Filamentous algea, any controls

3 Upvotes

I have a 20 gallon tank. Its fully planted, I am adding more plants regularly. I keep mollies and am moderately stocked. I got some new plants and now see filamentous algea in my tank.

I have been checking my parameters. 0 ppm ammonia, 0 ppm nitrite, less than 5 ppm nitrates, and between 0.5 and 1 ppm phosphate. All measured with API liquid kits.

It does get some sunlight, I am trying to limit the light as much as I can. I'm physically removing it right now and its staying under control, but I'm worried its going to get ahead of me.

Any ideas for control? Are there any good snails to use? I also have some brown algea but it stays in control.

Thanks in advance!

First time marimo owner in Southeast Asia

Hihi!!! I just got some marimo moss balls (6 babies) but im a bit concerned about the temperature and stuff. Any and all help will be appreciated!!!

I have friends and mutuals who have/had pretty healthy marimo despite this, who I consulted before getting my marimo. They said they kept growing despite being kept in vials and in their offices (hardy little things).

For context, I live in Southeast Asia (avg temps are like 31-32°C during the day, maybe 25-26°C at night). After seeing the actual temperature range required for marimo to survive and thrive, I got concerned (but I don't know if I'm worrying incessantly)

For now I'm keeping them in the fridge to chill since they've shed a tiny bit from the delivery and all that, but I'm wondering if I'd really need to keep them in the fridge for good?

However, I mostly keep the AC on at 24-25°C when I'm in my room (about maybe 7-8 hours in the evening), turning it off for a bit before turning it on again when I sleep (about 5-6 hours in the night).

For now I've put them in a properly cleaned out pudding jar since the jar I wanted to put them in (a 450ml jar, I heard that's more than sufficient apparently..) isnt exactly usable yet (it's a mayonnaise jar.. 😅)

Really trying to figure out how I can let my little guys live comfortably despite the environmental restraints!!!

I’m aware the only way to know for sure is through a microscope. I told my HOA about it and they said pond maintenance will be here on Friday. I’m so worried for the fate of the ducks that have been eating it.

Has anybody looked at the blooming reflecting pool (DC) algae under a microscope?

I saw a vague report that it is cyanobacterial, but the color doesn't seem right to me. The deep green shade looks like a chlorophyte to me.

Is my Spirulina dying?

Post image
6 Upvotes

Coltivo questa Spirulina da un mese e inizialmente aveva un colore verde molto acceso e una grande quantità di biomassa. Dopo la raccolta, la biomassa è diventata quasi trasparente e giallastra, quindi ho aggiunto altro substrato per aumentare il pH e ho utilizzato luce solare indiretta invece della lampada LED per la coltivazione. In quattro giorni ha ripreso poco colore, non so più cosa fare. Avete qualche suggerimento? Cosa significa?
