JBL ProScan Recharge - Refill

I was relieved to find these refill strips work seamlessly with my existing reader, and the water analysis comes back crystal clear every time. The strips are easy to handle and give consistent results for monitoring my tank’s health.

These strips fit perfectly into the reader and the results match what I get from the liquid test kit, so I feel confident using them for weekly checks. The recharge pack saved me from buying a whole new system.

My last batch had been sitting around for a while and these strips still gave me a quick, clear reading on my ammonia levels. The packaging is compact and keeps the strips fresh, which is exactly what I needed to avoid wasting money on a whole new kit.
