I wouldn't worry about the Sagittaria. It could be allelopathy. That's why I recommend planting plenty of species. Let the plants fight it out.

Good recovery. Good job!

Five months update.

Well well well, almost no traces of BGA. And a couple of questions.

Do you think is trimming and replant time?

About poking substrate and doing water changes, I am doing once a week 30% WC and a little poking. Do you have any advice for how long it's convenient keep it doing?

And the last one is about life stock, I do have one ramirezi, one guppie, one little (I do not know what family is) and two ottos. And a couple of snails.

Ok,. I think now tank is doing fine. So I will wait for your kindly advise.

Thanks Diana, Hoppy, mysiak, and all who participate in my tank.

Yours, Leonardo!

Your tank looks great! I would just sit back and enjoy it. The plants are now growing well enough that poking and water changes are not necessary. With your help, the plants have gotten through the temporary problems of a new setup. Nice work!

Hello everybody, it's been an eighth and a half month since I setted up this tank.

About the algae, I still having some spots in the acrylic, but is under control, and in fact I think it is part of the natural cycle and while it does not disturb the plants, for me it's ok.

Regarding the grow of the algae I have several possible theories I would like to discuss such as

1) Insufficiency of CO2
2) Lighting problem.
3) Combination of 1 and 2

Regarding CO2 Insufficiency:
So mi first hypothesis is based on the Red Lotus. I think these plant led to an insufficiency of Co2 due to the excessively consumption leaving the other plants of the ecosystem with no CO2 to photosynthesize.

Regarding lighting problem.
Here I have more doubts than clues.
First of all, I have an issue with the location of mi PLL tube it's more in the front than in the middle of the tank. So almost all plants grow turning from middle and back to the front. I'm wondering if putting two PLL, with less individual power instead of relocating this one. PLL is 24 watts.
In other hand I suspect that maybe is a PAR problem. The point is that all plants tends to grow leaves from one level (6 cm approximately ) to the water surface where light is much better in terms of PAR

And the third it's a mix of both.

In general terms I see my tank doing really very well, and I would like to understand the root cause of my algae issue. I insist, for me at today, I don't really feel that I have an algae problem and I don't feel desperate about algae, just is part of this ecosystem.

I would really appreciate your thoughts about it.

Kind regards, Leonardo

I'm sorry to see no Tiger Lotus. Its absence is probably why you've got more algae than in previous photos. Stem plants can only use free CO2, so they are not as competitive with algae as your other plants, which might be able to use bicarbonates.

Suggestions:

I would skim off the water surface and get rid of that surface film. It's a reservoir of nutrients and possibly mycobacteria that you don't need and can easily get rid of.

I think you've probably got an excess of light for the current weak plant biomass. Before with Tiger Lotus, you were okay. I would add floating plants (frogbit, water lettuce, etc). You will not only decrease the light intensity naturally, but increase nutrient uptake.

If you add floating plants, you might need to add a micronutrient fertilizer if their growth is slow or they die out. I've started adding a little bit every two weeks. Big help for floating plants in more mature tanks. [Soil release of micro-nutrients (e.g., iron) into the water drops off after about ~~6 months.]

Additional thought, use a Siesta Regimen (2 hours of darkness at midday).

Hello Diana, i'm so pleased as always to read your kindly words.

In terms of "siesta" i have played with the photo period, from originaly 6x4x6 to 4x4x4 and later 5x4x6.

in 4x4x4 i had an issue where fishes went down to substrate and they liked "dead" so, i made a strong WC and restored to 6x4x6, and later 5x4x6.

This last configuration was the best --in my case--

For all your suggestion, ill try it and then let you know how things are going. But, don be afraid. Redl Lotus had 3 childs, its a matter of time yo can see more Red Lotus than before =)

Kind regards, Leonardo !
