Do you swap all bulbs out at once? I've always staggered. If so do you reduce photoperiod temporarily to compensate or anything?Tank updates:
1) The tank equivalent of leg day at the gym... Swapped out old bulbs.
2) Added a Avast Marine Spyglass reactor XL and run both ROX carbon and GFO in it together. It's nice being able to ditch two terrible reactors for one good one that can run both media. For those curious, ideally you don't want carbon to tumble due to it releasing dust but if you use ROX carbon which is super hard and mix if with GFO in a true fluidized reactor like the Spyglass, it's perfect and I haven't had any issues with dust so far. Highly recommend it. Its easy to swap media too... Just pull the top portion off, leave the pump running, dump the old media out, rinse, add new media, put back on reactor body, put on rinse cap, rinse GFO into a bucket, and swap back to the normal cap and you're done. No lid to unscrew or thumbscrews either... No tubing to mess with too!
3) Still waiting for time to swap out to external skimmer, new larger return pump, rebuild manifold, and add the larger CaRX with peristaltic pump.
4) Oh, I'll be 38 lbs heavier by next week.
5) Went ahead and ordered the new gyres. My old ones were a bit noiser than I like for the display and just a tad less power than I want as well. Went with the new XF350s... Supposedly quieter, just a hair more power, and hopefully the cover on top helps prevent algae growth too. I'll move the two XF250s to the two frag tanks and use them in there instead for much better flow in the frag tanks.
6) High pH still going strong with 8.1 low and 8.5 highs. Not sure if I see faster growth yet but its only been 1-2 weeks.
