water change queries

Hi! Im taking care of my first planted tank (20 gallons)and I have a few fast-growing species that are invasive in my area. I was wondering how to dispose of water when i do water changes? Boiling isnt really an option because of the volume of water and because this tank is in my office, not my...

And now the usually quiet filter buzzes. Idk what I should do now. Should I get a new one? If I do it might upset the cycle. I think it still works but I'm not sure.

I recently have sand substrate. When I try to clean it like I did with gravel, a portion of the sand gets sucked up into the hose. I have to scoop it back into the tank with a net. I don't want to lose substrate every water change.

I've decided that I wanted to help out with my parent's turtle tank. However, I'm afraid that with me doing newly frequent water changes it could harm them. For context, the tank has turtles and goldfish. Which will go into a pond eventually, but it's a big project. I don't want to harm them by...

I know that siphoning removes water and cleans out waste from under the gravel. But in water change, you have to replace the water. However, I haven't gotten it to flow the opposite way. With a bucket of clean water, I placed the siphon in headfirst and the plastic pipe end into the tank. I...

So... I did a partial water change yesterday (about 50%) and this morning the water is quite murky/cloudy. I have bought a new test kit (API freshwater master test kit) and all the readings are perfectly ok except the PH slightly lower than I'd like. I added one new live plant and a new...

Hi, I was just wondering, when I do water changes, should I try to get the fresh water up to the temperature of the tank, or will the heater compensate? Does it matter if I can't get a perfect match? If I'm adding pH buffer, should I add this to the water in the bucket before adding it to the...

Hi All, I have just started with my first aquarium with few golden fishes. After few weeks I saw some fungal infection on one of my fish for which shopkeeper suggested to change complete water with ( anti-clorine + blue medicine + green medicine ) , I tried that but due to this one of my...

Hey my tank is a bit of a hectic fish in cycle case. I've been doing 75% water changes the last 4 days and measurements. A Platy has started having fry. Should I wait until she's finished to do a water change? How will I know she's finished? I managed to get two fry into incubation box...

Hey :) You can read about my initial catastrophe here when I lost my Molly and learned about cycling a tank too late. At this point I'd tank about 5 weeks & lost 4 fish. Thanks to all the help in that thread. https://www.fishforums.net/threads/sick-molly.462043/ I've now lost fish number 5...

How exactly do you do large water changes in a heated tank? I’m doing 75% water changes in my bettas tank right now as he has fin rot. I let treated tap water sit out for a few hours to get to room temperature (about 70 degrees F), but his heater is set at 78. He is sitting in a cup right now...

Hi everyone, We have at least one swordtail fry in our tank, and I was wondering if we should do normal weekly water changes. I'm a little worried about harming or stressing the little one(s). We have a planted 125L tank with 7 small cories, 3 adult swordtails, snails, and the fry. The...
