Thank you for your reply.
Well you guys are experienced. Since I'm one step from ordering the grass for the aquarium I really have to think about the plumbing before actually buying anything.
So 4 holes are not needed, and having 2 seperate systems is going to be very difficult.And I need to match the overflow to the pump output at 4'head.Correct?
How can I measure the overflow?
I'm going to have buckleheads and strainers.But I'm not sure what size to choose.Flow is going to be affected by the size of the hole right?
If I m reading right you suggest they are 1 inche in diameter?
(sorry but where I live we use metrics and the single and double quotes of the inches confuse me)
It would be nice if someone with a 100 gallons tank and drilled holes could give some advice.
As for the sump and refugium this is my understanding of your suggestion:
This way I can avoid a 90 degrees turn since I can place the pump upright from the beggining.I'll probably have only one 90 degrees turn when the plumbing makes a turn to get in the main tank.(that will make it a 5 feet head?)
I really have no idea on what the flow to the sump/refugium will be so I can't choose a pump right now.
This is the site I'm going to order most of the equipment.Its the plumbing parts section. http://www.marinedepot.com/ps_Aquari...strainers.html
If you can give me some suggestions on buckleheads and what flow to expect then I can make my choice on the right pump!
And how can I control the flow to and from the sump system. The main goal is to be sure that the sump wont overflow nor drain.(drain will kill the pump right?Can I use valves to control the flow from and to the sump//refugium? How will a valve, that reduces the flow from the return, affect the temperature of the water?
Thanks a lot!
PS: As for the bioballs I know they're not necessary but I guess as a newbie I'm going to have bubbles problem and since I 'll have to put something to stop those bubbles as might as well put bioballs.The bioballs I have in mind is a package with foam, carbon and ceramics. I've read that the second chanber is for chemical media.Do I need chemical media, other than carbon? I've also read that bioballs will collect debrites and increase nitrites, but I plan on cleaning them every other week along with the water changes.Feel free to make any suggestions!
