Hello forum, I would like to ask a quick question before I order more parts, is it worth getting the MCP-655 pump over the DCP-4.0(also known as the DD CPX PRO, jingway dp1200, and several other rebrands) or should I keep my DCP-4.0? I would also like to know if I should get the Bitspower Watertank 250mm and replace my Danger den RAD reservoir? Thanks, cyansnow.
