Neil Allan –
Used SeaGel in my reef tank for three months. Water clarity improved noticeably, and I saw less algae growth. The filter runs smoothly and the gel stays effective over time. No fish stress reported.
Carl Paige –
Good for removing phosphate and organic waste. Works well with my protein skimmer. Slight color change in the filter media after a few weeks, but no issues with tank health.
Jan Oliver –
The product performs as described. Phosphate levels dropped significantly after a week of use. Bead shape allows good water flow and doesn’t clog easily.

Used in a marine tank with live corals. No adverse effects on corals. Water became clearer and less cloudy. Recommend for reef keepers with high organic load.
