hello i have been out of the hobby for some years and thinking about slowly starting it back up. I have an old sealife systems skimmer without a pump, i believe a seastorm. Its small but gonna be with 38g with 10g sump. Its main chamber is 2 1/2"Wx10"H, total height 16" plus a 1/2" inlet. If i remember correctly i used a Rio600 pump on it. My question is whats equivalent/good needle wheel pump for my heartless skimmer? any suggestions would be great.
