Is that a daitom?

[dids22]

Hello!
The system is running about 5 mounth.

recently, a red-broown algae appears on the glass.

is this algae is a diatom?

Thank You.

I want to say No..if ur looking at "Hard" green algae looking stuff..I Believe it is Coralline growth.

 

BTW! Hiyas to NR!!

 

EDIT: Maybe Cyano? Damn, IDK now.

[dids22]

ok,
so what is the brown-red algae?

BTW, i can remove her easily with the magnet

is it like dust or powdery and easily blows off or is it slimy?

[dids22]

it is not slimy and it easily getting off.

[Cencalfishguy56]

it is not slimy and it easily blows off.

id say diatoms, it should burn itself out, do you do your water changes frequently?

[dids22]

15% every week - 2 weeks.

when i remove this algae it split to chunks and not to dust.

Difficult to tell from your pictures, but there appears to be a few different types of algae present in your system. Keeping up on frequent water changes is good practice. Ensuring your water source is of high quality, RO or RODI. Watch how much food you're adding to your system, don't overfeed. If these methods don't seem to resolve the issue then introducing some form of chemical removing media would be a good option.

 

Good luck!

It doesn't look like diatoms.

 

The reddish algae looks like cyano.

 

What is you filteration in the tank?

 

Have you tested nitrates and phos?

[dids22]

The water moves to the sump throw a filter sock, which i clean every weak.

there is a cheap protein skimmer of resun (sk300).

according API tests, nitrate is 0. (strong yellow) and phos is less that 0.25. ( i cant tell exacly)

[Clown79]

Cyano can be controlled and removed. It just takes some time and work. Do you notice at night it gets better and during the day it just gets worse? Clumps up upon removal?

 

Cyano will get the slimy and sometimes bubbly look but thats when it starts carpeting things-when its not being controlled.

 

You want to get the phos lowered. I don't use any media but you certainly can look into things like phosguard, purigen, or chemi pure. That will help reduce them. The question is where its coming from. Could be due to new tank, phos leaching from rocks? Over feeding?

 

Increasing flow helps reduce cyano as well.

 

In between water changes, when you remove the algae from the glass, you can suck it up with a turkey baster and remove it...even a brand new small strainer/fishnet can help. You want to not have it settle elsewhere.

 

During water changes, are you lightly vacuuming the sand? Try vacuuming up as much of the cyano.

 

Is the tank near a window? Cyano likes light.

 

 

You're doing great with the sock cleaning.

I definitely recommend weekly water changes, cleaning pumps and such monthly.

 

If its diatoms its all about time. Most diatoms are like a dusting, usually goldy brown.

I agree that the red algae looks like cyano. I would keep up with water changes atleast once a week, maybe time, and see if this changes. If you arent running any chemical media I would probably use a TINY BIT of phosphate remover to start.

EDIT: Clown posted at the same time as me. lol

[Clown79]

I forgot to add- this will help reduce the algae regardless of what it is.

 

Keeping nitrates and phos low will help with algae issues as well.

 

Your test may be reading 0 for nitrates because it being taken up by the algae.

lol cyano! Yes, idk why I was blanking out the other day, I was about to say red slime algae and I was like that's definitely not it

[Elizabeth94]

Algae is a pain in the butt, even to identify. We all could technically be wrong haha. I would have thought the same thing bc he first said it wasn't slimy. But then he said it came off in chunks- so I automatically thought of the cyano problem I had in my tank for while. Stuff is really slimy when you take it out and put it in your hands. In the tank it kind of "chunks" off when you scrape it from the glass.

 

Using Chemi Pure Elite helped a bit, but make sure you clean it out before using it.

yea I ised to hate cyano it would scrape off in sheets lol

[Clown79]

Thats the issue. There are so many algaes which look similar with slight differences. Lol.

 

Not to mention theres even different colours of cyano and diatoms.

 

I had a huge pain figuring out what algae i had when it struck because it wasn't slimy or bubbly but kind of a dusting and webbing. Not gold, not red but somewhere in between...i don't know what it was but the work i did got rid of it.

 

General rule of algae: figure cause, do a lot of work and it will disappear.

 

A royal pita

[dids22]

Do you notice at night it gets better and during the day it just gets worse? nope

Clumps up upon removal? yes, not as dust, more than like little pieces

The question is where its coming from. Could be due to new tank, phos leaching from rocks? Over feeding? i feed a little bit once a day. how can it leach from the rocks?

 

Increasing flow helps reduce cyano as well. i added last month a wave maker. so now i have 2 wave makers of 2000 l/h each.

Is the tank near a window? Cyano likes light. no, i covered the whole aqurium for 3 day, and it's help to reduce cyano. i also replace the light to new lamp.

the system is about 15 gallon.

i already have phosgurd in the sump. i moved it yestrday into the sock filter to have more flow.

Thank you everyone.

Rocks that are in water with high inorganic phosphates absorb the phosphates.

Those phosphates then leach into our tanks which we often remove with chemical filtration.

 

Some ppl do baths for dry rock before setting up theit tank. It helps remove as much phos as possible
