bacteria

We just got back from 10 days away to find this weird, thick white substance in our sump (pics below). It's pure white, thick and is mostly on the display drain tube, and on the bottom of the refugium. There is some in the crevices of the live rock that in the refugium too. It blows off in...

Hi hopefully someone can identify this for me. I’ve never seen anything like this before. I tried to manually remove it but it’s surprisingly VERY hard to scrape off even with a toothbrush. It’s a 6month old system 125 gal with a VERY LIGHT bio load(two clowns, a gramma, softies and hammers)...

Hi everyone, I have had a pair of clowns for about 2 years, and over the last two days I noticed some white splotches on the smaller one. It’s been eating normally and hasn’t had any noticeable change in behavior, but I’m worried that it could be a disease. There haven’t been any new fish...

I used it recently to help fight back against cyano, and I see it being used quite often to help with algae. How does it work? Why does it kill the bad stuff, but the tank seems to be perfectly fine? Why is the good bacteria spared? How is it affecting the inverts? Does it accumulate and need...

Most of my arco have bubbles under the skin all over the place; and some of my zoa looks like mutated zombie; the plate coral gets star tips, and hammer tips are bloated. Seems some arco become green. I tested the water a while ago but everything on track. Alk around 8.5, Cal around 430 and Mag...

Hello guys! I just started my first tank about 9 weeks ago and I just want to see what you guys thought on the different types of algae and bacteria. Its all new to me so I really can’t tell what’s good or bad since it is my first tank ever!I if you guys have any suggestions or things that you...

Has anyone tried or know how to cultivate bacteria to be dosed back into the reef tank? I saw a video by WWC with the owner of Coral Morphologic, he did a tour of his facility and he mentioned that he was going to discuss how he cultivates Dr Tim’s bottled bacteria, but never got to it!

So I need to clean my filter, not necessarily replace media just carbon. Last time I changed the carbon I noticed a lot of gunk in there. I have a fluval 307 canister and I’m deathly afraid of cleaning it because of wiping out the bacteria and I don’t want to have a nitrite or ammonia spike...

I wasnt sure what heading to use for this question so I just put all the keywords in there. I have done research online but haven't found anything to be a solid enough answer. 3 Questions in short: - Is Saltwater Nitrifying Bacteria (SNB) exactly the same bacteria as found in Brackish water...

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?

Hello My Foxface was in Copper Power Treatment (at 2.5 ppm) for 14 days due to an ich outbreak. During Copper Power Treatment i dosed the water with 200 miligrams of Nitrofurazone to avoid any bacterial infections and did 100% water changes every 3 days. The last day QT i noticed a spot like a...

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...

Heyy guys, i need some help identifying what is on my sandbed. I have attached some picture od some sand grains under the digital microscope. Especially the red stuff if anyone knows please help id.

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?

I am planning on purchasing the Reef Casa Studio 12 aquarium kit.. Ive heard TONS of great reviews, however It come with 6lbs of dry aquarium sand and a bottle of bacteria. I am wondering if anyone has purchased this kit and purchased live sand instead... IF you did that route, did you have to...

Hello, I've just noticed this in my tank in two small areas. The red seems to floresce under blue light. Is it the dreaded cyano or maybe some algae. Any information would help. The video to me looks the best so hopefully you can open the file.

Hey guys, I have a bottle of Algae Barn Nitrocycle that I barely used to cycle my aquarium. I feel bad throwing it away and figured I’d see if someone was interested. I’m willing to give it away but the lucky person will need to cover the shipping cost or local pickup in the Bay Area. Cheers!

Hello all, I manage the saltwater section at a LFS here and have been having some issues with eye infections that seem to be targeting only specific species of fish and I am wondering if anyone here may have experienced anything like this. Rabbitfish, anthias, and angelfish seem to be the only...

Hey there, Somewhere I read that salinity level has an influence on the microbiome. It said that higher levels (above 1.025) limit advantageous bacteria's diversity/ability to reproduce and remain active. There's surely something about it, as one of the best aquarium bacterias product - Microbe...

I am waiting for my IM 15 to ship and arrive, and in the mean time have started cycling my aqua scape in a brute trash can. I was wondering if there was an agreed upon method for continuing to grow the bacteria culture until my tank arrives. intuition tells me that dosing to 2 ppm with...

[Little bit of info/background]: I had this 16g tank running, empty, for months. It never had lights on, only sunlight, and I thought it was cycled based on the ammonia/nitrate being none or low. A couple weeks ago my poor clown was dying and I tried to save him, so I put him in this tank (the...

This stuff showed up almost instantly, 7 week old tank and last few days I've been adding PurpleUp to help the corraline grow. I cant get a good pic but its a layer ontop of my rock and its VERY WHITE. I read it may be bleaching but this is new growth. I have very little flow in the areas...

I have 4 cromis and a few other fish and I need help identifying this outbreak. All the fish are fine except these dang cromis. One got very bad very quickly I think it go hit by a shrimp bullet or cleaner. But the other one has weird markings on it and it’s got no red and doesn’t look like...
