20G to 75G Upgrade.

[Arawk408]

Hey Guys,

I finally got around to buying a 200G tank for my Arowana & Oscars that are currently housed in a 75G. I'm moving them tonight and want to start setting up this 75G tank for a reef tank!

Couple Questions

This is a 75G Top Fin Tank (So it has no pre-drilled holes for plumming)
My Question is how should I run filtration? I currently like the AIO System my 20G Reef tank has... Was thinking of using the Fijicube for 75Gs.. and silicone it inside the tank... but I really wanted to use a 20G High i have laying around for a sump but I have no plumming drilled and i'm scared to shatter my glass doing so... can I run plumming to a 20G tank and have a return pump with a hose going up and sitting on the rim (kind of like a cannister filter except run the hoses to a tank a) or should it be better to just use the AIO filter?

Drilling is not that hard. Search for videos.

Look into a 'ghost style' overflow box and drill the back glass.
Using 'over the top' return plumbing is perfectly acceptable.
Using a tall 20g tank will make it difficult to work under the tank. Better off looking for a 20g Long. Or better, the longest shallow tank that will fit in the stand

I know its not hard... Just that tear of breaking my tank
