algea

I am new to saltwater tanks, my tank is about 3 months old. After cycling my tank the nitrates have consistently been around 0 to 1 ppm. I am starting to get green hair algae. My phosphates are currently at 0.2. Should I dose nitrates to help with the algae and to help lower my phosphates given...

Have an eShopps Mariner 70 that's been up and running since April of this year so about 5 months. We've been dealing with a ton of algea on the glass and on the sand. The mexican turbo snails and others don't really seem to do anything with the algea on the sand itself. What's the best CUC to...

I’ve been running this 15-gallon macroalgae tank with a pair of clownfish for about 7 months now. I do 15–20% water changes every week and feed carefully. Despite that, a slimy film has started covering all my macroalgae, the sandbed, and the rocks. I’m running activated carbon and Biofil by...

SIGHING OUT LOUD. So, I think im having an issue. I think its my circulation problem, but I'm not 100% sure. There is one section in mg tank that i don't think is getting flow, but i have no idea how I'm going to get flow in that area because my sand starts to move around way too much. This is...

Hi, I’m a bit puzzled by what’s growing in my tank. I asked my LFS, they could not identify it so they suggested to post here. My tank is 3 months old but part of the live rocks I used are over 10years old from a previous tank. After about 2 months, « green things » started growing on my old...

So the winter sun was hitting the side of my tank just right and I’m having an algae explosion on the glass. It’s made its way into the sump hoses. The snails, and the crabs and the pods help. But they don’t eliminate it. I have to manually scrape it off weekly. It has invaded my sump hoses now...

Hello everyone, I could use some help identifying the algea in the photos. It seems to have exploded over the last month or so covering all of my live rock. It doesn’t seem to bother my corals or anemones at all. I thought it was green hair algea so I went through 2 treatments of fluxrx with no...

I am just getting going after cycling so taking it slow, but over the past week to week and a half the tank has exploded with this algae all over. I am running the lights on low intensity and only for about 6 hours a day. I am asking as if this is Bryopsis I want to address it now before adding...

Hello! I noticed this white blobby stuff in my rock cave about 6 months ago, but couldn't find much info on it so I cleaned it out to be safe. It appears its back now though, and after doing some more research it sounds like it could just be sponged/filter feeders? Posting here to get...

I’ve had my 30 gallon tank setup for about 3 weeks, everything is healthy and good. But I am going through the algae stage, I’ll clean the glass spotless and the next day it’s covered again. Side question. It was originally brown algae on the glass but now it’s a green algae, does that mean...

This is the largest single bubble algae bulb I've ever seen and it keeps getting bigger. I kinda want to see how big it gets and not remove it.
