Great! A week ago for the initial setup of one of my newly bought planted tank, I tweaked it to 2 bps. I dropped it down to 1 bps due to having too high of a lighting and the co2 causes a massive green water outbreak. Doing water changes daily to get rid of it. On the other hand, plenty of plant growth. I expect to have a Glosso fully cover mat in 3-4 weeks.
Just wanted to pop in and say thanks for the setup.
I decided to take a test run using last night using a "chopstick diffuser" method last night, and placed the diffuser into my HOB where it's sitting underneath the impeller motor...made myself a little DIY reactor back there. Drop checker went from blue to green over night, and it's been green all day. Decided to turn the flow rate down since it hasn't shifted toward a darker green all day, and I'd like to try leaving it on 24/7 and know that I won't gas my tank...we'll see how that goes.
I've actually had zero issues getting a steady low flow rate. Right now I'm sitting at 1 bubble every 5 seconds. Last night it was 1 bubble every 3 seconds, and was still right there when I got home. I decided to turn it down a bit tonight, just in case. I figured I'd play it safe since the drop checker started out blue last night, and it's starting out green tonight...
Made myself a DIY bubble counter using a BD Vacutainer urine collection cup, lol. Had PLENTY sitting around at work, and the design made it a no brainer for making a bubble counter. Here's what they look like:
So...thanks again, I'll keep you posted. Definitely stoked about the upcoming rescape and the explosion of growth that I'm sure will go along with it.
I should also mention...I did attempt to use a standard glass diffuser, and noticed that the valve and the outgoing pressure had to be significantly higher for the diffuser to function properly. Also, the bps rate seemed to fluctuate here and there with that setup. Not sure why...just an observation. Perhaps I was impatient though and didn't give things enough time to settle in since I only had it going for an hour like that. But, in the end...I decided that I didn't like the mist of bubbles sitting on the top glass of my tank (fluval edge), so I decided that I'd stick with the HOB "reactor" and see where that takes things.
Total cost for pressurized CO2 (minus the diffuser that I'll probably sell off): $54 :b
Ok, I just got off the phone with my vendor that supplies me with PB parts.
I showed him this setup I have.
He said that works great. The only thing he would do is to remove that 2nd gauge and use a more precise (often time bigger) gauge with readings from 1-10 psi increments.
He also mentioned, that a regulator is not needed in this application because a regulator is used to control constant flow of VERY HIGH OUTPUT PRESSURE.
He gave me an example.
850 psi + escape from the PB tank, then is held back by my Needle Valve. Until that Needle Valve is opened, a set psi isn't marked down. A regulator would be needed, if you are outputting alot of psi. Alot to him is 100 psi. (He mentioned 100psi as the example). So if 100 psi comes out of your Needle Valve from the 850 psi that is stuck in the ASA On/Off Valve chamber, A regulator is needed to regulate the VERY HIGH PRESSURE Flow.
His comments regarding all my setups is that, it doesn't need a regulator at all. He also mentioned with the setup I have, fine tuning is already accomplished. The pressure is held back as long as your Needle Valve can take it. This is why you're able to go down to 1bps being lowest.
I'm not sure if that answers some of your folk's questions regarding a regulator. But to me it seems very right. Constant flow is already given at such low bps for our applications that its used in. I still don't see a need for a regulator.
Let me know how you folks think about it. Or have any questions I can ask him.
Just so people know, regulators aren't cheap. If one feels more "happier" with a regulator, I assume you'll dish out $30 + dollar for one to be hooked up to this PB setup?
