シーケム ハイパーソーブ

The water parameters in my tank have stayed perfectly stable since I swapped out my usual carbon, and I love that there's no pH swing to worry about. It's been almost two months now and the organic waste removal is still going strong, so I'm definitely getting my money's worth.

I was skeptical about switching from carbon, but this stuff removed the yellow tint from my water in just two days. It’s nice that it doesn’t mess with pH either, my fish haven’t shown any stress.

Water parameters stayed rock solid the whole time it was in my filter, which is exactly why I switched to a synthetic adsorbent instead of messing with carbon. The yellowing wasn't extreme, but this handled a heavy bioload for a full month and the tank still looked crystal clear.
