Chillers for planted tanks--flow rate dilemma
I hope I'm not rehashing past threads, but I'm wondering how chillers can be use effectively on planted tanks given flow rate issues.
Generally, recommended flow rates for chillers seem completely out of whack with what folks would be running on planted tanks.
In my particular case, I'm looking to source chillers for a couple of ADA 45Ps (which will probably have true water volume of 7-8 gals). If the appropriate turnover for a planted tank is 2-3x tank volume per hour, I'm looking for an ideal flow rate of 25 gal/hr(?). All of the smallest chillers on the market recommend a minimum flow rate of ~150gph. I won't be able to achieve anything close to that on the eheim 2213s I plan to run, especially with all the in-line equipment I plan to add on...nor would I want to for the sake of the critters and plants in the tank.
According to the manufacturer of the smallest in-line chiller I could find (AquaEuro 1/13hp) that isn't discontinued (...all the 1/15 and 1/20 hp chillers are no longer produced...what's up with that, btw?), whom I emailed, running lower than recommended flow rates would result in freeze-up and damage to the compressor. They recommended that I don't buy their product.
So I feel like I'm outta luck... How do other folks run chillers in their setups? If running at significantly lower than recommended flows, have you experienced any issues?
