im planning on drilling my 29 and plumb it using the herbie method. I have looked into this method but am by no means an expert on it. i have a few questions i hope people will be able to answer for me.
I will be setting up a 29 gal
display with a 10 gal
sump so total water vol. should be around 35 gal
1. i am going to drill a return hole so i will now have a total of 3 holes in my tank?
2. what size bulkhead should i be using for a 29 gal
w. 10 sump? I was thinking about 300gph flow. (300gph too little?)
