I seemed to have solved the problem by adding a elbow to my siphon tube on the tank side. When it was straight any bubbles where able to head straight up the tube. The elbow seems to have alleviate this so far.
I also think I need a stronger pump as you said fish freak. Right now I only have 175 gph ph
for return. The OFB is small/used so I assume its probably rated somewhere around 300 gph
. As of now all I am really doing is expanding capacity a bit into a 30g from my main 75g and giving myself a place for the protein skimmer and some extra filtration.
Hopefully funds will become available to do the job right in the not so distant future but this is serving to get my feet wet....literally
Thank god for ceramic tile floors.
