Macroalgae helps, but it's not a standalone fix for large swings. Pair it with proper buffering for best results.

pH swings that large can definitely stress SPS. First, check your alkalinity levels—they should be stable around 8–9 dKH. Also, are you dosing anything? A calcium reactor or kalkwasser can help stabilize pH if set up correctly.

I'm upgrading from a 90 to a 150 gallon reef tank and I'm excited to stock it with more fish. I currently have a purple tang that somehow survived the great anemone disaster - it got stuck in a pump and wiped out my sailfin, hippo, and naso tangs. Luckily, the purple tang made it through. I'm ...

Honestly, it's tough to say for sure from those pictures, but I'm leaning towards mesenterial filaments. If that's what they are, then it's likely either some mechanical damage at the location or the coral is reacting to something. That could be anything from food to another coral's slime or even ...

I've set up a 45 gallon quarantine tank, thanks for the advice. I figure a little paranoia goes a long way in keeping my tank healthy.

I'm currently problem-free, just looking for ways to minimize stress when I transfer my fish to the new 150 gallon tank. I've had my fair share of bad advice from local fish stores in the past, and I've lost fish to ich. I'm eager to add new fish soon, but I want to keep the risk of disease as low ...

I've been out of the saltwater scene for a bit, but I've had a 90 gallon live rock f/o tank running smoothly for 5-6 years with the same 8 fish and no issues. Now I'm upgrading to a 150 gallon and I figure the hobby has advanced like technology, so I'm a bit outdated - my knowledge is limited to 7-8 ...

Been there, done that, and I'm sure I'm not the only one.

The frag itself might still be okay, but those areas with glue are probably a lost cause.
