ReefWave 25 letting me down

[lx_Reef]

Iv had the ReefWave for about a month now and it been nothing but a headache, anything pretty much under 20% leave the pump on constant mode , making all the modes useless. Anyone one else on the same page. Do I maybe have a defective product or does it only work at hight flow ?

I don’t think your pump is defective in any way. DC pumps generally have a minimum flow setting at around 20%. Any setting lower and it will still run at around 20%. So if your max setting is at 20% there is no room for fluctuation at a variable speed settings as it’s gonna just sit at that same 20%. Is there anyway that you can bump up your max setting to around 50%? That way, at a variable speed setting, it will fluctuate between 20% and 50%.
