Question EEEEK!! My God. Thankfully no fish in there yet!!

Ok, it's a newly planted 10 gal (as of Saturday) with two 10w mini flourescent bulbs, fluorite substrate with peat moss beneath. Since Saturday the plants (all but one) look healthy enough - though dustry from settling of fourite.

Today I added a DIY C02. I checked my pH (usually high - about 7.4 in my other UNPLANTED fresh water tank) and the newly planted one is now 6.2

Using the new kH test, it took 10 drops to turn the solution in the test-tube blue - meaning 100 ppm

Using Chuck's handy dandy Co2 online calculator I seem to come up with a figure of 106.0 ppm for my C02.

What have I done wrong? I believe it's supposed to be about 10-25 ppm?

No, you don't have >100ppm CO2. Peat acidifies water and you get false Co2 estimate. Fish would be fine.

Thank you. I had wondered what on earth I had done wrong. So how then do I determine if I have the right rate of C02? Is there such thing as too much? And with the new lowered pH, does that mean my fish will hate their new climate when they're accustomed to 7.4??

you can't estimate CO2 accurately with peat affecting ph, have to go by "feel'. If the plants don't do as well as expected for high CO2, turn up Co2 a little more. Your fish can't care less about these ph difference, within reason.

OK, excuse my lack of knowledge, but, it's a DIY C02. How do you turn it up?

You cannot turn up a diy co2 bottle. It has prety much autonomous control over itself. What you can control is how well it difuses into the water or you can get of it and get a pressurized system.

DUH, didn't think so but this newbe had to ask.

Its been a few hours so I redid the chemical tests. Results:

Ammonia = 0.5
N03 = 5ppm.
kH = 90 ppm
pH = 6.2
C02 = 94.6

New planted tank, new DIY C02 which is now bubbling like mad. No fish in there just yet - they're on stand-by in the spare 10 gal. just raring to go.

I added one tetra earlier tonight and he gasped and kept to the top of the tank so I plucked him back out and returned him to the other tank - afraid the water was out and I was torturing him or something.

The C02 is high because of the use of peat moss below the fluorite substrate, that understand.

(1) Are there other measurements that would be helpful?
(2) Am I just a worry wart about the fish and ought to toss some in?
(3) Are the rest of the chemicals ok?

you probably should wait awile until the ammonia goes down, that is super deadly to fish and then you should probably slowly acclimate the fish to the tank enstead of just dropping them in.

The CO2 is NOT high because of the peat. It only SEEMS high because of the peat.
