help advice needed

I’ve been keeping koi for a few years and have been highly fortunate never to have a casualty. I recently did a 50% water change and hoovered the sludge from my pond—the usual clean-up after winter. I have replaced some filters by dipping them in the previous pond water. The pond is 2.4m x...

This white stuff showed up the other day, I think it was maybe the day after a water change? Does anyone know what it is or how to get rid of it? I first noticed it on the plants (none of the plants are new) and now it seems to be on the substrate too. My tank currently has 3 old guppies (I...

I've just recently got back into fish, and run into an old problem I've always had from my 20 gal to my 40 gal breeder. Tank has been up and cycled for years, just haven't been replacing fish until it got to the lone cory. I currently have a 20 gallon with 6 albino corys, 5 guppies, and a bamboo...

I keep seeing my platies gulping air from the surface, which I know isn't normal for them. Sometimes when they do it they also appear stressed, and will clamp their fins and/or fade in coloration (I have painted platies; the black part fades into splotches and you can see the orange underneath)...

Recently bought a bag of marine sand to use as substrate for my freshwater planted tank. I'm worried that it might not be suitable for the plants and fish inhabiting the tank. Can someone clear my doubts?

Hi everyone! This is my first post here, thank you for reading. My black mollies seem to be having an ongoing health problem. I received a 64 liter (17 gallon) fish tank, it has been running for a couple of years. It was stocked with a black molly colony, a Chinese algae eater, a pair of yoyo...

Hi there! So after watching and researching about planted tanks on the internet I've decided start one myself. I've bought the substrate, rocks, driftwood and plants to use in the tank and have cleaned them (boiled the driftwood, washed the sand, scrubbed the rocks, washed plants with hydrogen...

I am currently cycling (fishless) a 5 gallon tank with a HOB filter (TopFin) and Fluval BioMedia (BioMAX). That's not super relevant, but it's good to know and share. I have been dosing with Stability and the nitrites just started to spike. What I am not used to is figuring out how concentrated...
