I have a 120 DT, fish only. It's been running for 30 years using under-gravel filtration. Things have changed and I have a new cabinet under it now with space for a sump. I'd like to have the benifit of addtional water for stability, the additional filtering and a protien skimmer. It'd be good for my current tenants and might allow me to add a couple more.
I can't find a HOB overflow with the 3 drain pipe set-up and am hearing some scary stories about the siphon type boxes causing flooding if they loose the siphon.
I don't think I can use the sump as my only filtration so I'm gonna keep the under gravel going as well.
Is a sump at this point worth it and how best to go about it without drilling the tank!
TIA
