Hey this is not the typical question about how the KH
/PH relationship works as I kinda understand that.
Here's the thing, my plants are not doing that great and I'm having some algae. Now I think the algae got kick started by ammonia, and prob low nitrates.
Now my PH in my tap water is ~7.5 best I can tell from both high and low range PH test. And after sitting out the PH is 8.0. Now I had talked about this before and someone told me the reason this happens is that there is likely CO2
in the water in the pipes and it off gasses.
I have a GH
test kit but for the life of me cannot locate it. I tested once right when I got it and both GH
were ~20 IIRC and if I did it correct(the 1st drop counts also correct?)
I know that CO2
fluctuations can occur from tap water from what I've read and there is info that says lower tech/non CO2
injected tanks may be better to not do as many water changes due to this.
Measuring CO2 levels in a Planted Tank
Now the reason I'm asking is because my plants seem OK some days I thought and other days look bad(like I'm going crazy). Now Like I said I'm getting algae.
Last couple days notes: 55G tank(lets talk about Rotala rotundifolia mainly)
8/22: plants not looking great, rotala leaning sideways, so after lights out, cleaned algae that I could get off driftwood and did a WC
, think it was 10G
8/23: Algae coming back, rotala leaning, see small new growths on it, like new plants shooting up, while the main plant leans.
8/25: Cleaned algae, Did a 12G WC
4hrs before lights come on to give time to off gass(I thought). At the end of light period Rotala sticking straight up and pink on ends more then ever before and pearling more than ever. I was amazed at how much changed in 8hrs of lighting and a 24hr blackout the day before. No algae pearling on driftwood, thinking I have got it going.
8/26: Plants not looking great, rotala sideways again after lighting and algae started appearing on driftwood again, it is pearling so I see lots of bubbles on the wood then if left for a couple days it will be covered.
Looking at the charts for PH/KH
, it seems that assuming my KH
is the same in the tank than I should have ~4ppm CO2
Is is possible for me to have 10ppm(or more) of CO2
in the water straight from my tap??
Also if I do a water change I have crazy bubbles all over even with lights out and after hours. SO is this whats going on or am I crazy?
I also know that phosphates can throw off the KH
/PH chart for CO2
, I ordered a test kit for this so hopefully that will shed more light.
Just had to vent
