diatom

5 days ago I changed out the only filter sock and the GFO media. I pumped fresh tap water through the media reactor to get the dust out of the GFO. I forgot to empty the tap out of the media canister. 2 days later my tank turned to brown soup. I’m assuming this is a diatom bloom or brown...

Hello everyone, First time poster, and recent lurker. I have been wanting to get into the hobby for a long time and finally took my first step. I got a good deal on a Waterbox AIO 20 with some equipment. I felt like this was a good starting point for me to try and learn the hobby. It has...

May I ask what kind of dino I’m dealing with here and what else do you see? Thanks!

For the last few weeks I’ve been reliving my annoying battle with diatoms and hair algae. Used to have a big issue with it in my 10 gallon even though it was about 7 months old and now it’s started up again in my new 30 though it’s a bit less intense. 30 gal has now been running for 2 months...

Hey sorry if this has been discussed before, but this has been popping up around my tank and causing me to panic. I can’t tell if they’re dinos or diatoms. Will it kill my corals and should I add a clean up crew to my tank? The tank is a little over a month old with currently no fish and this...

I’m thinking this is just green hair algae and some diatoms, but just figured I’d check with some people who are more experienced. I also have hydroids which appeared two days ago. Any concern with them? I was told they would go away on their own?

Hey everyone, I am in need of some help here. I have been battling, what I believe to be, diatoms for close to three months now. I have recently checked my silicate level which was close to zero. I could not say exactly as it was a Salifert color comparing test. You understand these are not...

I have a pocket microscope Carson 250x. I made a videos of one sample of hair algae on different background. Can anyone identify which dinos are in the video? It all started when I had the stupidity to clean too much stone in the aquarium from algae with peroxide and vinegar and upset the...

So, no matter what I do, I keep having this reddish/brown coating come back again and again. The system itself has been up and running for 16 months, and I transferred it from a 60-gallon tank to a WaterBox Marine X 110.4 in August of this year. I've tried vacuuming the film off of the sand...

For reference I’ve had my tank set up and going since august 20th. I noticed the diatoms about 3 weeks ago and as of Sunday cleared off the rocks almost completely. Now we’re right back to where I was before, just 3 days later. I have provided pictures of the tank when the rock was cleared on...

Hey guys! Well my 310gal has been up and running now since the Saturday of Labor Day weekend. I’ve had lights on it now for a couple of weeks. Just put my permanent light setup(coral cares) on it last weekend and have them on a 10 hour light schedule at only 20% intensity right now. I used...

I have been struggling to get my Nitrates above 0.00 for months. Even with tripling feeding to 100 small pellets and about 1.5 cubes of frozen a day in my 65, it hasn't budged. I previously used a Red sea test kei, but now use the Hanna HR nitrate and ULR phosphate and same results. 65 gallon...
