Hey all, new member here. New to hobby, been keeping freshwater about 10 years.
I've got a 29 Gallon tank up and running. 7 Days ago I added partially cured live rock and 2" of live sand along the bottom. I started running the lights 7 hours a day, increasing an hour a day up to 11. Tested the water day 2, 4 & 7.
Salinity: 1.24
Ammonia: 0ppm
Nitrites: 0ppm
Nitrates: 20, 30, 10 ppm
The nitrates are the only thing that has fluctuated in the last 7 days. I also noticed a red-brown algae bloom over the top of the live rock on day 4, which has slowly grown.
My questions are:
Is the algae a normal part of the cycle? Or am I running my lights too much (2 x 55 watt T5 power compacts, both bulbs are 50/50 bulbs, half 10,000K and half Actinic) ?
Is it possible the tank has cycled? The rock smelled 'fishy' when I bought it, so I have to assume not, however I am surprised I haven't seen an ammonia/nitrite spike, unless I missed it in between tests. I plan I waiting at least 8 or 9 more days before adding the cleaning crew anyway - I was just wondering!
Thanks for the help!
