I was skeptical at first, but Dr. Tim's Aquatics Clear Up for Saltwater Aquariums genuinely surprised me. My tank had been cloudy for days, and my filter just wasn’t cutting it. Within 12 hours of adding this clarifier, the water was crystal clear—like magic. No harsh chemicals, just natural flocculation that clumps particles for your filter to grab.

The best part? It’s safe for sensitive fish and corals (or so I thought—more on that later). I’ve used it multiple times after accidentally stirring up debris during maintenance, and a tiny dose does the trick. It’s like having a cleanup crew on standby.

But here’s the catch: while most reviews rave about its effectiveness (especially in smaller tanks under 20 gallons), one heartbreaking review mentioned a total tank wipeout overnight. That gave me pause. I double-checked my dosage and observed my tank closely after each use—no issues so far, but it’s a reminder to proceed with caution.

Price-wise, it’s steep for a 16oz bottle, but you use so little per dose that it lasts ages. Just be sure to follow instructions *exactly* and monitor your livestock afterward. For me, it’s been a reliable emergency fix—but I won’t lie, that one horror story still haunts me.
