    What is this? Is it harmful? How do I get rid of it?

    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...

    What kind of algae is this?

    Ambient light = algae?

    Quick question if you don't mind. I have a window about 5 feet from my tanks and while they aren't getting direct sunlight there is definitely ambient light coming through. My algae isn't out of control but wondering if you think it'd be a good idea to black out the window or if I should reduce...

    New planted tank light question

    So I had these lights from when I had a reef tank (Ocean Revive Arctic T247). Currently been running 2 weeks with 1 dwarf black ram my friend had to get rid of. I'm starting to get a redish brown algae on some of the plants and rocks. Had the lights set at 25% white 15% blue for 8hrs for the...

    Is this a new type of Hydra?

    I found these turbine shape micro-organisms in my tank. They seems like hydra where they have a stem and branches, but hydra branches are thin but mine is big.

    2 Eukaryotes fighting from my tank

    2 Eukaryotes fighting?, 1 in a turbine shape, 1 as a blob. They were found on my scraper while I was scraping algae. Edit: they weren't fighting, the keratella rotifer (blob) accidentally sucked onto the hydra (turbine shape).

    White Fluffy / Fuzzy Algae

    So i have added some driftwood to my tank about 5 days ago. The drift wood was sat in a bucket of water for a week beforehand. I have used this driftwood in my tank in the past, and dont remember having any previous problems with it. However it has this white fluffy / fuzzy algae growing to it...

    Acrylic Magnetic Algae Cleaner?

    We’re looking for a magnetic algae cleaner/scraper that is suitable for acrylic aquariums. I know there are loads on the market, but the trouble we’re having is finding one big enough for a 31mm thick acrylic aquarium in the UK. We’ve asked a few local aquatics stores and they can’t even order...

    How/when should I clean my filter?

    How should I clean my filter and when? I used to have a 70l uk filter and I cleaned it fully with tap water. Apparently that's really bad? I now have a 200l uk tank with a powerful filter for 500l - 800l. I've only had the tank running for about 2 weeks. I decided to do a fish in cycle, all of...

    I'm confused. I recently acquired 4 algae eating snails, I'm not sure what species they are. They arent nerite snails, they're covered in algae so I really can't tell. I've noticed one of them has a white mark on its underside, I can only see it when it's on the glass. I'm not sure if its eggs...

    Canister Skill Issue? Or Marineland Messup?

    I have a 30gal and switched from an HoB to a Marineland Magniflow 220 canister filter approximately 5 weeks ago (Im only using the provided media, no custom stuff). I left my HoB running for a week, just to help get the new filter up and running. For the first few weeks, it was working like a...

    Can anyone identify this white dust on anubias?

    Hi, I have a lot of tanks. All have been running fine for months. Some heavily planted. 2 planted tanks have just turned upside down and have no idea why. 1 had only green spot algae and I just removed the plant it was affecting before dosing with phosphate to fix this. The second tank had...

    Algae in new tank & plant issue

    I’m in the process of cycling my new tank and I now have algae growing. Am I doing something wrong? How can I stop it? Also I’m unsure if this plant is dying and what I should do. My other plants are thriving

    What is This!?

    I've never seen these before... are they algae? A worm if some kind? They look like tiny green anemones in my planted 30gal. The only occupants atm are 4 oto cats. I scrubbed them off the sides of the tank my snails are avoiding them like the devil, physically rearing to avoid them...

    Beneficial bacteria

    I just completely redid my 40 gal tank after most of my fish died from ich. I took water from that tank and put it into my old 10 gal for now, but it started to turn slightly green. My stepdad who keeps fish said I should put that water back in because it had beneficial bacteria that the fish...

    Brown algae in gravel

    I have brown algae in the gravel only at the front of my tank. I own a bristlenose pleco which seems to help but not entirely remove it, any advice on this? Thanks
