“Zooplankton are microscopic animals that float in the world’s oceans and lakes, and for food they rely on algae, which are essentially tiny plants. Scientists found that they could make algae grow faster by shining more light onto them—increasing the food supply for the zooplankton, which should have flourished. But it didn’t work out that way. When the researchers shined more light on the algae, the algae grew faster, and the tiny animals had lots and lots to eat—but at a certain point they started struggling to survive. This was a paradox. More food should lead to more growth. How could more algae be a problem?“
“In the outside world, the problem isn’t that plants are suddenly getting more light: It’s that for years, they’ve been getting more carbon dioxide. Plants rely on both light and carbon dioxide to grow. If shining more light results in faster-growing, less nutritious algae—junk-food algae whose ratio of sugar to nutrients was out of whack—then it seemed logical to assume that ramping up carbon dioxide might do the same. And it could also be playing out in plants all over the planet. What might that mean for the plants that people eat?“

For the past month no matter how many water changes I do no matter what filter i use and now matter how picky I am about cleaning after feeding my 10 gallon will NOT stay clear.
The water turns this awful opaque lime green color that while it doesnt seem to bother the fish/snails makes it literally impossible to see ANYTHING in the tank.
Current inhabitants are:
1 very grump male betta
about 20 pin head sized baby mystery snails
1 very very large old man mystery snail
about 30 live plants of various types
Water parameters are a solid steady 7 PH 0 nitrite nitrate 0 ammonia 79-82 degrees (with heater)
Im starting to worry that the only thing that could cause it is the CO2 injector for the plants but im worried that if i remove that some of my more picky plants will die off.
I have probably done almost 80 gallons worth of water changes in the last 2 weeks alone which is killing my water supply. (I keep water in barrels that has filters and bacteria growth in it for emergency water changes)
None of my other 6 tanks are having this problem. Not even the 10 gallon sitting literally right next to this one so I’m not thinking environment like sunlight as they both receive indirect morning light.
The last days were exhausting. Because of the planarians and the CladophoraBeard algae I teared down the entire tank. I am glad I did because what I saw when I had taken out all stuff was shocking: The soil was full of planarians, tons of them, thousands maybe. If I had used medication against the worms and they would have all died in the tank the water would have been severe polluted by the dead worms… ergo only death of all animals. SO GLAD I didn’t do it.
Instead I took out the plants and am now curing them from the Cladophora Beard Algae… with “Easy Carbo” fertilizer (more an algae killer than a fertilizer) and H2O2. The plants need to stay in the boxes for at least 3 weeks now because they could still contain planarian eggs which need 2-3 weeks to hatch. Planarians are easily killed with mineral water but not their eggs.
I really hope I can get rid of the Cladophora Beard Algae entirely. It was taking over the entire tank…
Ugly thing, huh?
So I took out all plants and took out all stones and the root, cleaned it with hot water (not boiling!) and a hard brush so there were no Cladophora Beard algae left. This took me a while. This thing is really nasty!
The Soil was crowded with planarians. So disgusting! I took it ALL out of the tank and poured in entirely new soil. Also cleaned the entire filter and what does that mean? Correct: Tank Nuke… Reset.
This means now I need to change 70-80% of the water in the tank every day so the raising nitrite won’t harm the fish. Also I need to test NO2 every day now for at least a week or better two. The fish were one night in a bucket with another filter and some floating plants… very scared, those poor things. :’(
I tried to rearrange the hardscape as I had it before. Fish are now in the tank… set them back yesterday night … I leave the lights off so they’re not so illuminated and scared.. no plants to hide in the tank .. only a handful of floaters but even on their roots Cladophora beard algae was found so the others are still in the bucket.
Man, this is a real nightmare. Nevertheless I still need to buy Panacur against Planarians because those beasts tend to come back. But now there won’t be thousands worms anymore… I recently thought I saw them in the small tank, too… Will dose Panacur there, too. Just to be sure.
So this is why didn’t post or answered any asks lately :( Sorry, dears. I have a lot to do now every evening. Changing water in the big tank, changing water in the small tank (every second day since it’s a very small tank with only 2.5 gallons) and changing water in all plant boxes and plant bucket. I was busy until 11pm yesterday. x_x”
Got a new water chemistry kit as my other one was getting a bit old and I wasn’t sure I could trust it. Ammonia, Nitrites and Nitrates all okay! Great!
This is the first test I’ve had that includes phosphate, and I find phosphate levels are super high! Oh no! Is this bad? I haven’t tested phosphate levels of the tap water so I’m not sure if this is a tank only problem or not.
