Hello fellow reefers, TWO QUESTIONS i. Anyone’s expert opinion on whether or not keeping a plant grow light in the same room as my aquarium is okay? ii. Also, could this artificial sun be the dominant factor in causing my excess algae growth? I have a quite young (6 weeks?) fluval evo 13.5...

So i’ve seen plenty of different methods to use H.P. to kill GHA The one that works best for me in to apply 1ml of 3% H.P. onto the GHA on my rocks (since they’re too big and have too many corals to just be taken out) My question is: can i use the one found at drugstores? Or do i have to go...

I've been having the Algae grow and i cannot identify it! I don't thing it's cyano because everything I read says it's green in freshwater aqariums but blue/red in saltwater aquariums. I dont know if I'm right or wrong but I recently changed from the red sea marine salt to the Coarl sea salt...

Hi averyone, So i had a ball of chaeto in my main tank for few moths, but it died due, i think, to the lack of light with coral growth, so i wanted to add a little "refugium" in my Max Nano (and i had my 1st nutrient spike because of the chaeto dying, i think) so i bought a Tunze Eco Chic and...

Hey all! So my tank has only recently been set up, it’s about a month and a half old. I used live rock that was being baked in a bucket for about 4 months prior to setting up, it only was ghost fed, no corals or anything on it, closed system. I’ve recently had this green slime algae pop up...

Hello everyone! About a week ago I purchased a Zoa frag. And I have noticed it’s more or less encrusting around the frag unlike the normal Zoas that I have seen and purchased. The picture will be posted below. But since putting it in the tank it seems to have some sort of algae hairs growing...

Hello everyone, I have a 7 month tank with which I always had an issue keeping my nutrients at a normal level, they were always low. About 2 weeks ago I started noticing what I believe was a type of algae I have not had before. Its ridgid and it really attached itself to the rock and now it...

So I got an algae problem and it slowly starting to spread faster. We’re thinking adding more filtration will work to compete against it. Like a skimmer, cheato, etc. What’s everyone thoughts on this? Sorry for the picture it hard to get a good picture.

I found this thing on live rock that I bought and I can't find what it could be. First, it kinda looked like regular red coralline algae but now it seems like some kind of macroalgae. It grows attached to the rock. Any idea what it is? Could it be harmful to the tank? Can I help it reproduce...

I changed my lights a week ago to a much better light and there are microbubbles and algae I think growing on the sand. Is this normal?

Hi all, I’m 3 weeks into cycling my tank. After week 1 I got zero ammonia, however, nitrite keeps getting higher even after doing 75% water changes. Yesterday, I noticed there are white spots on the heater holder, also, there are floating white stuff in the water column. This is how it looks...

Does anyone know what algae this is? It’s covering my top half of my rock. I’m thinking diatoms but not sure.

They seem to be pretty and harmless, I wonder if they are categorized as macro or not? How fast will they grow/reproduce and how large can they become? Thanks in advance!

Hey there, So we just got an algae for our refigum, but didn’t jolt down the name. We searched online to see if we could find it. However, we are having a hard time identifying it. Does anyone know what it is?
