I can only agree on that if she has plenty of live rock, with powerheads to move water through it, in her tank to back up her biological filtration. If not, I would recommend turning the tank volume over a minimum of 5 times an hour through a sump. The vast majorty of filters are rated for turning the total tank volume over 5x per hour. 1.6x per hour is almost heresy! That low of a turnover is just begging for a constant NH3 or NO2 level.

Yes, this is a quiet one for sure but it runs very warm and will raise the water temp 3-4 degrees more than the Iswaki RLT 40 or even the comparable mag 12. T4 very easy pump to maintain and very reliable also...just runs warm.

Price does matter. I'm not willing to spend 200.00 for a pump. Thanks for the advice Chris. Dakota was the grounding probes I sent you what you were looking for, I never heard back from you on them.
