I have mag24 on my 210 tank which i find a bit on the noisy side and my temp has also gone up a few degrees. this pump has a 1' outlet but i put a 1 to 3/4' reducer b/c the return bulkhead is 3/4'. could this be the reason for the noise and heat? I was thinking of putting 1' pipe about half way up then put in a union to reduce it back to 3/4". would that help?
