algae

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 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...

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...

Hello all! I hope you’re well! I’m currently after some answers as I can’t find them anywhere, I’ve had my planted tropical aquarium roughly 4 months, and yesterday I noticed what appeared to be these see through beige spots on two of my live plants and my seachem ammonia checker which is on the...

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...

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

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...

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...

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

Hi! I have bought a cory and died no long after max 1/2 days. I never had issues with putting fishes in my tank since I had it (6 months). I am worried my tank might have some toxic algae because it has a electric Blu green algae that's never been there before! So I am worried for my other...

Does anyone have any tips or tricks with plastic plant cleaner? Currently using some that comes in a tab form, you soak for 8+ hours, then rinse and soak with a neutralising agent for further 8 hours. I've done my rocks as it says you can use on those, algae has gone from green to brown, seems...

So I've had this roughly 50 gallon tank for just over a month now. I've done 1 water change of about 50% about 2 weeks ago. And I'm now noticing this brown stuff on the front glass, there's some on the back glass too. I'm just wanna make sure it just algae, or is it something I should be worried...

Hello! Going through the algae waves in my new tank, has been set up for a couple months now. All running smoothly and my cories and 3 guppy gals are doing great. There are a couple types of algae growing on the moss and wood I have in the tank, and I was wondering if anybody knows what kind...

Hello! I have a 125 gallon cichlid tank with a green terror, golden severum, blood parrot, jewel, convict, and a terror/acara hybrid (surviving baby). I’m looking for some bottom feeders to help clean up the tank a little bit, substrate, rocks, and glass. We’ve tried three plecos so far and none...

Before I start, I realize I should've taken a 'before photo' of my algae situation, but I didn't think about posting here until I'd finished cleaning. So the photo attached is the after photo. So a couple of weeks ago I noticed green hair algae growing on a couple of my plants so today I...

Hey Everyone I'm thinking it's green algae and I should cut down on the amount of time the light is on (12h atm). How do you balance algae and live plants with light?
