Hi all! I have many plants in water, some are propagations and some are in water indefinitely. But among all of them these 2 seem to build up algae. I generally just top them up with water (sometimes with fertiliser) and occasionally Iāll do a full water change and clean the jar. Just wondering if this algae is beneficial or should I keep cleaning it out when it builds up? They both seem to be happy and are pushing out new leaves. Thanks!!
So the algae build up is caused by light hitting the water. Itās possible these two are getting just a bit more light than the othersā¦ even if in the same area. Itās perfectly natural and helps provide oxygen as long as itās kept under control the way you have been. OR, you can switch to a blacked out jar. No you wouldnāt see the root growth, but roots donāt grow in the sun they grow under ground so thatās ok. Itās honestly up to you entirely.

Eehhh I don't usually make a big to do about algae in my water props. You can use a few drops of peroxide to kill it. If left to over grow it will compete for nutrients. But generally isn't harmful

Paint the glass with nail polish. If you remove the light from where the water is, you wonāt have algae. You can also paint it a clear green and the algae will think itās in the dark but you can still see it (algae is green. You see green because algae REFLECTS green. If you only give it green light, itāll only be able to reflect and canāt absorb.)
