You can add a little fish food if you’re worried about starving the bacteria, but really, microorganisms can live pretty well off their dead brethren.

ETA: It is super important to test for ammonia, nitrite, and nitrate at least once a day if you add fish food and live fish to a new tank, even when using established filter media. It doesn’t take much fish food to crank the ammonia up to a point where it’s hard to get it back under control.

No, large water changes will not typically crash an established cycle. The vast majority of the bacteria that break down nitrogenous wastes live attached to surfaces: filter media, hardscape, substrate, and plants. Filter media are designed with surface area in mind: the hang-on-back (HOB) filters using the plastic cartridge covered with fiber floss has lots of slots to allow water to pass through and over the fibers, which are frizzy and are easily colonized. Canister filters hold stacked baskets of media like porous, ceramic rings that are designed to maximize surface area and house a ton more helpful organisms than even the fiber-covered plastic cartridge.

When starting a new tank, it’s a good idea to throw some of your existing, healthy tank’s filter media (or plants or hardscape) in to jump start the community of microorganisms that keep your aquatic buds safe. You can use a friend’s, but only if you’d trust them to care for your fish at least as well as you do, as harmful organisms can also attach to surfaces and be carried along.

It’s true; we love the dwarf shrimp for their looks, not their abundance of caution.

Squirt it right on top of the algae, not in the area. Peroxide’s not a dangerous toxin that lingers, but it’s reactive oxygen that disrupts bonds. (That’s its sanitizing super power.) It can chemically burn if left in contact with skin for too long, so I wouldn’t risk using it on hardscape inverts are sitting on or too near your fish. (The burns aren’t serious for humans but I don’t know how a fish or snail would do before the peroxide dissociated.)

If you need to, put some tank water into another container and treat your hardscape in that so you don’t risk anyone’s safety.

First thing to do is remove as much as you can by hand. I usually twirl it around a barbecue skewer and pull gently until I get a good wad of it, like getting cotton candy onto a cone. Keep doing that until you can’t find any more clumps.

Next, do a water change to reduce available nutrients in the water column. If you use plant nutrients heavily or tend to overfeed like I do, 50%+ is a good place to start when it comes to starving out hair algae. Keep doing water changes on a regular basis (I shoot for 10-25% every week, but in reality it’s usually every two or three weeks) to keep the overabundance of nutrients in check.

You can spot-dose store bought hydrogen peroxide (the regular 3% kind) with a dropper onto remaining patches of algae; they should start to die off immediately and change color to red or brown. Those bits can then be pulled out or siphoned up. Used in small amounts (like a couple droppers’ worth, not a quarter bottle), peroxide shouldn’t hurt anything in your tank and will quickly break down to water and oxygen.

After those initial steps, keeping control of hair algae involves getting your plants to outcompete it for food. One really easy way to do that is to add more plants and keep using the same amount of fertilizer. You’ll know when to increase your dose when the plants start looking like they’re deficient or not growing as well as before; make small changes and wait at least a few days to see how they respond.

Aside from more plants, a nerite snail is a great addition to your cleanup crew. I’ve never had one try to escape before, but a female nerite will lay eggs on your hardscape. They’re small and white and look like sesame seeds. The eggs won’t hatch in fresh water or harm your tank.

Good luck! I know hair algae is a hassle and hope this works for you.

Bettas are big on personality and intelligence in general. I’ve had some chill bettas who’ve shared a ten gallon tank with shrimp, and ones who have eaten all the shrimp in a couple days. Some ignored the other fish in the tank, and one had to be put in his own 5 gallon tank because he would chase everyone and stress himself out.

My favorite betta would refuse to eat the pellets I got him unless I ground them up into smaller pieces with a mortar and pestle. He totally could, he just didn’t like to. Once he found that I would break them up into smaller pieces for him because I didn’t want him to starve, he stopped responding at all to whole pellets and would stare and wait for me to grind them up before swimming to the surface. “Pardonnez moi, mademoiselle, these are unacceptable”

This right here is why people buy display hutches to hold glassware, change my mind

That’s really incredible stuff, especially given how not-fun that part of the game was 😅

It probably is still legal, but it’s not something I’ve looked for in like a decade. We do have products that use ground kernels, but those aren’t good to use on skin–the milling process doesn’t produce uniform particles and the pointy bits tend to compromise the barrier skin provides with very small tears.

I completely agree that plastic isn’t necessary for good soap, I just like it. I would definitely buy soap made with ecologically responsible plantstic at least once.

More importantly, using safer, scalable, completely biodegradable, algae-based polymers opens up so many more options for single-use products while simultaneously improving environmental quality. Farming algae and seaweeds removes a lot of contaminants from the ocean, like agricultural fertilizer and solid waste runoff. If we can truly scale up ocean farming responsibly, it’ll be its own “teal cascade” in which the benefits multiply with each step in the process.

1. Farming algae/seaweed doesn’t require the use of inorganic fertilizers when you grow them alongside shellfish like oysters, clams, and scallops

2. Increased protein production through shellfish reduces reliance on agricultural livestock for meat (which is incredibly damaging to the environment)

3. Algae/seaweed can replace fossil carbon in fertilizers and plastics, and reduces cattle methane emissions by 20% or more when added to their regular feed

At each step, we can take more and more petroleum out of the equation just by using methods that are better than sustainable, they actually remediate existing harm.

Plus, I get my scrubby soap back.

I cannot possibly be the only person who misses the soap with the plastic bits in it. If they could do that without the environmental damage (I’m looking at you, Great Lakes ecosystem), I’d be into it

Part of me agrees with you; part of me is yelling, “Yeah? Many? Name five!” (Admittedly, that’s the American part and it’s kind of an asshole.)

I feel like IT could yell at OP for a little bit, but would ultimately have to stare the fact that they allowed non-privileged users to just change the operating system square in the face. Like holy hell, 500 employees and anybody can just be like, “Hey, maybe I’ll make a major OS change today because why not?” What else are they letting happen?!

Yeah. Cats are really, really good at making it clear they understand when you’re calling for them and they’re choosing not to respond. I figure it’s fair; there are plenty of people I wouldn’t cross a room to talk to, either

It takes all kinds of people to make the world work. Glad you’re here!

This job sounds even worse than being a quality control tester at a jack-in-the-box factory

I want a script that fills in other data brokers’ contact information!

I interned with a hematologist who was incredibly excited to show me a slide of hairy cell leukemia, the one case he’d seen in his career (like 20 years by then). That was just a microscope slide, I can’t begin to imagine how bad the loss of research samples would be on someone.

The failure was in supplying nitrogen to an array of 16 freezers. Unless samples were split and stored in different arrays without the same coolant source, they’d still have lost everything.

It would be easy enough to create multiple sample sets to be stored that way, but it’d add an extra variable researchers would need to account and test for in their work as well as reducing sample capacity by at least half. A place as mighty and prestigious as the Karolinska Institute probably has a ton of graduate researchers, too, and everybody knows those people just graduate and leave all their shit behind without clearing out old samples.

The whole thing is heartbreaking.

I’m happy that researchers are publishing their data on this, but I wish they’d include discussions of some of the bad faith antics organizations are pulling while pretending to push return-to-office (RTO). This goes way beyond reasserting control over their employees, like the firms owning those buildings and expecting rent from same-site retail businesses that need the higher foot traffic RTO could bring or wanting to do a round of layoffs without paying for severance.

Let’s do Elsevier next!
