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?

You could run an additional inline pump and use something like a poppy glass outflow to calm the flow.

For example, intake, canister filter, heater/reactor/whatever, iwaki pump, chiller, poppy outflow.

Yeah, micro chillers are very hard to find, they don't make them any more really. In Asia they are more common.

yeah i could use a pump to get to the recommended flow, but wouldn't 150 gph be ridiculous on a 10 gallon tank?

reef tank flow rates on a planted tank doesn't seem reasonable to me...like fish and plants just blown around everywhere? i dunno, maybe I'm wrong.

A lot of the high tech tanks you see are doing 10-20x for flow rates.

really 10-20x? and fish/shrimp are ok with that?

the AACH10 still requires 160 gph, but thanks for the suggestion.

Where are you seeing that it requires 160gph?

cheaper to buy a used dorm fridge and easy to find. just plumb through the side of it. you can run whatever flow you want through it. control the temperature by tweaking the temp of the fridge, the length of hose coils you run on the inside, and if possible (in your case) the flow rate.

Every site says to use a 160gph pump at the low temperature range.

Also logically if the 1/13hp chiller I was looking at required that type of minimum flow, the 1/10hp AACG10 chiller would require something similar or higher than that.

I want precise temperature control, and energy efficient cooling...the dorm fridge probably fails on both fronts there.

The poppy glass outflow lily pipe should break up the high flow quite a bit.
there is also a stainless steel outflow pipe that looks like an intake.

Spec says 250l to 1200l. Them suggesting that pump is them pushing their product if you ask me.

Looked into a sump? Or one of those peltier coolers run inline with a canister filter? Or even running one of the lines through a bucket of icy water...

THe only peltier cooler I find is the novatech ice probe, which will max out at 6-8 degrees of cooling for a 10 gal tank. I was hoping for a significantly higher max differential than that. For the level of cooling, I'm not going to replace my current set up, which is a controller + room fan.
