Hi All...
I have recently set up a 180 gallon planning to be FOWLR tank, it has been running for almost seven weeks now. It has a wet/dry trickle filter and several powerheads for ciculation (turns over about ten times an hour), skimmer in sump producing a third of a cup brown skimmate daily.
I have at the moment about 100 pounds of live rock (been in for five-six weeks) and plan on adding a further 100 pounds in the coming months.
My tank when throuh the intial cycling stage (nitrite spike etc) when the live rock was first added and the water parametres are as follows and have been for a month.
SG 1.025
Ph 8.2
Nitrite- 0
Nitrate- 0
Ammonia - 0.5-1ppm
Why is my ammonia still detectable? (have confirmed results on another test kit)
I have not yet done a water change as I was told by my LFS to wait until my tank stabilises.
my diatom population is slowly decreasing but I am currently experiencing an outbreak of red slime algae (cyano), is this to be expected?
I have no inhabitants in the tank except for a crab and a couple of urchins and marco algae species that hitchhiked with the live rock, doing well and growing.
Should I be doing water changes now/ removing cyano?
What is causing the cyano? I cant see excess nutrients being a problem as there are no fish or feeding as yet.
Any ideas would be appreciated. :?
