So, I'm a bit lazy on testing except for Alk, which I've been trying to get back up into a better range. Did a full set of tests this morning:
- Alk: 6.3
- Calc: 405
- Mag: 1420
- Nitrate: 0
- Phosphate: .03 ppm. (1 on Hanna HI736)
I'm still fighting hair algae, but it's been a little more under control.
A few hair algae questions for anyone seeing this:
- Will a toothbrush hurt SPS? I have a few frags where there is hair algae at the base, but it's hard to get at without brushing some of the coral itself. I've always been a little gun shy about doing anything that touches my corals (and probably should know the answer to this after a decade+ in the hobby)
- How do you all get into the crevices? I've got some branching live rock and it's hard to get in there. The hair algae seems to now be staying away from areas of my rock that I can completely remove it. However, where I have trouble getting it all off, it continues to grow because none of my CUC seems to be able to get it cleaned off.
- Any other thoughts other than keeping up with water changes and hand picking on getting it under control?
