A couple of other things. You didn't say what fears you had, but I know when I first got started, I was literally afraid the whole thing could blow up or something. I don't think I really thought that, but I just felt intimidated by just not knowing anything about it.im already a little scared about a pressurized tank being under a glass tank holding 75 gallons of water !
Yes, there is such a thing as an end of tank dump (EOTD), but it's not as bad as it may seem. If it happened all the time, we'd all be killing our fish. It's a rare occurrence. There are a number of factors that contribute to an EOTD, such as it happening at night (most people don't run their CO2 at night) on tanks with tight fitting lids (most people have open top tanks), as well as a number of other factors.Ive also been reading about single stages "dumping, end of tank" why would this happen and why does it not happen in dual stages ?
That video does not show and EOTD. I'm talking about an event that takes place over the course of several days and you show me a video that lasts only a few seconds. It looks like someone simply disconnected the CO2 and bled out the pressure in that video. (The replaced working pressure gauge on his regulator also indicates he blew his original gauge by not knowing how to connect it properly; a common newbie mistake.)when a co2 tank is dry its 100% empty no gas, its befor its dry is where the issue can start when there is no more liquid left there starts to be a rise in output pressure hince rise and decay, there is NO dumping of gas. dumping of gas implys that it happends all at once which it does not it goes by the ammont that your allowing out to how fast you will see the rise in pressure.
with the rise in pressure with a low psi output the increase can go over 200% so if your near the limitations of what your fauna can handle is where people blame the increase of gas as a dump because they didnt pay attn to the rise in pressure, there are factors for how fast it shows tanksize, psi, usage etc etc so with a small tank with high output and low psi etc etc it might seem as it just dumped out but it follows a equation its not magic after all. here is a quick vid to show what im talking about u can see the rise and decay (rise in output decay in co2)http://www.youtube.com/watch?v=M08hPs-J3SM
id like to see what yours is doing it just seems out of the norm but it also depends on the regulator itself there not all build to the same specs. but the vid shows exactly what i was talking about rise/decay.
Yup, that was an EOTD. And you highlighted one of the many reasons why EOTDs are not always harmful to fauna: Even when the CO2 is "dumped" into the tank, it isn't all mixed in with the water. A good majority of it simply bubbles up to the surface and escapes the tank completely. Now if you had a tight lid over the tank, the small amount of air would then become saturated with CO2 so the oxygen/CO2 exchange at the water surface would have been effected because of the high level of CO2 in the air. But without a tight fitting lid, the CO2 just escapes into the room.After operating well for several months, my system also had what I would call an EOTD. It exposed my inexperience with this equipment.
I had not concerns with hooking it all together and that is what let me down. I had no gasket seal between the tank and reg connection but as I put it together, it sealed for no leaks at first. Last week, it failed and all the gas came out of a ten pound bottle. My first note was during the day and there was a terrific amount of CO2 bubbles going into my tank. I would call it dumping! The red tiger lotus leaves were lifting off the water. But I have a CO controller and when there was enough CO, it shut the flow down with the solenoid. Not recognizing what was happening I went on without checking the tank pressure. The next day the CO failed to come on and the tank was totally empty.
Having used equipment, I don't yet know what reg, solenoid or needle valve I have but I feel the combo with the controller saved my fish. But then since I do know that there are things to learn, I have less than $20-30 in fish in that tank.
The missing seal costs 98 cents and I will get several when I refill the tank. Unfortunately the gas will cost $11.50. Lesson learned!
Reactor:What's the benefit of having a reactor vs. a diffuser?
This is one of those things that you just have to experience. You might be fine with a hobby grade unit. Maybe you just want a better needle valve. Who knows. You can't really search about how you'll actually relate to a product until you use it and come to know its ins and outs.Asked, and answered.
Q: Is C02 really this baffling?
A: (14 arguments later) Yes. Yes it is.
I've been thinking of writing a post with basically the same focus as this one. But while the OP said he's been searching for 6 hours... I think I've been searching for 6 months. Really it's probably only been 2 months that I've been seriously planning on going pressurized, though my tank's been running on DIY C02 (on and off) for about 2+ years.
I greatly appreciate Complexity's initial response. It does seem to stray away from the OP's stated goal of not doing DIY stuff, just wanting to buy it and be done with it. This is my frustration, too. I'd like to just go to the pressurized-C02-for-planted-aquariums store and buy a complete setup without spending a fortune. There doesn't seem to be that store, though, and buying a complete setup somewhere seems to cost a fortune.
I think Complexity's first response really did nail something important, though: if I could just get SOMETHING started, I think I'd be a lot better equipped to make further decisions about what needs upgraded and what doesn't.
I've more or less decided I'm just going to order a regulator/solenoid/needle valve combo, maybe aquatek, maybe milwaukee, maybe one of those things GLA sells, a 5 or 10 pound C02 canister, some proper tubing and a diffuser. Trouble is every time I sit down to order it I started searching on here (and elsewhere) for information and see another of these arguments and another of those threads with the beautiful looking DIY dual-stage regulators and read about how Aquatek regulators are made of cardboard and tin and why the hell would anybody waste 100 bucks on that when you could build your own for 45 bucks using some fishing line and the spring from a ballpoint pen.
