The bulbs are 9" above the water, I've got a standard 90 reef ready tank.[quote/]
You should be able to keep lesser light demanding SPS in the top of your tank kinda like a crest line.
Thanks for those links, lots of good info there.
See now you have a book
Glad i could help.
I'm not going to drill my tank for the bean overflow. So where can you pick up gate valves locally? I think I'm going to totally redo the drain lines when I do the herbie.
Oak brook Ace Hardware is a local source for PVC gate valves up to 2" in Lakewood Wa. Not sure if any in Seattle carry them.
Wow I didn't realize the mini's put out that much flow, I'll look into them.
If that still isn't enough flow for you I would look into a used Eheim 1048 or 1050 etc. Usually pretty cheap used.
I would probably get at least 2 more and put them on the ends of the tank on either side. One high and one low. Combined with the ones in the corner you would have really nice flow patterns.
I already got the mag-18 and put it in place of the mag-12. I think the hose really needs to go, if I go with a herbie what flow rate would I see with a 1" bulkhead with maybe 8" of water over it? Would that be enough to balance the mag 18 at 6' head height?
Mag 18 at 6' is 1125 GPH. 1" PVC Gravity fed is 960. I would probably upgrade to 1.5 to be safe.
Thanks for answering these questions.
