Hey guys, 6 week old tank and i noticed a stringy white thing that’s attached on my rock. Any ideas what it is and what’s causing it?

Good afternoon! I have a 6” magnificent Foxface that I ordered online that I’ve had for 2 weeks now. Still a little shy, but has been getting much more bold in the tank. The problem I’m having is with feeding it- the fish is only grazing in algae in the tank. I feed LRS reef frenzy and mysis...

Hi All, Can anyone confirm if this is Green Hair that's starting to grow on some of the rock (the lighter rock was dry and has been curing in buckets with the live pre-tank). Tanks is around 6 weeks old and all levels are OK. I have some 5 turbo and 5 neccarious snails alongside a Foxface and...

I need to clean a rock out of water since it's full of GHA and I estimate it will take about 30 minutes to scrape it all off, spray H2O2, let it sit, then rinse with SW. I also have a mushroom on this rock but since it's on the lower part I can keep it submerged. Also, is spraying H2O2 really...

Hi all, I had a turf algae issue and used reef flux to kill it. I moved my chaeto to another tank during the treatment. It has some turf algae knotted into it. I do not want to add it back to the refugium with the turf algae in it in case that could add it back to the system. Is there a way to...

Hey guys, i’ve been getting this browny slimy coating over my glass but predominantly where my zoa is. I initially thought it was the zooxanthellae since it was sort of similar in colour, but now it’s in many more places. It comes right off when i clean the glass, but anyone have an idea to what...

Pretty new tank, started to get a build up of detritus a few days ago and now there are small bubbles forming on the sand and the rock as well. Any ideas what this is and how to fight it before they blow up?

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...

Hey y’all so my tanks about 2 years old now I’ve been having phosphate issues which have caused major algae Dino cyano who knows what was at .92 phosphates now at .16 looks like it’s going away hopefully while i was fighting it I’ve been siphoning it off the sand bed and picked up too much...

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...

Tank: 10 gallon AIO TL;DR neglected tank, what’s the best way to clean up so my pump quit working while I was out of town, took a while to notice, order new pump, install, etc. in the mean time, I’ve developed some hair algae, algae growth on the glass, and all kinds of algae along the glass of...

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! I have this weird brown algae growing on some of my corals. It looks like it could either be dinos or brown hair algae but it only grows on a few of my corals plugs and only a couple spots on my rockwork. The tank is about 5 months old. I run a protein skimmer just did a 20% water change...

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.
