Hi everyone!
I don't know if you all are tired of reading tank logs, but I thought I'd give one a go in hopes of getting some good input along the way! Plus I find the logs to be some of the most educational reads on this forum!
Here's my story- I have a successful freshwater 55g tank and recently started setting up a 75g marine tank. Last week I filled the tank with salt water and started up the skimmer, powerheads, filter, and heater to start breaking in everything and as a final check that everything worked as it should!
Three days ago I put in 80lbs of fully cured Figi live rock from www.premiumaquatics.com in my tank and have been letting it cycle since. The plan is to wait until water parameters are good, then add substrate, then eventually inverts and fish. Last measurement (10/5/07) showed: Salinity- 1.022, PH- 8.24, Alk- 6.5, Nitrite- 0.1, Nitrate- 0.6, Ammonia (free/total)- .02/.1
And that's where it all stands right now. Some pictures of the tank below. The 4th picture shows a purple growth of some sort in the middle of the photo. Can anyone identify it, and should it be removed?
Any comments or suggestions for my tank would be appreciated! I entrust you all to keep me on track and keep me from making any huge mistakes
. Thanks!
