hi all, i bought a Big reef set up a while back that was a smidge to big for my rental house;Facepalm lol. anyhow I'm building a 120 mixed reef setup now and have a huge skimmer that i need to plumb i plan on using a MD-100RLT on the skimmer not sure if it will be powerful enough to circulate the tank as well, i mite need a dedicated pump for that any thoughts and opinions are welcome. the skimmer also has a drilled pvc tube that is plumbed in from the side of the bottom box about 3/4 the way up the bottom box and and goes just above the bottem of the collection cup. i haven't been able to find anything on this has anyone seen this drilled pvc tube before? if anyone has a pdf of the manule for the etss 1400 that would be awsome if they could pass that on.