I’ve read that it mostly encourages algae growth and isn’t harmful for the fish. Hopefully this isn’t too much of a problem as its my Oto tank and they eat all the algae! (Plus the water is clear and I’m not having algae problems SOOO….?)
Irakli Loladze is a
mathematician by training, but he was in a biology lab when he
encountered the puzzle that would change his life. It was in 1998, and
Loladze was studying for his Ph.D. at Arizona State University. Against a
backdrop of glass containers glowing with bright green algae, a
biologist told Loladze and a half-dozen other graduate students that
scientists had discovered something mysterious about zooplankton.
are microscopic animals that float in the world’s oceans and lakes, and
for food they rely on algae, which are essentially tiny plants.
Scientists found that they could make algae grow faster by shining more
light onto them—increasing the food supply for the zooplankton, which
should have flourished. But it didn’t work out that way. When the
researchers shined more light on the algae, the algae grew faster, and
the tiny animals had lots and lots to eat—but at a certain point they
started struggling to survive. This was a paradox. More food should lead
to more growth. How could more algae be a problem?
was technically in the math department, but he loved biology and
couldn’t stop thinking about this. The biologists had an idea of what
was going on: The increased light was making the algae grow faster, but
they ended up containing fewer of the nutrients the zooplankton needed
to thrive. By speeding up their growth, the researchers had essentially
turned the algae into junk food. The zooplankton had plenty to eat, but
their food was less nutritious, and so they were starving.
used his math training to help measure and explain the
algae-zooplankton dynamic. He and his colleagues devised a model that
captured the relationship between a food source and a grazer that
depends on the food. They published that first paper in 2000. But
Loladze was also captivated by a much larger question raised by the
experiment: Just how far this problem might extend.
me is that its application is wider,” Loladze recalled in an interview.
Could the same problem affect grass and cows? What about rice and
people? “It was kind of a watershed moment for me when I started
thinking about human nutrition,” he said….
2015 09 22 Its nearly a year since I started this tank. After some months of doing no gardening, algae problems etc, now its becoming nice again. Newer pics upcoming. Also some pictures of my Wagtail Platy
oh my god ive been having a bit of a hair algae problem in my guppy tank and i just was going to remove some and i saw a guppy fry all tangled in it and it took me like 20 minutes of picking it up and slowly cutting the algae away(cause i went to pull it off and it looked like it was gonna tear the fry in two) and then putting ti back in a critter keeper and then repeating to get it untangled and it seemed in shock for a few minutes and i was literally having a panic attack thinking i had just killed a fish with my bare fucking hands and then it started swimming and i gave it a little fry food and it ate so i released it back in the tank. i hope it makes it
As you can see, I have an issue. I’ve been doing 20% water changes every day, and it isn’t helping. I’ve left the lights off for about 4 days now, no change. I’ve stopped fertilizing my plants, I’m feeding my fish less, and everything else I can think of. Any advice? I’m running out of ideas.
EDIT: there’s nothing stuck to the glass or the rocks, it’s just the water. The water is just so green it looks like it’s the tank.
Today I just looked at the 100g and the plants are actually going insane and growing how I wish. I’m eager to set up a second one of these planters and I may if I can clean out the one filled with soil in the back yard. I was ecstatic to find parrots feather actually growing wild in a ditch near our home depot. Aaron expressed extreme embarrassment when he didn’t get out of the truck with me to grab some. I’ve bought parrots feather that never looked this beautiful! I hope this bit snaps back (and that I have the chance to get more before it gets mowed down or something). It’s one of my favorite plants.
Now if I can just get my water lily to grow. This is the first year it’s taken so long to surface. I’ve had a huge hair algae problem over the winter and it may be choking it out… although I cleaned all of it out and I pull as much of the regrowth out as possible.
“I’ve always wanted to play an instrument” is probably the most frustrating thing you can say to a musician. Yeah, we’ve also always wanted to play an instrument. That’s why we play a fucking instrument. It’s not something that happened to us, it’s something we’ve spent vast amounts of time and money on.
Imagine if people said that to other types of majors.
“Wow, economics! I’ve always wanted to study business”
“I was an English major for a while when I was younger but my parents got tired of making me practice”
“Marine biology? So you’re going to teach? It’s great you’re so passionate about algae.”
Here’s the progression on my 10g tank. There’s so much lush in this one because of the dirt that’s underneath the substrate. I also put some root tabs down there and doses with co2 injection, seachem flourish and potassium. Having a bit of an algae problem though but the shrimps and ottos should handle it. The water is a bit cloudy too but that should go away in a couple of days. Having so much fun into taking care of this tank. I’m planning to turn it into a betta sorority tank soon.
