Misinformed, dont think so. Where would you honestly put your money? In a hobby that already cost a bit to get into why short cut your equipment to save a buck? Just doesnt make sense.
That is true when it comes to some things but there are things you can save a buck on and still get quality products. Such as the filter and lighting they work the same way the more expensive options do. I said you are misinformed because you are under the opinion that using the Sunsun filter you are any more at risk of draining your entire tank then you are with an Eheim or other brand filter.
