the only driftwood is under all the java fern and the piece that the fissiden is attatched to. i thought about doing the whole driftwood amano thing but i like the wild natural look better.

Dorothy: Yes, I guess you're right.
First, take some distilled water, mix in a bit of baking soda, measure the KH, and adjust slowly until you get KH of 4 degrees, as close as you can get it. I used 4 times the normal water sample, so each drop of my AP test kit would equal 1/4 degree of KH. I think I got it to within +/-.1 degree of being exactly 4. Now, this water has no other substance that affects alkalinity and no substance that affects acidity in it, so it is "perfect" water for the KH/pH tables to give the CO2 ppm.
I had previously tested my AP pH kit to see if the number of drops of reagent was critical for measureing pH, and found that it isn't at all critical, just as I would expect. This means you can add more reagent to get a more intense color.
If you check the ph/KH charts, or better yet, the calculator, for KH of 4 degrees, Measuring CO2 levels in a Planted Tank, you see that the pH target to have 30 ppm of CO2 is 6.6. And, an error of .1 in pH gives a range of 25-40 ppm of CO2, which is a reasonable range, since you can actually see the difference between pH of 6.5 and 6.7, so you can easily reduce that error range if you wish, with a good careful look at the color.
Now look at the color chart for the AP or any similar test kit, you see that the color corresponding to a pH of 6.5 to 6.7 is green - slightly yellowish for 6.5 and slightly bluish for 6.7. So, it is easy to judge the color as being green, not blue green and not yellow green.
So, water with KH=4.0 will definitely be green at the pH that gives the correct ppm of CO2 for our tanks. And, if the color is yellowish, the pH will be low enough that the ppm will be much too high - about 70-80 ppm. Likewise, if the color is blueish, the ppm will be much too low - about 10 ppm.
So, if we put this KH = 4 water in the bulb of the "Drop Checker" with enough indicator solution to get a strong color, which took about 7 drops for me, we have not a pH indicator, but a good CO2 indicator.
its the ball looking thing next to the thermoter, really just for "whoa" factor since it takes some time to actually change in color.

Some new pictures of the tank, I kinda stunted the growth with an accidental Excel overdose so all the plants melted and are growing back out.
Planted some rotala colorata on the right side and have some Limno Aromatica, Ludwiga Acruata, and Ammania Gracilis coming from Aquadise. Only sucky part is he lives 5mins from me but have changed his policy to no pick ups and the package shipped out mid week but did not make it to me yet so it's probably waiting in transit over the weekend. Week in the mail to trave 5mins away.......
Also added 5 Koi Angelfish that I got from fishysue along with the one I had and my 3 dwarf puffers finally to the tank after the ammonia spike went away from the Aquasoil.
after realizing that human fingers dipping into tank means FOOD!!!
