Gas'd my fish for the second time this morning...tips?


Hey all,

I woke up today to find my fish and shrimp at the to of the tank trying to get all the o2 they can. This is the second time I've had this issue in the past month and I was looking for some tips to avoid this in the future.

First time happened after adjusting the spray bar to try to increase the amount of co2 in the tank. The change meant minimal surface agitation which depleted the o2 overnight.

This time I'm not overly sure of the cause. I did remove some dead plant mass and did a 50% water change yesterday. As part of the removing I moved a few plants around and made room for some new plants that are arriving this week. I thought there was enough surface agitation but apparently not.

Paramters:
ph: 7
Ammonia: 0
Nitrites: 0
Nitrates: 10
Pressureized co2: 16ish ppm

Do you run your Co2 overnight?

This. We need this vital piece of information before formulating a diagnosis.

I do run co2 overnight. Was going to look into running an airstone on a timer overnight, but would looking into a solenoid a better idea? Any issues with ph fluctuation as it would only then run during the day.

If you're going to run CO2 overnight, I'd angle the spraybar for more surface agitation and just inject more CO2. CO2 is cheap, livestock lives aren't.

Just out of curiosity, what color is your drop checker reading?

A solenoid would be the better choice, since it would also help you save CO2 gas.

The changes in pH should be fine for your livestock.

Drop checker is green but it always seems to look the same green unless something drastic happens so I'm suspect of it. I figure out my co2 ppm using a ph/kh chart.

Get a solenoid. Why waste CO2 at night? Or get another timer and put an airstone on that during the night. That should degas the CO2 very quickly.

+1 for a solenoid. No point in pumping co2 into the tank at night when nobody uses it. Otherwise - an airstone or other surface agitation for now until you hook up a solenoid.

green drop checker and fish gasping for oxygen means low oxygen content. unless ur drop checker is 5-6 dkh.
id start by performing 2 50% water changes a week for the next month, and at least once a week a light gravel vac,
change ur mechanical filter media at least once per week, adjust spraybar so that it ripples the surface nicely, wasted co2 is much cheaper than dead fish.

bacteria in ur tank consume more oxygen than ur fish do. keeping the bioload down is the best way to keep higher oxygen levels.

Drop checker was done with tank water and drops as per the instructions I received so I am using a dkh of around 6. According to the chart it's been in the normal zone.

At this point I've ordered a solenoid (arrival in a week or so) and I've been manually shutting off the co2 at night.

I also noticed I'm having a flow restriction issue which I'm guessing caused the gassing (less surface movement so less exchange). I'm going to deal with that tonight hopefully but will run at less co2 for the time being until I get the solenoid and am around to make and observe changes (on vacation next week so away from the tank).

Instructions are wrong. You need a pure 4dkH solution. This is your problem.

There were 2 charts that I received. One if I used 4dkh, the other was for 5-8dkh. I've been going by the 5-8dkh chart as my dkh in the tank 6.

Does the problem still apply?

6 dkh and green checker
""((***MIGHT***))""
be ur problem, this could mean a high co2 content. green and 4dkh is not high

i'll still stick to my original theory that you have low oxygen content

run several airstones on a timer overnight.
