seabass Posted October 28, 2020 Turns out my T5HO bulbs are well over two years old; so I replaced the T5HO bulbs today with the following: Giesemann Powerchrome Actinic Blue Giesemann Powerchrome Actinic Blue Giesemann Powerchrome Aquablue Coral ATI Aquablue Special I purchased the Giesemann bulbs when Drs. Foster & Smith went out of business. 3 Quote Share this post Link to post

da1001 Posted October 30, 2020 Those RFA's look nice. I try to get mine to lay flat but he likes to hunch half on the sand and half on the rockwork, its annoying to say the least! 1 Quote Share this post Link to post

I didn't test pH when alkalinity was higher than 16 dKH, but that might have been interesting. My new batches of Reef Crystals are mixing to around 11 dKH, so that's my current target. 2 Quote Share this post Link to post
