Uhm, isn't it the other way around? They go up to the surface regardless, I'm guessing lower O2 will make them go up even more. If they're breathing heavy, and not active than I'm sure it's a sign of low O2.

That's what I thought too.

I don't think it's possible for my system to gas my fish. I use a pump to blow water down through a gravel vac tube while the air hose bubbles into it. I put a filter into the bottom to prevent any bubbles from escaping. If I crank the co2 the amount in the water doesn't change, it just displaces the water in the tube more and eventually just bubbles out. It's a very efficient system and was cheap for me to setup and I don't have to worry about gassing my fish.

This is on a 125 with a ton of plants however so in a smaller tank or with less plants it might not be as foolproof, but it works for me.

Well, I sure hope so. But that statement will never come in my mine after this incident. Anything is possible. Nothing is bulletproof.

Well I had a nephew turn the knob up where gas way pouring into my diffuser setup and I didn't notice until that night and fish were fine. So hopefully I'll be safe but that doesn't mean I don't keep a better eye on it now.

It is amazing how little CO2 it takes for your fish to get gassed. I haven't gassed my fish yet but in one of my tanks I have two large HOB's and I can crank up the co2 with a reactor to three or four bps and the fish aren't even phased. However in my other tank, there is almost zero surface agitation AND there's a glass canopy over it. It's around the same size as my other tank and I was putting in less than 1 bps and when it got to 6 or 7 pm the fish were already gasping for air and their gills were fluttering like crazy. Luckily I caught it in time and put in a bubbler. I don't even use CO2 in that tank anymore and my plants survive almost perfectly with the CO2 that builds up from the fish.

Yeah good point, I run mine open top so that could be a contributing factor as well

I feel your pain. I lost 80% of my tank about a year ago. By the time I realized the problem I only had 20% of my tank left. I was using the Milwaukee co2 regulator with bubble counter and my co2 tank dumped. I now use the Aquarium Plants.com electronic regulator. Impossible to dump now and alot more effective. A bit pricey but well worth it.

Agreed. It doesn't take too long for the fish to gass out. I usually have the CO2 running without surface agitation, then when the CO2 is off, I have the surface agitation.

Thanks. At least you got 20% left, but still it's sad when you saw them died. In my case, I would not blame it on the reg. I would say it's my own fault.

Very sorry to read of your loss...

Next time around with C02, possibly think of using a two way PH controller like the American Marine model if your budget allows.

I have been using one for years and always keep an air pump plugged into the low side with an air stone connected in a corner beneath the substrate that I place at setup. Twice over the 8 yrs or so of using the controller, I have had solenoids stick open and the air pump will kick on once it goes below the low PH setpoint I have programed and offset the constant gas being pumped in long enough for me to notice and address the problem.

Yes the airstone will muddy the tank and disturb all my substrate and plants in that area, but much better than the other outcome.

I think alot of us have done this. My incident happened over the course of a week slowly killing off half my tank. Then I realized my sub par regulator dumped the remains of my low co2 tank. It happens to the best of us. That's how we learn from our mistakes.

I am truly sorry to hear this. Let me share a little unrelated, yet somewhat related story: I grow carnivorous pitcher plants and it took years for me to gather some very rare and expensive plants. These plants require cool night temps and as a student, there is only so much I can afford, so I used to use outside winter air to cool my plant tank down. The plants were growing amazing and I grew them from 1cm size. I grew seedlings that took 3-4 years to grow from 1cm to 2". But in one night, during January this year, I lost over 40 of my most beloved plants. Heck, I got into aquariums now as a way to distract myself over that loss. However, I still try to tag on with it and keep the survivors chugging along. It was a major blow and i lost almost a thousand dollars worth of plants. More than the money, it was the care and effort and the love I had for them.

