Review on ISTA I H616 Inline External Heater by Rebecca Smith

The ISTA inline heater provides precise temperature control and is an excellent solution for those who want to keep their aquariums at a consistent temperature without relying on bulky in-tank heaters. Through trial and ERROR, i found that this heater was incredibly easy to install and maintain, and it helped maintain a consistent temperature in my tank. The only downside is that it requires an external pump, which can be an additional expense for some buyers .Overall, I highly recommend this product for novice and experienced aquarium owners alike..
