did you turn the knob of the co2 tank atleast a few rounds? usually if you never turn it up the CO2 will just diffuse whats in the gauge.

Problem encountered to set CO2
Hi,
I'm experiencing some difficulty that I hope someone can enlighten..
I just set up CO2 injection. I'm using a manual pressure gauge (single gauge) connected to glass bubble counter connected to Power head driven co2 reactor which is placed inside tank.
After setting to abt 3bps, the bubbles in the counter will eventually slow down and stop.
Could the pressure in the reactor have built up to an equal level to the supply? But then again, after all co2 absorbed in the reactor, the bubble counter still does not resume..
HELP!

Advice from boss Felix
Hi diazman,
Thnx for the reply. Yupz I did, n I just chevk, it stopped again.. so I fullly turn it on this time!
I plugged out the air tube from the check valve n let it run (minimize resistance pressure) n still the counter went from 3bps to 1bps and slowing down..
Pressure gauge faulty?

It is normal to have unstable output since you are using manual regulator. You are trying to output couple of bubble per second from full 1000psi, very tough. Search around in this forum, you should see many similar situation with manual regulator.
Good Morning Shadow, Thnx for the reply.
So, whats the suggestion? Get dual stage gauge? But it only comes with solenoid..
Btw, how to link up pics that actually shows? thnx
i posted a tutorial here. you http://www.aquaticquotient.com/forum...045#post613045. you can ask me if you are confusedOriginally Posted by naz

Thnx Bro...
Still frustrated can't get stable CO2 output
Eventually you will get a hand of it very soon. Most people learn it this way. Keep on checking the BPS every half an hour until give up and simply go for a solenoid which comes with the bubble counter which is attached to the solenoid itself.
Aquascaper?
haha.. You're tight peanut8787
Apparently every hour or so, the bubble drops to a stand still. Estimated the CO2 contents derived from a chart using pH & kH and disappointingly it was low. The CO2 "meter" in that glass tube that's suppose to hang inside tank ain't accurate at all!
Any recommendations for a Reliable pressure regulator which does not burn a hole in the pocket? Whats the price? Or better still, anyone selling? (Do PM if inappropriate to post it)
Thnx
New solenoid regulator cost around $70 (taiwan brand) to $150 (german brand)
Thank you Shadow.
I was quoted $85 @ LFS in the north for a China Brand and i believe it does not come with a bubble counter as to what Peanut8787 mentioned. Any recommended place? So far I've only been to LFS @ Yishun and Nanyang Seaview for planted stuff. Heard of Nature Aquarium @ Thomson is very popular but I've not been there yet.
Any further tips to look out for? I feel kinda wasted to have purchased this manual pressure gauge.
dip your canister into water, check for valve leak.
dip your bubble counter in with all the lose tubing to check for leakage too.
I had the same problem, and my canister of co2 finish up within 2 weeks.
I've since learn.
Yes its normal to maintain bubble per second using normal valve.
I had problem too, when I try to set 2 bubbles per second, at the end of the day it will turn to become 1 bubble per second.
I've seen my plant pearling, not every time, but it did happen again recently, so I thought 1 bubble per second should be enough for me thus I give up on increasing more count.
I thought, if your plant is healthy then let it be.
If not, just look ahead and get one solenoid regulator without hesitation.
Price wise, I always believe those bigger stores will give you more discount :P (I might be wrong).
Thanks shunkun.
I don't think I'll be dipping my CO2 tank for leaks but I did initially found the tank head to be cold which did have a leak. At least you manage to set to 1bps. Mine came to a stand still!Every an hour or so it will just slows down coming to a stop. Perhaps I'll check again for leaks but this time I'll use soap water, kinda like looking for punctures in tyres.
Before I upgraded to CO2 injection, I was using CO2 doing from disposable canisters. I did a 50% water change, and saw my plants pearling while I was topping up water. No sure if it's because of the Light or because of the CO2 concentration level (as the water was lower, something about saturation of CO2) but it made my day!
no need to dip to check for leakage, just use soap bubble or saving cream in all the join.
Price might vary, My post was estimate price only and it does not come with bubble counter. I personally don't like the bubble counter that attached to the regulator because if the built in check valve fail, nothing will prevent water to go into your CO2 tank.
That's a good point shadow. Then how do you estimate how much bps?
What's the consequences if water were to enter? But I believe the output pressure will be enough to prevent it from entering.
you still put bubble counter but connected by CO2 hose with check valve in between.
The consequence is the factory will not or reject to top up your CO2 tank. CO2 + water is acid and corrode the CO2 tank.
I do hope that the pressure is strong enough to prevent it from happening but if you pay attention on your CO2 hose. The pressure is unable to push 100% of the back flow water out from the tube. Small amount of water will crawl down via the hose wall. So better be kiasu a bit
Another valuable information. Thanks Shadow.
yes naz,you manage to set to 1bps. Mine came to a stand still!
mine came to complete stop too, but not every after an hour but 1/2 daily.
it came out to be a leak at my one way valve. i change the tube, and again it happen, now its the other end of the tube. I've since changed both tubing. By the way, the tube was bought together with the co2 canister from seaview (can't imagine that will happen). I had to use my spare thick hard tubing i bought last time instead for previous D.I.Y co2.
hope it doesn't happen to you too.
