    Water is cloudy then turns to green cloudy water every week!

    So I’ve had my 40 gallon tank set up for about a month or two now. All the rocks and decorations were in my previous 20 gallon tank (besides one new one). I only have one goldfish in the tank at the moment. I recently removed all the gravel and ornaments to treat anchor worm for 2 weeks. I...

    White fluff on plants and decorations

    Hi, I’m still pretty new to the aquarium hobby. I have a 70L (18 gallon) tank that’s been running for 4 weeks. I was a told by my local fish store to do a fish in cycle (a mistake I have since found out) so I am currently nearing the end of that (I think). Recently there has been a load of...

    Has anyone treated Cyanobacteria with salicylic acid?

    My Cyanobacteria is somewhere between under control and out of control. After following advice from here including reducing nutrition, adjusting light, tweaking the plants and following a rigorous water change schedule that lead to massive die off of my creatures and plants, I am still having...

    Betta keeps killing snails

    My tank has a serious algae problem. The only place to put my betta tank was by a window, and now there is a constant film of algae covering everything. Now, I wanted to add a nerite snail to the tank to help eat some of the algae, but, after moving around for a day, he stopped moving and died...

    White Fuzzy Patches on surface of tank water?!

    Hey everyone. I'm having an issue with my fish tank.. I recently noticed a white cloudy/fuzzy layer forming at the top of my tank water, on the surface and on the glass. It doesn't seem to be attached to any decor, mostly just the glass and water surface. I've actually been able to scoop it out...

    Green Grassy Algae

    Ever since I put a rock (I forget what kind) into my Betta's aquarium, I've started having trouble with a grassy moss-like-algae. I'll include pictures of it but not only is it covering the rock but it's gone everywhere including coating all of the plants and the substrate in a weird gritty...

    a small amount of white fuzzy looking algae has started to accumulate on some of my plants and around the intake of the filter. I recently re-aranged the plants and rocks to better suite the fish and I’m just wondering if this might be the cause, any help is appreciated

    Can liquid carbon help with a light/c02 imbalance?

    Hello everyone. My new 10 gallon divided low tech tank has been running about a week now. As the light was so poor on the hood I’ve put a tabletop led grow light shining into the sides.

    Moss balls & parasites

    I just got 2 Marimo moss balls because they r beautiful & low maintenance live plants. I have no other live plants in my tank so I'm hoping these work out. Currently they r washed & put in a jar for a couple weeks because I'm paranoid to put them in my tank with my fish. I was wondering if...

    What kind of bloom is this?

    Could it be a bacteria bloom / algae bloom? How can I tell the difference? This is in a 10 gallon tank. Not sure if this is a result of a water change (I do 15% every week) and a few weeks ago I had to replace the filter cartridge. Is that the reason why there is a bloom in the first place...

    I have a 55 gallon freshwater planted aquarium in my high school classroom. We added a heater last week because the tank was getting too cold with the hvac being set to turn off when school is not in session. I guess one of us bumped the timer on the lights b/c the lights were on all day...
