Tank looks to be coming together. I have a Nuvo 20 Peninsula. Just starting the cycle. 20lbs of sand with the rock placed on the glass first. Branch is mounted to a tile with epoxy.
I too have an AI light, Hydra 26, my plan is to set using the rotary setting. 15-20k is the spectrum recommended to be by a coral shop near me. As the tank is empty, Ill start about 30% power and then adjust as needed once I add corals. 8-9 hours is whats needed so Ill run from 11-8 or 12-9 as I can enjoy it in the evenings. Using the simple spectrum will adjust the levels for me to get the right blues for the corals to grow. I also upgraded the pump to a Sicce 1.0 and is super quiet sitting on my desk.
Are you planning on adding an ATO? I would like to and still researching whats fits best. How is your evaporation in the winter on a 20g
I like the rubble on the bottom so you can have islands of corals. I have a few small pieces too that need to be put in.
Here is where I am at. Water in for a day with DR Timms as of today. Just starting the cycle and will let it run for a few weeks this way. I have also a Jeabo PP-4 that I need to install shortly. This will give me plenty of flow plus a later battery backup for loss of power.
