Oceamo 's ICP-OES is an ultra-pure water analysis that checks the quality of fresh water (and therefore the operation of water treatment) . - We recommend such a check at least every 6 months, or when problems appear in the aquarium . Heavy metals like copper, but also nutrients like silicates and nitrates, are often introduced due to inadequate water treatment.
