I raised up my LED pucks and increased intensity, trying to get better diffusion/coverage. I wasn't keeping a close eye on Alk, because it''s been very stable. Of course I should have realized changing the lighting would impact consumption. When I tested today it was down to 6.8 dKH, from 7.5 about 9 days ago.
Phosphates were also on the high side, so I did a 10 gallon water change with Tropic Marin @ 1.025 SG, and refreshed the GFO in the canister. I really don't feed all that heavily, so I need to increase filtration. I don't like leaning on GFO as my primary exporter.
I assume that I'm going to start seeing an alk drop between water changes if the Core7 dosing isn't keeping up, so I will need to adjust to find the right dose, I don't want to depend on the water changes to solve big problems like Alk, but to correct for the trace elements going out of balance (because I'm not doing ICP tests).
