Amazon Sword is trying to tell me something!

What is my Sword trying to tell me? What do I need? I know there's a story there! Don't be gentile!

Ferts: 4 pumps of Easy Green once a week, 2 Seachem fert tabs under the Sword once a month.

CO2 Injected - pH @ 6.6 during the day - air pump at night with the pH going to 7.0 at night. KH4, GH 6-8, NO2 0, NO3 - Don't ask. However I've been doing 5 or 10 gallon water changes every few days since last month.

Its most likely the high nitrates. If this tank has NO3 that high just from fish load, I would maybe find a different fertilizer than Easy Green which is just adding more nitrates with each pump. For my high nitrate tanks I use a micro solution and for macros I just use KH2PO4 so I'm not adding more NO3.

Hi @ZuppaDePesce

I downloaded and enlarged your full tank picture; is it fairly recent? If so it may give us a clue. Here is what the plant on the right rear looked like....does it have the dark leaf veins and substantially lighter areas between the veins as we see in the picture?

Since you didn't mention, how often do you trim leaves? Swords do benefit from being trimmed.

I too had to ditch all-in-one ferts so I could back off on introducing nitrates. Modified macros with slightly more micro's. But that's just my tank.

That's so cool you did that! These pictures were taken today for the purpose of posting here. What you're pointing to is just a strong reflection of the light off of a Java Fern leaf. I took another, closer shot of that same area. You can see the leaf better (It's pearling). HOWEVER, you made me notice a newer Sword leaf (left of center) where the veins are lighter than the rest.
@pauld738: I prune as needed, which is as least once a month . . . I need to cull the Java Ferns! I just don't know what do do with them. I hate throwing them out! . . . . I really don't want to ditch all in one ferts! I'd rather under use it and supplement. But I don't know what I need!

I'm convincing myself that I've been lazy about the water changes!

1) I just finished a 5 gallon water change. I plan on doing another on Sunday. I'll keep up with the frequent water changes until the new test kit tells me levels are acceptable. Then I'll study my tank until I discover what the water change frequency needs to be, and how much. (I hope 5 gallons at a time eventually works!)

2) I ordered a new Seachem Nitrite/Nitrate test kit. I was not shaking the #2 bottle of the API Nitrate kit for the first 6 months of using it, so I cannot trust the results! It shows my tap-water has 20ppm Nitrate! According to my local Water Authority the High reading of Nitrate last year was less than 9ppm.

3) I added an extra Fluval C3 with Matrix media. I still was able to use the filter pad in the back, but all 250ml of the Matrix took up both the charcoal and bio-media chambers, but that's fine.

Hi @ZuppaDePesce,

Based upon the interveinal leaf puckering (puckering of the areas between the leaf veins) in the most recent photo and the marginal (and tip) leaf scorching in the first picture I suspect that the issue is insufficient available iron. Sometimes the issue can be caused by dosing the wrong type of iron (ETDA, DTPA, ferrous gluconate) for the pH of the tank but I don't think that is the issue with your tank. Easy Green is a 'low iron' fertilizer and interveinal chlorosis is not an uncommon issue, especially in higher tech tanks. Pick up a bottle of Seachem Iron and dose it per the instructions on the bottle for 3 - 4 weeks. Watch the new leaves as they emerge, do not watch the existing leaves....they will not change. Does the color of the new leaves look better? Do they look healthier? Watch these new leaves as they mature, they should not show the interveinal leaf puckering nor the scorched leaf margins. Let us know how thing are going as they progress.

B. Terminal bud remaining alive. Symptoms on new growth.

1. Interveinal chlorosis on young leaves.

a. Interveinal chlorosis on young leaves with larger veins only remaining green. Necrotic spots usually absent; however, with extreme deficiencies, young leaves are almost white and may have necrotic margins and tips; necrotic spots may extend inward. potassium, zinc or copper excess can inhibit uptake of iron. High pH may also induce iron deficiency....iron deficiency

Iron deficiency symptoms are similar to those of magnesium deficiency, but iron deficiencies occur in young leaves first: Iron accumulated in older leaves is relatively immobile in the phloem.

@Seattle_Aquarist knows his stuff. Follow his advice.

I was thinking about your use of root tabs. In my experience they do a great job with Java ferns. I'm wondering if your not using enough? You have alot of plant there so maybe it worked in the beginning but now not so much?
Not saying you don't get the seachem iron as your running co2 and my experience with tabs and ferns is without co2. But it may explain why it started happening.

In that photo above, the leaves that look puckered are Java Fern. The ones coming in from the left are the sword leaves. Regardless, thank you so much! I will do as you describe.
@pauld738: I only use the root tabs in proximity to the Hygrophila, Aponogeton, and Swords. I'm under the impression that Java Ferns are water column feeders, no?

Sorry, I meant the Swords!!

Don't know how I mixed that up.

And I'm answering a week late, lol!

@Seattle_Aquarist: It's very cool of you to ask!
I think the main issue I need to deal with right now is high nitrates. As a newcomer to this level of aquarium keeping (in my second year), I feel like a lot has gone unnoticed and my good/bad habits are revealing themselves.

As I've stepped-up the frequency of my water changes, I've observed faster plant growth and increased pearling. Especially the Aponogeton Boivinianus! Even the fish are more active and less shy. I've added Flourish Iron to my weekly fert routine of Easy Green (and montly-ish Seachem root tabs). Some pesky emerging algae spots have gone away too.

I've added a second HOB filter with only Matrix media in it (full small bottle worth with a filter pad in front of it) and plan to add Aquavitro Seed when it arrives.

That's it for now.
