Hey guys

I had the same problem that started last year and ended when i got the carbon and phos reactor(December).I think it is some kind of bacteria.

here is a pic of how it looked last year July
P1050017.jpg


It is not yet as much as this, but it is starting to begin again.
I want to stop it before it becomes hectic again.
Does this thing live on phos?

Things that i did this last 2 weeks:
-10% WC
-Got me a 2nd hand ro/di unit from Likefish(he said it could run for 4 months depening on how much water i make before i need to replace the fist 2 stages, i only replaced the di ressin the 3d stage )

I will test my para.... tom
Can i test my ro water with the phos test kit or must there be salt pressent for the kit to work?

In the Koeberg blast radius
Hair algae and cyno(provided that ais what it is a few more pics will help:D), ouch.

Cyanobacteria - Marine Aquariums of South Africa - wiki (see guys this is why we want to grow the wiki :whistling:) Have a look at this

Cyno traps its nutrients underneath itself, so start by blowing it off with a Turkey baster or a powerhead (yes you will have to do it often:D)

The TDS of the R/O is what you should be worrying about not the PH, and although its worth checking I dont think it would be a problem yet

i'll add some more pic's today but it doesn't look like the pic's in the wiki.
I see alot of tiny bubbles in the dt and it seems to get more when my MH is on for a few hours, the tiny bubbles sit on all the rocks,corals and sand.

Hey war how can silica get into my tank i'm not using plasand for a dsb, i'm running araganite.

And in my sump(DSB) on the araganite there are black/dark Brown algae growing.

What did i do wrong that this started, my tank seemed ro be fine a few weeks ago.

TDS???
Phos 0.1 (this is high i know, but i took a test from ro unit's water and it is almost 0)
Kan it be feeding that made my phos go up( and i'm running a phos and carbon reactor, but i have never changed my carbon for 3 moths now my carbon, i need to change it)

Not hectic, natural seawater is between 0.01 and 0.3. If your new water is zero then cut back on feeding, also make sure frozen food's "juices" are not put into the tank, they will feed the Cyno.

Lanzo, judging from what I can see on the pic both the green and red are cyano bacteria.

The green looks like Lyngbya (Derbesia) and ussually grows under nutrient poor conditions. The only way to get rid of it is manual removal and Diadema. Here is a link for Diadema Urchins I

The red one appears to be Phorimidium (especially with the trapped air bubbles) and strange enough it also grows under nutrient poor conditions. Control via manual removal or Clibanarius tricolour. HermitCrabs

TDS = Total Dissolved Solids

You need to remove it manually and get yourself one or 2 of the Hermits to control in future.

TDS is Total Dissolved Solids - the total mass content of dissolved ions and molecules or suspended microgranules in a liquid medium.

Basically you need to check your RO water to make sure it is taking out all the chemicals, if not these chemicals will feed algae.

Total dissolved solids - Wikipedia, the free encyclopedia

Be careful if it is Phorimidium it can smother corals or damage coral tissue on contact "Black Band Disease"

If their has been a change in nutrient concentration in an aquarium it can mark the transition from Derbesia to Phormidium which is faster growing.
