One thing about gravity feeding the skimmer is that I had to choke off my return pump to match the skimmer's capacity. I thought that would cure my microbubbles aswell but it didn't. Redoing the return pump's connections has been on my list for months.<a href=showthread.php?s=&postid=7190586#post7190586 target=_blank>Originally posted</a> by Hop
Hmmm... Somehow I really messed up the headloss calc when I was planning mine. I expected the sequence to be the right pump, but found out that I was way over powered. I bet I was pumping 1000gph through a T, right back into the sump as it was too much for the drains in the overflow to handle. Now with running the blueline, I don't have a T going back to the sump at all... and it fixed my micro bubble issue to boot No more filter socks!
My problem is lack of choice. It's either that or shelling out $500 on sand. In fact I don't even want to pay $50 for sand. If I sieve the dry sand and then rinse it really well I'm hoping it would be okay. But I'm widely open to advice on this subject.<a href=showthread.php?s=&postid=7190588#post7190588 target=_blank>Originally posted</a> by jnarowe
true, but you could get some good stuff in live sand. (as well as some bad stuff) But sand off the beach is bound to have a variety of pollutants I would think. Maybe you should, if you haven't already, do some research into that.
I know with my planted tank I did several "no-nos" like I used sand and rocks from the stream on our property, and I also used worm castings in a lower layer of the substrate. Most "pros" would tell you not to even think about that but I have one of the nicest natural FW Planted tanks around.
