I start my tank update with the story of how I used my Sep '17 frag swap bonus coral ticket to get a frag of a coral I apparently already picked up at the Feb '17 swap, from the same person (
@anathema)! Apparently I really like multicolored acropora tenuis. Some of the more colorful acroporas are tenuis: Honewrecker, Walt Disney.
Here is the piece I picked up in Feb, photo taken last week:
Here is the piece picked up in the Sep. swap:
At least I can feel confident that the new tenuis should do OK, since the old frag has persevered through six months of my noobiness and two heat waves. The big challenge will be ensuring the mini colony gets adequate flow and and adjusts from halides to Kessils.
Since my display tank algae finally disappeared for good since April (thanks to upgrading my chaeto light to a Kessil H80 and adding emerald crabs), I've been experimenting with feeding corals more in an attempt to increase growth rate. Feeding has helped a lot. I recently discovered the tank iron levels were low and started supplementing. Potassium and iodine are ok, Ca Mg alk have been good and constant. However, my nitrates are stuck at 0 and phosphates are pretty constant at ~0.1, those were measured right before a water change. I'm thinking about trying nitrate dosing up to 2ppm to see what that does. Does anybody suggest a particular nitrate supplement or other method to increase coral growth?
Adding nitrate test (since the color changes are highly subjective)
