Algae or bacteria problem

So I setup this tank about 4 weeks ago and I continue to have a white/clear growth on my rocks, sand, and glass. What is it? Also what can do to control it ?

What kind of skimmer and what size tank? This is one of those 'new tank' type problems, and careful water maintenance plus efficient skimming is your best course right now. I've seen this stuff happen in a very well set up but NEW set up tank, and it just went away with time.

What causes this in an old system? What is it?

Iím not running my skimmer as I was trying to build nitrates and phosphate as nitrate 1 and phosphate 0.00 with Hanna. I will turn on my skimmer if you think it will help clear it up. Itís a 330 with a vertex alpha 200 skimmer.
Tank is about 3-4 weeks running
I am middle of building bar

Id like to keep this discussion going. Hopefully Sk8r and others can chime in..

My 180g upgrade is going on 2 months wet. Quick background: Used dry pukani and dry reef grade sand to start fresh.
In addition, I soaked my pukani in Lanthamum Chloride for a month (so no phosphates) and have been running 1 cup of BRS HC GFO and 1 cup of GAC since day 1. Skimmer is on 24/7 and collects a half a cup of skimmate each wk. No other dosing.

I feed relatively heavily 3x a day for my 10 small fish right now.

A month ago, the expected diatom bloom occurred. Weeks later, the diatoms converted to green algae that can be blown easily off the rocks. Now, the rocks are covered in a similar white, stringy bacteria that looks like clumps of dust.

The rest of the tank looks too clean and I only need to clean the glass weekly. Even what grows on the glass is clear/white.

So I just turned off my GFO reactor for now, as Im concluding my phosphate:nitrate ratio is unbalanced?

Any thoughts ? Just let it mature more? Is this bc po4 limited bacteria?

Looks like it may be chrysophytes..a silicate based algae. Try searching Google images and see what you think. If that is the case, you can try algaefix marine to help subdue it.

I think you should get the biggest UV sterilizer and run it 24/7. I can’t tell you the name of your algae, but it is spreading thru the water column. Have you used a turkey blaster. Is it slimy to the touch. There are many differrent color cynobacteria.



This is a good link on nuisance algae, but does not identify what you have.

Very nice finished carpentry worrk. Your tank will standout with the way you designed your room

It really looks like this. I was told ROWA is best plan of action. Iím going to order some and see if it helps.

Good luck! If that doesn’t do it, I would seriously consider marine algaefix since I’ve seen it work as well.

Just a thought.. tell us about your RO/DI system. Whatís the TDS of your top-off water? Old cartridges can lead to algae outbreaks.

Well RO unit was taken down for 3 months so felt safer putting all new membranes and filters

So what does the TDS meter say today?

10 out of membrane and 0 out of DI
Tested water for silica and it was pretty close to 0.25 if not 0.00
Phosphorus rest with Hanna was 2
Which I think is .006ppm

Update. Tested silicates and they where pretty close to zero if not zero. Hard to tell. I put chemiclean and tank cleared up in about 5 days

Tanks started with dry rock and sand are prone to issues with odd bacterial blooms. That looked like algae, based on the hair look to it, but I strongly recommend you buy some varieties of bottled bacteria and dose them for a while. Or get some good live rock or sand to help seed the diversity.

Really cool scape by the way.

I have a similar bloom as OP. Started at the 2 month mark after diatoms disappeared.

Also started with dry pukani and sand, the former was soaked in LC for a month so its not a phosphate issue. Seeded with one bottle of Seachem stability bacteria.

Seems this type of bacteria bloom happens more nowadays based on forum observation. Its reducing as im scrubbing the pukani and changing filter socks.. i even pulled the GFO offline the last.2 weeks in case its related to a nitrate phosphate imbalance?

I agree. I also dont think I've seen a tank started with good live rock with an odd bacterial bloom. I think the common theme is more people are starting with dry rock and bottled bacteria. Thats why I made my suggestion of adding as many different types as possible/ and or seeding with good lr

What specific bacteria should ppl look at adding? With all the brands/strains out there, im inclined to try and wait this out for a month or so first for fear of adding fuel to the fire.

Ive heard ppl in past yrs suggest adding microbacter 7, but its prob all anecdotal.

I started with dr tims for my cycle. Then I added seachem stability, and prodibio biodigest. I think a few others. I also added pods, and a live sand starter "kit" from indopacific seafarms. I skimmed wet, changed filter socks daily, and added a UV sterilizer. I came out of it in about a week which is much faster then most from what ive read. It hasnt come back which I've also seen as a trend.

I tried to add as many different bacterial cultures as I could. I wouldn't recommend one specific brand as a fix, I recommend several sources of biodiversity.

I'm by no means an expert, this my personal experience mixed with my research on forum threads with people experiencing this issue and other issues with a dry base start.

Yes you will get strange bacteria booms with the bottle bacteria but I have setup 4 tanks with dry rock and found it normally cycles threw all the ugly phase quickly maybe 4 weeks. Now for different bacteria I purchased a microscope and started testing a few products out. Only thing I found that has live bacteria was turbo start. All other non refrigerated bacteria I have tried says bacteria is in dormant stage when fed they will reproduce. I used dishes and made 3.0ppm ammonia saltwater and let them feed but I didnít see any true population growth. Most product only had about 10% of bacteria movement. Seems like 90% of the bacteria never comes back to life. When I did the same thing with turbo start you can see the population growing every 24 hours
