Seachem

Seachem is one of the few aquarium chemistry companies that publishes the reasoning behind its products, which is part of why it has such a following among people who test their water rather than guess at it.

What we stock

• Prime — the conditioner most of our customers use, because it handles chlorine, chloramine and binds ammonia during a cycle
• Stability — bacteria for starting a new tank or recovering after a filter accident
• The Flourish range — comprehensive, Excel, Iron and the rest, for planted tanks at every level of ambition
• Filter media — Purigen, Matrix and PhosNet for canister and hang-on-back filters

If you are not sure which product solves the problem you actually have, bring a water sample in. Guessing at additives is how most people end up with a shelf of half-used bottles.
