Hang on overfllow box Yes or No

[El_fishman616]

I will be setting up a 90 gallon tank and haven't decide if I should drill the tank for a over flow or use a hang on overflow box I have. Need some advice pros and cons plz and thank you

If you can drill then do it. It's better in every way imo.

+1. Omg is it better! I will never go back to a HOB overflow again!

Hob is just another thing to worry about. Drill if u can

Drilled is better but if u can't ..hob are great I've never had any proublems with mine its been on my tank over a year as long as your return flow is matched with the overflow correctly they are proublem free...
