You can use Algicides, either chemical versions or barley straw. If the pot is large enough, algae eating fish (even if you just pop them in temporarily to deal with the issue and remove them to a proper tank after. There's also certain traditional set ups that help prevent, like clay topping soil ### Jay Dさんが2025-06-09にコメントしました I bought something that got here today off Amazon that says it’ll help with algae and is safe and non toxic to the plant, but as a newbie 🤷🏾‍♂️ I don’t know what I don’t know… ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/-_yB7X5_a-qgq33DsvEv1-bI6HOfXNSEBIXGLqBtMlc/0MDoX_JXS06K1VluFs18WA.webp?size=large) ### Waspinatorさんが2025-06-09にコメントしました Nerite snails are the single most effective algae eater I've ever had, but they're also escape artists #### Jay Dさんが2025-06-09に返信しました It’s hot in AZ so I wouldn’t want to put snails in a boiling pot!🤷🏾‍♂️🤗 ### Doryさんが2025-06-09にコメントしました Sooooo a super natural thing you can do is to black out your pot. Take heavy duty black plastic and cover the top. Make sure it’s sealed. Blacking it out for 48-72 hrs will kill the algae bloom without resorting to chemicals #### Jay Dさんが2025-06-09に返信しました That won’t hurt the plant I’m trying to keep alive!?🤷🏾‍♂️ #### Doryさんが2025-06-10に返信しました No it wouldn’t harm your plants. Shade loving plants can tolerate up to two weeks (closely monitor them though) and stem/sunloving plants up to 7 days. You’ll want to check it daily and monitor the algae levels. Once the algae is dead you slowly reintroduce the plant to light. Do a 50% water change making sure to pull out the dead algae and do 20-25% water changes semi regularly. #### Jay Dさんが2025-06-19に返信しました So I took your advice, I went out of town last Sunday and just got back today. I blacked out the pot with a Black trash bag and a lid to seal it and I came back to the Lilly pads looking like this. I’m hoping that the color will come back with the sunlight in subsequent days ![2件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/-_yB7X5_a-qgq33DsvEv1-bI6HOfXNSEBIXGLqBtMlc/0e7WzRrMT4mOPgL9CBE-kQ.webp?size=large) ![2件中2件目の添付ファイル](https://images.getplanta.com/v1/resize/-_yB7X5_a-qgq33DsvEv1-bI6HOfXNSEBIXGLqBtMlc/mjoQIQvmTi6p5GoZbOQM4Q.webp?size=large) --- _Plantaコミュニティ (https://getplanta.com)。閲覧はどなたでも可能です。投稿、コメント、いいねをするには、Plantaアプリをダウンロードしてください: https://getplanta.com/download_
