What's Your Fish Load in Your Planted Tank?

I know I am way overstocked, but I have a 10g, heavily planted, no co2, with 30+ guppies. I use Excel rather than co2. At most, I lose maybe 1 or 2 adult guppies per month (that I see)

Interesting. So I assume then your thinking some fish are more sensative to co2/o2 levels and trying to see who else is running what fish in thier co2 injected tanks. I can tell you that some fish are sensative to high co2 levels, though I dont have a comprehensive list or anything (as well as most fish obviously sensative to low o2). But... I find it hard to beleive the levels would significantly change in a matter of minutes. In my tank I have a strong enough filtration that I get ripples in the surface, along with an extra powerhead at the surface at night... and I dont see a significant drop in co2 levels for those 14 hrs the co2 is off.
I'd suspect they were probably just noticing the change in flow in the tank or perhaps a stronger current? Was the water any cooler coming from the sump? I have a big circulation pump in my tank (Koralia 4) and when I first turned it on I noticed a huge change in behavior of several fish in my tank. Just an idea for an alternate reason for ya.

The sensitivity level vs. co2/o2 level is what I'm looking at.

The pump I turned on is rated at 1320 gph, so yes there was a significant change in o2 level as the water was getting churned up quite a bit coming through the overflow. The output is 1" pvc too. LOL.

OT: Made me impatient to set up my Hillstream loach tank.

I'm doubting that I could run that and still maintain any amount of co2 in the tank. I would think that it would degas faster than the plants could utilize it.

What temp is your planted tank at?
 
I definitely tend to stock on the heavy side in most of my tanks, but I choose my stock carefully and it works for me. I have 2 heavily planted tanks.
55 gallon, 130W PC light, no CO2:
3 discus
2 apistogramma steindachneri
5 rummynose tetras
4 green fire tetras (used to be more, but I've had them forever and some have died)
1 tiger pleco

45 gallon, twin tube NO flourescent, no CO2
2 pearl gouramis
2 female bettas
1 keyhole
5 gold pristella tetras
6 harlequin rasboras
3 yo yo loaches
1 clown pleco
 
I know I don't have to say this, but the more plants you have, and the more they do their photo thing, the more oxygen they will produce for the tank.

I honestly don't think you are seeing an issue with oxygen depletion however, as you know adding CO2 does not displace O2. I would have to guess that your fish perked up because of the increased current, not the increase in O2. I'm assuming the fish weren't gasping at the surface prior to you turning on the pump, correct?

Also, if you aren't creating tons of bubbles and turbulence at the surface with your pump, you may be able to successfully run CO2 at the same time. Only one way to find out for sure.
 
75 gallon CO2 and controller. DIY inline diffuser. 1 betta, 3 swordtale, 4 platties, 15 harlequin rasboras, 6 corys, 2 SAE, 3lemon tetras (for some reason they do not make it my tank), and if they are still around...2 kuhlis (sometimes I forget and they show up after 2 years...lol) . Maybe more, but that is all remember.
 
I haven't ever really been a fan of fish in my planted tanks. I have 6 amanos, and a 3 different types of snails though in my 10 gallon. I think I may add another type of shrimp at some point in the future, probably red cherries. I've never had amanos before, and I'm really pleased with their cleaning abilities thus far.
 
I have fish in all my planted tanks. The key is to find a balance on surface agitation, Co2 Injected, and enough plants to produce o2.

Even with surface agitation injecting Co2 still helps. You jsut can't go from one extreme to another and say look Co2 is bad for fish.
