Is it worth it to have 2 holes drilled in a tank for a closed loop, what do people like these over powerheads. Please share any and all thoughts on the advantages/disadvantages. I can understand they are less visible than a powerhead and there is a risk of flooding but what else?
If you want to plug the holes temporarily, how do you plug them?
