I am using Instant Ocean on SPS in QT. Instant Ocean has a dKH of about 12 and I understand a lot of SPS keepers shoot for 8. Is there a quick solution to this? Or just stick to 12 dKH?

But the reason I take good pics I don’t use too much blue you need a just your light for good pic
Do you do any post editing?
I would agree with everything in there. That being said, I use RC. My mag sits at 1600 to 1700. CRAZY HIGH right? I have lost some inverts to the high mag but my tank still grows SPS. Quite well actually. My dkh sits 9.5 to 10 typically. I do use Kalkwasser because my calcium sits between 425 and 465 and if I didn't use kalk or dose something it would drop too low.
Use some hydrochloric acid, found at Lowe’s or Home Depot, to drop you new water change water dkh down to 7 or something. Then let the water aerate until the pH comes back up. Use this method to SLOWLY bring your dkh back down.
I forget the amount of acid needed, but it’s something like 1mL per 4g of water.
Just to clarify, DONT add acid to your display tank, add to your new water change water. Also should mention tbat HCL is very dangerous so do this outside as it is usually fuming at these concentrations.
