I recently installed a "tank water" faucet on my sink next to the main faucet. It is tapped into my auto water change chloramine removal system. I mainly use it for brine shrimp rinsing and filling the ziss hatchers. Before installing I cleaned my sponges, hatched and rinsed brine shrimp daily in chloramine water with no negative effect. I now clean and fill using the filtered faucet.
