Hi Baagedi thanks for your informative sharing. Since I will be setting this up and will need to get a new pump with the HK 150 chiiler, will you suggest that I get the eheim compact 1000 or other pump? The other one I saw in other forums where people was complaining that it was too powerful was the sicce syncra 1.0. What are your thoughts on that? Will the size fit as well?