Bottom-line, [censored][censored][censored][censored] happens and we got to live with it and move on. It sucks, but the best we can do is keep this incident in mind and learn from the mistakes. Have failsafes next time. Maybe have some sort of mechanisms by which u can ensure adequate air intake into the tank. It may mean your plants have to grow slower due to in-efficient CO2 absorption, but its better than killing the inhabitants.

Unhappy Dude! Wow! Oh Man!

Dude! Wow! Oh Man! At present, I run my CO2 on my 65-Gallon on the light side (rather too little than too much... plus I hate to trim all the time). I have a Victor (2-Stage) regulator. At present, I run CO2 overnight without an issue and have great plant growth. Again, I err on the light side when it comes to CO2 (always!). I had a solenoid though was not happen with it at all so I no longer use and I decided to save a little money and purchase a CarbonDoser Electronic Co2 Regulator (super precise bubble counter). Several members of our aquatic plant association use them with great success. Since the units are electric, they can double as a solenoid and do work with pH monitors/controllers. Once installed, I will save some CO2 and sequence it with the lights on timer.

In closing, I am really sorry to hear about your loss... that sucks beyond what words can convey. I am glad, however, to see your continue on... my advice besides saving for good equipment (name-brand, two-stage regulator, possible carbondoser, and maybe down the road a pH regulator.... do what seems so obvious now... err on the light-side when it comes to CO2. Oh, and rather than link tanks, I'd focus on the large one and use the above set-up for that... you might run a side-line to smaller one with a regular bubble counter and simple valve system down the road.

Anyway, I wish you the best...

Nifty, but what happens if you lose power for an extended time ?


Recently my regulator I've been using for over 25 years has failed. It had a solenoid valve. Now I have a new one. This unit is very simple. It consists of a needle valve and regulator.

In the beginning of the month (April), I wanted to rescape my 50G tank (here is the journal: http://www.plantedtank.net/forums/ta...han-green.html). Even though the tank has been great since last year, I wanted something different.

Before:


After:



It was fun (getting all the stuff clean up). I was pretty happy with the new look. Then I started to adjust CO2. Also I am using the splitter to distribute 50G and 10G tanks. After a few days, I realized that I needed to do more tweaking as the CO2 wasn't coming up enough. After fixing it, I woke up in the morning, and I saw the CO2 didn't turned off. However, I didn't see any issue with my fish. They were still happy and looked healthy. Well, more tweaking needed obviously.

At this point, I am still trying to find out what's actually happened. I was basically trying to get all working together (timer, splitter, cylinder valve, regulators). Somewhere along the line, I made a huge mistake. I left the tanks for less than 3 hours, and when I got home, this is what I found:










I was shocked, sad, angry, pissed off, etc. It was a disaster. I tried to rescue some, but they didn't survive.

As I told you earlier, this CO2 was connected to another 10G tank. I lost all of my fish there as well. What's even more sad news, I was loosing a battle with brown algae on that tank.

Before:


After a month:


So yeah, it was painful. As far as the fish casualties from both tanks, I lost all these:

Neon Tetras (x 40)
ForkedTail Rainbow (x 4)
SAE (x 6)
Corry (x 4)
Bumble bee Gobi (x 2)
Pseudomugil gertrudae (x 4)
Rummy Nose (x6)
CPD (x 6)
Scarlet Badis (x 6)
Otto (x6)

RIP


So yeah, I was considering to drop out of this hobby. But guess what, if it doesn't kill you, it makes you stronger. I will comeback even better and I have learned hard way. I thought that CO2 disasters would never happen to me. Yes, it could happen to anyone. I just hope that this might be an eye opening for fellow hobbyist, since I do not want this to happen to anyone. Be careful on CO2.

LIFE GOES ON,
Dotto ditto I just lost all of my rainbows, neons, green cats, pleco, several others. Solenoid malfunctioned as I had it turned completely off. I am so shocked and sad. I am going to wait till CO2 is disipated with lots of aeration and re intro later. Wpw it was only 3 hrs I left the tank.
