I'll be filling the tank hopefully tomorrow and have a few questions I was hoping might be answered here.
The tank has been getting light for about 10 hours per day for the past 2 months and I know doing that with it filled would likely cause some algae. Should I just cut the light right away or slowly go down to 7-8 hours?
My filter has never been run and the media is all dry. 1st do I need all 3 layers of filter material? 2nd should I soak the filter media first?
Finally, I'm a little worried about fertilizing. I have Flourish, Excel, and Seachem Iron. I was going to follow the directions on the bottles and try for a homemade type of EI with 40% water changes weekly. Do I need NPK too or will my HC and DHG survive without them?
