Amano tank also have problem with green spot algae

[Shadow]

I was just browsing Practical Fish Keeping and saw this picture (refer to attached file). Apparently the tank also have problem with Green spot algae. Make me feel better

Check out the green spot algae on nana leaves

Green spot and green dust are always the issue in my tank until I reduced the lighting.

[hii]

as long as you expose nana to light (even low light) it will get green spot easily.

I was just surprise that ADA with unlimited supply of phyton gits still can have green spot algae . Even more surprise that it got published, they should photoshop it first . I guess python gits does not solve all the algae problem . I'm sure this is nothing to do with lack of nutrients or CO2 or water flow or lack maintenance, mistake that we often unconsciously have. I mean they are proffesional.

Hi Shadow,
What topic is the article all about?
From the picture posted, there is a word "Maintenance" on it.
Is it regarding tank maintenance?
If yes, I think the picture of Nana leaves with GSA is a good illustration of what happens if you neglect your tank or let imbalance creeps into your tank

[Shadow]

the full title is "Cryptocoryne and long-term maintenance in the Nature Aquarium". It was talking about plant selection for long term planted tank. It is not an example of neglected tank unfortunately

Every tank has algae. It is a matter of little or more. Active or non active. My tank has dormant BGA (beneath the substrate) and BBA (filter bars) but they are always ready to boom when the condition is right

[Shadow]

sure but I wasn't expected to be this obvious

Initially I was just trying to find a way to remove or reduce green spot algae on my iwagumi rock scape, without success. but then after seeing the photo on the article, I felt better. Even ADA have their share of problem with green spot algae and Amano doesn't seem to be care about it otherwise he wont sure the photo for his article.

I do not have GSA. We already know how to induce it. We got rid of this one about 2000 or a little prior when some folks really started adding more PO4.

At 2-3ppm, we have no GSA at all, this is a well known method to never deal with GSA. The only other issue is CO2, poor CO2 can easily lead to GSA. Most that do the ADA methods eye ball the CO2, they do not measure and look at it critically. Still, you can tell and add more if things are low for CO2.

PO4 dosing is een easier. Add K2HPO4. Done, no more on Crypts or Anubias.
This has been known for years BTW. Nothing "new"

You can also confirm this by inducing the Green spot algae.
I think Nerite snails, the zebras will gnaw on it as well.

I have not had GSA issues since the 1990's.

2-3ppm of P04, is that daily dosage or weekly dosage?

[Plantbrain]

A maintained residual. Generally 1.5-2ppm after a water changes and tend another 1ppm 2x, maybe 3-4ppm per week total.

You can also drain the tank to expose the leaves of the infected plants and make a strong solution of KH2PO4, and spray it on the leaves, wait 5 minute, then refill. Add 1 table spoon of KH2PO4 per 200mls.

The salts will kill the algae and not harm the plants.

But I generally trim off the infected leaves and wait for the new growth to fill in, yes, anubias grow slow, but not that slow.

They are not stem plants after all, so good long term care really shows. Lower light makes good long term care easier for mst, not that it directly prevents algae etc, rather, less light grows less algae and places less demand on plants for nutrients and CO2 particularly, which can induce algae as well.
I have high light tanks with Anubias, so do others as well without much issue.

Still, folks will have a high % of success using less light.

Try the higher dosing of PO4, make certain the CO2 is good, try the spray and see. You can also use H3PO4.
That worked as well for some folks.

Interesting idea, will try it out. Thanks

My issue is more on the rock, after awhile it start turning green. Normally I just use tooth brush to brush it off. After a while, I 'm wondering if there is better solution to prevent it.

what is phyton gits ?

[Shadow]

Aquatic plants are known for secreting phytoncide to protect themselves from diseases and germs.

Phyton Git is a formula which works gently with naturally extracted Phytoncide, as well as other disinfectant agents and helps aquatic plants to regain their natural strength.

Wow! This thread brought Tom Barr back!!! Well done

Anyway I saw that in the magazine too... a bit of carelessness I must say.

[uklau]

Great discussion !

Thanks, guys.

[Shadow]

Will double my current KH2PO4 dossage starting monday (12 Jan), and see whether it is improve within a week or two. Curently I dose 1.32 ppm 3 times a week.

[essabee]

So what is the feed-back ????

[Shadow]

I don't see much of different. Maybe it does in control environment. Accidentally 3 days black out is work amazingly well
