around 2000L an hour, tank is 400L
At lights on my co2 drop checkers is still green it looks like it hasnt changed (fluid was replaced on Saturday)
so I am doubtfult any CO2 is dissolving in the tank.
I think my problem is one of the following
a) Clearance at the bottom of the canister is too large, majority of bubbles are pushed below this threshold and are escaping
b) The flow isnt strong enough into the canister and this is why the bubbles are not dissolving
c) co2 is coming out of the diffuser with too much force, being pushed straight down and then escaping before having chance to react with the water coming into the filter
But these are all just guesses, I dont know what I am doiung, more imprtantly I dont know what I am doing wrong.
Can anybody please help? please let me know if you would like any more info/pics etc
Thanks!
