Don't use this pump on a 34G. I use it on my 15G nano and if I didn't have a chiller, the water temp would go into the mid-high 90's.
 You may consider something like a PanWorld 100. I have one of those as well and it seems quiet (though I haven't really used it, just a quick run to make sure it worked).

I am trying to not buy more equipment, I already have the velocity pump.
Anyone else have experience with these pumps. What sort of temp increase do they add normally? Would a fan over the sump be enough to keep the temp down? I just cannot imagine these pumps adding that much heat :-)

on a tank that small with MH lighting and a t3/4 pump, I would think your water temp would hover in the mid to high 90's. those pumps are horrible for heat transfer!!! A mag 7,9,or 12 would be a much better bet, and reasonable in price... There are other inline pumps I would recommend but they are very spendy and you seem concerned about cost. that t3/4 pump with a fan for cooling would still cook all your livestock, unless you had a wind tunnel of fans over the tank and topped up about 3+ gallons of evaporation a day while having the sound of a jet engine in your living room....
my personal opinion, those pumps are not worth their weight in feces....

Well, I didn't want to spend money if I didn't have too. I did not know the velocity put out so much heat.
What would you recommend then for a external pump that is reasonably quiet? I do not want a submersible pump.

any pump I would highly recommend would cost $3-400 for a low flow pump, Are you aware that mag drive pumps can be used inline as well? and have been by many with great success! they are also disposably cheap!

the smaller magdrive pumps used inline mounted on a piece of neoprane or other vibration reducing material will be as close to silent as your gona get, short of building a sound dampening box filled with sound insulation to encase the pump body

Could look into the Reeflo Snapper, quiet and would think by design low heat transfer.
Michika was putting one one her 28g
