the seaclone discharges water from the top of the reaction chamber.. the absloute worst place that you would want it to discarge.. there is no way to adjust the water up further into the reacton chamber to get a good dry foam either.. the CCS collects the discarge water from the bottom (the best place to collect it) and you can adjust the water level all the way up to the cup if you wanted to (not exactly a good idea but at least you have the option if you know what I mean).. Its not that its a horrible product its just not very well designed and there is no way to modify it to collect the water at the bottom of the collection chamber without somehow completely sealing its output closed and lifting it up to the top of your tank to let the water out the bottom or the near bottom side.. this modification isnt done because of its complexty you might as well build a DIY
skimmer with all the work you did to get a medeocer skimmer to run well...
the preskimmer on the remora might be a pain but... it will increase the effecency of the skimmer if you can actually get it to stay put and you have a good constant water level.. in the main tank that would require an auto topoff in the sump it would mean being behind a good set of baffels too keep the water constantly the same level..
and yes.. I agree that a skimmer would help.. a good one such as the CCS 125 would help alot.
