Response time to injected co2.

[Soilwork]

I set my new tank up about 3 and a half weeks ago. I left the plants in their for about two weeks withought co2 until I got it up and running.

Anyway the plants I had in their all began to show signs of co2 related issues. Stems dropping leaves, wilting etc.

It's been about a week and a half now and I noticed I am getting some algae and the and the edges of my Monte Carlo are slightly browning if you look hard enough.

I have a JBL e1501 running at full on an 85litre tank with my spraybar mounted along the back wall facing the front. Flow seems pretty good.

I don't have a drop checker yet but my ph is dropping to 5.9 which was what it was dropping to when I had my 180 litre and there were no problems with that tank.

My KH reads 3 using the API test kit.

My real question is, do you find that you have to go through the motions of older growth being attached with algae whilst waiting for the plants to put out their newer leaves what have been constructed to reflect the new higher co2 concerntration?

My S.repens is the most afflicted but the majority of leaves under the newest growth are the original leave. Would you expect the plant to discard these leaves? Is s.repens known to be a slow grower?

The Monte Carlo is carpeting but I can't tell if the browner growth is the older stuff.

Any thoughts?

Yes, Staurogyne repens is usually a slow-ish grower.
- and yes, the leaves not capable of adapting to a new environment (=going submerse or changed CO2 ) will tend to be attacked by algae.

Where possible; remove affected leaves.
Where this is not an obtion; wait patiently for enough new, adapted (=healthy looking) growth to cut from the plant. Then discharge the affected part and re-plant the off-cut, adapted parts.

Cheers Mick. I figured this would be the answer. I do have just enough growth so will give that a go.

How is your dosing scheme?? I got submersed staurogyne repens in my new tank and only start dosing after about two weeks old(half old soil half new soil)
Before dosing even with co2 they (and other plants) also got algae on older leaves, and new leaves appear smaller. Then I start dosing kno3 and comprehensive and everything just grow faster and bigger.

As you can see there is no algae accept some Diatom on old leaves which is normal for new tank

Thanks for the reply and sorry for the late response. I have been toying with the idea of a micro toxicity after reading various forums on the subject. I'm still suffering with browning leaves. My plants are pearling and I now have a drop checker that is green when lights come on.

I stopped dosing micros because of the toxicity hypothesis. The lower leaves of the S repens when almost white with th odd green/yellow patch. Since stopping the micros the S repens began putting out healthier leaves but they are still brown just on the edges just like the Monte Carlo. It's still an issue. I halved my EI for macros because of the toxicity business so maybe that is causing issues too? I haven't tested for phosphates or nitrates for a while so they could be low. I don't know how fast they are taken up. I never had a nutrient deficiency when I had a soil substrate but now I have switched to eco complete.

I'm running a Chihiros A series on full power 60cm length and the standard depth of an 85 litre tank. Not sure what that is at the moment. I've only just switched the light to max the last couple of days. I thought maybe the carpet need more. Maybe it needs more still? I have a cover on that is refracting a lot of light due to water droplets. Things haven't gotten any worse with the light at max which makes me think this is nutrient related.
