Hello all! New to Reef2Reef, back into the hobby after a few years. Hoping someone can put my mind at ease. My Waterbox 20 is 73 days old, I have CaribSea LifeRock and special grade live sand, cycled with Dr. Tim's. Smooth sailing up to 2 weeks ago, this algae has begun to reer its ugly...

I started up a 15gallon reef a few months ago and have found every inch of my rock is covered in this fuzzy growth. It’s over a good portion of my back wall and my algae scraper too. I’ve been using saltwater from the fish store and topping off with RODI. Only things in the tank are two...

I had this tank for over a year now and everything has gone good. had some algae issues over time but had gone away. now i have them again, do you know what i should do? should i just let be or use chemicals/ GFO? will it affect my anemone?

So basically this tank was set up last 2 weeks ago i transferred the old medias and some of the live rocks from my 55gallons going into a 120gallons and i dont know what are these cause i think it is the reason why my water is a little cloudy because of these microbubbles coming from the rocks...

Hello all, I’ve recently setup the tank of my dreams in my home 2 months ago. This past week, I noticed i’ve accumulated a brown algae that has taken over my whole aquarium. I just ordered a microscope to see what it really is up close, but was wondering if anyone could ID it, or give the best...

Hello, I started this Fluval 13.5 42 days ago. First added invertebrates after completing my cycle 22 days ago and fish 19 days ago (2 clown fish). I now have 2 clown fish, 1 watchman goby, 1 fire shrimp, 2 nassarius snails, 6 hermit crabs (mix of red, blue, zebra), 5 trochus snails, 5 bumblebee...

Hey can someone help me out please. My tank as been setup since 3/10/24. I've been noticing this white film on my rocks, should I be concerned? It's hard to get a clear picture because it's almost translucent. Stated with dry rock Live sand MicroBactor start I run UV for about 8hr a day 1.025...

Hello, I have had this tank set up since October 2023 and it’s always been very “green”. Here are some pics of how it looked along the way; very nasty! As much as I tried to clean it the algae always grew back overnight! The hair algae on the top is getting shorter but there is now very short...

Hey all, Happy New Year! :star-struck: I'm really struggling with my tank and wondering if anyone has any advice as I keep seeing conflicting info online... My tank has been up for 5 months now, its a Reefer 250 with about 230L volume minus rocks.. I've got x6 Blue/Green Chromis, x2 Juvenile...

I started stocking my tank with some beginner corals. I have some GHA but nothing my CUC, fuge, and tang cant take care of. Everything has gone somewhat smoothly other than my mistakes(water on floor in various rooms smh). I recently got a frag of GSP which was doing well for fist couple weeks...

Hi reefers, I have a preowned REEFER XL425, I started it from very beginning 2 months ago. A week ago it got through cycling so I bought a pair of Nemos, 5 mixed frags, 3 shrimps a 4 snails. Everyone look great. Except the fact, that the chemistry is weird and now the massive green outbreak...

Hey guys, New to the forum and to salt water aquariums. I have a ~6 month old tank and I keep battling algae that does not seem to want to go away no matter what I do. It looks like GHA, but I'm now wondering if it could be something else. My nitrate is 10ppm and my phosphate is 0.05ppm, so I...

I’ve got a new 92 total system volume tank set up and cycling since April 2023. Water parameters have been holding pretty stable: Alk 7.5 CA ~450 Mg ~1360 Nitrates are negligible The tank seems pretty clean except for this weird fluffy light brown/white algae substance that is growing on...

I've had a huge buildup of green hair algae on the back glass of my tank. I scraped all of it off, and added some snails to keep it in check. I've noticed that the algae growth on my live rock and sand has gotten a lot worse, and the snails/hermit crabs don't seem to be helping. Any ideas how I...

I have a fair bit of Brownish colored algae in my tank on my sand and green algae on my rocks. It’s a new tank cycled for about 2 months, but livestock only added 3 weeks ago. 15 gallon nano with SPS. a few snails and hermits cleaner shrimp clown and 6 line I am wondering if I should add a...

Hi everyone, hoping not to annoy asking this as I’ve seen similar posts. My tank is roughly 2 months old so very new and I am learning every day about the cycling and thank this group for so much info. Is this good ‘algae’ or should I be doing something different? My levels are great: KH -...

Hello! I've had my nano tank for a little more than a month now, and have a few questions. a few weeks back, I had a huge problem with red/brown thick algae growing on the rock and sand. it's mostly stopped growing there, but is now covering the glass. what's the normal timeline for a new tank...

This is currently what my tank looks like Question 1) the brown algae -read a lot about it being good, but how much is to much? I also have green algae on my glass. Question 2) close up of rocks with micro bubbles - is this okay? Question 3) should I be running lights on a normal day/night...

Hello everyone! I have a new tank, a little less than 2 months old and I’ve noticed this brown stuff growing in the back while pulling out any extra shrimp my fish didn’t eat. Is this a beginning stage of diatoms? What else should I expect if it is thanks for the help

Hey all, my tank is a little over 2 months old. Only have 2 super storm clowns in the 90 gallon tank. Noticed yesterday a couple small spots of algae on the sand. Under my lights it looks red. White light more brownish. Guessing this is dinos and start of the ugly stage. should I be looking at...

The other day i noticed these tiny green/brown strands of what i assume to be algae on the glass of my new tank under only the lit up side (one side does not have a light over it yet). The tank has been running for almost exactly one month in total and only 6 days with a light on one side...

Hi y’all, my Biocube has recently been pounced on by some sort of algae or Dinos i think. I wasn’t able to get the best pictures but it’s like brownish color and at first I thought it was just diatoms but now it’s long and grasslike and billows in the current. It’s all over my glass but only a...

Howdy! Hopefully this isn’t too boring, but figured I’d share my current build and progress. This is my first tank since I was a kid, so any and all advice, criticism or thoughts are more than welcome! Purchased a used Red Sea 350 (73gal display and 18gal sump), 2 AI Hydras, and a Regal Octopus...
