Ok so planning stage of a 4" bubbler. I have some of macs 2" caps for my plates and I am going to do a 6" inline thumper. With the thumper can I just use the two inch cap dimensions and increase the bath to 120-130mm. Also would there be any benefit to running two of them on the 6" plate ? The standard plates will just use a single 2" cap. Plan on running 2400-3600w. will take some experimenting to get it where I want but these are numbers I see on here all the time.
Also from a safety perspective of puking safely. Do you fellas think v notchs or slits are the way to go in the bottom of the cap. Cheers
