Wishin' I Was Fishin'
Thanks once again Mucho for a fantastic resurrection and read. I agree with you %100... flow is a very impotant aspect of our reef tanks.
Has anyone tried hydor flos? They attached to most powerheads and rotate 360 degrees, creating a random water pattern when used with two or more powerheads. I have a local guy who grows, frags and sells loads of corals and his zoas are in a huge tank that have many of these and he has nothing but good things to say about them. You can pick them up for about 10 dollars. It will cut down on your flow RATE but the quality of that flow seems to outweigh the loss of actual gph.
Your thoughts?
ps I don't sell or advertise for these but I am considering getting two for my powerheads. I only have one zoa... but hope to have loads more.
Flow/current, via wavemakers, powerheads etc, serves many vital purposes.
1. Flow/current helps to keep live rock clean and clump free from settling detritus.
2. Aids in cleaning off polyps that slough off by means of external cleaning.
3. It carries much needed food/nutrient to corals.
4. Often greatly enhances skirt length over time if on the medium to higher end.
5. Helps to remove waste and slim when new arrivals are stressed.
6. Moves uneaten food off the reef to allow other inverts on the substrate easier access.
7. Helps with surface water movement via oxygen/gas exchange.
8. It helps with calcification.
9. Causes a natural water sway/movement, back and forth motion which is extremely natural.
10. Current reduces shaded areas allowing more light penetration.
11. Causes a glitter line affect for Metal Halide users. Glitter lines are often viewed/seen in the ocean and it is a means of punching light deeper into ones system. The fluctuation from light to dark is a very natural one.
12. Prevents coral bleaching.
13. Current helps with evaporative cooling of the tank.
14. Prevents stagnation.
15. Removes film from the water surface, which increases light efficiency
Will these apply to all conditions? I found my nuclear greens and some other zoas seems don't like current...but maybe I am wrong, just want to make sure before making adjustments again.
They probably don't like a lot of flow, but all corals like some current.
Picture corals as really, really lazy guys on couches. They'll eat if someone brings them food, otherwise they'll just soak up energy rays from the game on tv.
MUCHO,
Great thread. I agree with all of your benefits you listed. On my 125g, I have 2 MP40's and 2 koralia 4's to go along with my mag18 return. I get some great zoanthid growth and doesn't dose anything other than CA and Alk.
BTW, simply siphoning out slime from the tank does nothing but hide the problem. You need to figure out the issue that was causing the slime. For me, it happened to be more FLOW! :eek2:

Not sure if the second paragraph was directed to me or not, but where did I say anything contrary to the issue on slime that you spoke of above?
Thanks
