09-03-2006 00:40 by john breen	Hi,I have a 350 ltr marine/reef set up cycling about 6 months . Having a problem or dont know what this is good or bad, Its like black melted plastic spreading over live rock and spreading very quickly help!

Use something like rowaphos this will remove phosphates and silicates. It will pass eventually the trick is to avoid adding silicates to the tank one way is to make sure you only use RO water.

15-03-2006 07:46 by Alan	John the suggestion of Adams is totally unnecessary and very risky diatoms are cyanobacteria my suggestion will work they are dependent on silicates and when there are no silicates there are no diatoms Adams suggestions are dangerous to say the least.
15-03-2006 17:54 by johnbreen	Thanks Alan will do as you suggest.
17-03-2006 16:27 by ADAM GUUMER	DIATOMS AND CYANO BACTERIA AT TWO COMPLETELY DIFFERENT ORGANISMS,DIATOMS USE SILICATES TO FORM THEIR CELL WALL STRUCTUREAND CYANOBACTERIA USE EXCESSIVE NUTIENTS.
20-03-2006 07:44 by Alan	We have obviously read different books then Adam. John my suggestion is good practice any way and will assist with prevention of nutrient build up.
20-03-2006 15:18 by ADAM GUUMER	Obviously as a marine biologist i must be wrong!!
22-03-2006 08:42 by Alan	Getting narky are we you may well be right however your suggestion of using the chemical implied you were a numpty clearly however you are not. I would have thought as a marine biologist you would be an advocate of not using chemicals such as those that you suggest. I will hold my hands up though you are probably right about the cyanobacteria and diatoms either way my suggestion will help deal with it with out the use of potentially harmful chemicals.
