Happy Memorial Day! Thank you to all of those that served and those that didn't come back! This gives me my freedom so I can surf R2R this morning and get advice/help. It doesn't go unnoticed. That was not political, just appreciative to the veterans and families out there. Let me start off my saying I just got back into saltwater in Jan after being out of it for 12 years. I' Here we go. The 24g AIO tank I set up in January was already full with coral so I needed to spread out. I'm currently building a SCA star fire 50g cube I purchased from another local reefer. Tank was leak tested came with sump and plumbing. I ordered a Vectra S2 at the other owner's recommendations. Wow, what a pump! Sand/live rock were added last night, tank was filled. I'm finding I'm having difficulty balancing the flow back into the sump. It is normal for a drop every 30 sec to come out the emergency? I haven't had a tank with a sump like a said, 12 years so I'm learning. This feel like a balancing act to get it right. I did add a bottle of Dr. Tim's for good measure as well. The loc lines were pointed down towards the sand last night, my rookies mistake so my sand got moved around and the tank did not clear at all overnight. Oops. I'm not sure how long it will take for the tank to clear. I used the fine oolite sand because that's easier on a goby. Any Ideas, thoughts are greatly appreciated. Thanks!
