First Planted Tank hand holding required...!

[smithrc]

Just had a look back through some of my old posts to find this...

Dose it work?

My local plant 'specialist' gave me a good guide that has come good...
Volume of water (in Litres) x KH (in degrees) / 50
so our 200L with a KH of 9 = 36 bubbles per minuite.
Now that we have near 100% desolving we have a PH of 7.0 and a co2 content of about 28mg

Dinos tank (125 * 5.5) / 50 = 13.75 bubbles per minuite.

doesn't sound like it does - Are the bubble gone by the time they get to the top of the ladder?

I suppose a higher % dissolved helps.

Sorry gf! I wasn't nit-picking, honest!

I just thought I'd mention it before someone asked, how do you count the bubbles when they're travelling that fast?

Am i doing this correct

My tank is 160 litres

Kh is 1.7 degrees or 30mg/l

so 160 x 1.7 = 272 / 50 = 5.44 bubbles per minute

Now im useing 2 ladders and i would guess without auctually counting that im getting (well auctually curiosity got the better of me and i did count)

1 ladder is produceing a bubble every 5 seconds so for 1 minute thats 12 bubbles the other ladder is produceing a bubble every 8 seconds and for 1 minute that is 7.5 bubbles and this gives me 32ppm of co2, my Ph is 6.2.

Anyway interesting if it did work, maybe im doing it wrong.

not quite, I would say they are about a 10th of the size they were when they start at the bottom.

I thought after the change to gf's CO2 recipe yesterday in one of my cannisters, I would check to see if it had made any difference.

My reading tonight:

pH - 7.0
KH - 7.2
CO2 - 22ppm

I think if I change the mixture in the second cannister I will hit the magic 30ppm!

Something does strike me as strange though...KH value:

24.07.05 KH 100
27.07.05 KH 120 *
28.07.05 KH 130

(* I expected the hardness to remain constant and presumed I had mis-counted so used 100 in my calculations)

is this expected?

My KH always remains constant if that's any help.

 

[nodding_dino]

thanks George, thats' what I would have expected too...I'll keep a close eye on things over the next couple of days...I'd be happier knowing that everything was stable before starting the Ei project!

my kH fluctuates between 5 and 6ppm

due to water changes?

 

[zig]

My Kh never changes, always dismally low at 1.7

 

[nodding_dino]

cheers guys...I'll keep you posted!

oh, didn't think of that. maybe. I'll look at my notes (been keeping a record of test for a couple of months now).

 

[nodding_dino]

well, tonights test showed hardness at the same level as yesterday...130 (7.2) although pH seemed to be too green for 7.0 and to blue for 6.8 - I'm going to make a stab in the dark here and say pH is 6.9 this puts CO2 at 27ppm...the magic 30 gets ever closer!!!

 

[George Farmer]

CO2 at 27ppm...the magic 30 gets ever closer!!!

I wouldn't worry too much about the extra 3ppm. Kits aren't reliable enough for you to know that's a true level anyway, as long as you're in the ballpark and it remains fairly stable (30 +-5ppm) then all is well.

BTW it's great to see you've gotten into the hobby so deeply and quickly - I look forward to seeing the results.

Zig im in the same boat as you my kh test changes colour first drop so i add bicarb in my water changes- 10 ml per weekly water change (50L for me) gives me 143.2 ppm or 8dkh
