15 Reasons Why Current/Flow are Essential

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.
 
I didn't read thru all the posts here but all I would say is go for a dive or snorkel on a reef and check out the flow there, in my years of diving /snorkeling there is nearly always some degree of water movement,yes there are spots on the reef that have little or none but as a rule all water moves on the reef thru tidal movements and storms and reef inhabitants live where the water flow suits the species,so I do believe that water flow is a must in the home aquairium but how much may depend on what you have growing in your tank
 
True that, softy only, mixed or sps system would have minor to major deviations in type, amount and quality of flow. I guess the one constant we all deem to be true, is that current is indeed vital.

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.
 
Thanks for the tip Ryan,I've not heard of them but I will check them out ,and I think also that quality flow is better than quantity ,a never ending battle to perfect our tanks

I have a friend who used them and he seems to like them. Achieving flow, by any mean necessary. Thanks for sharing that mate.

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.

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

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:
 
Well... there are disagreements all over. Always!!!
It's important to keep the lovely conversation among us.
Kids and women could be present. :love1:
Besides that, the respect towards one another is what will keep us coming back to talk.
We have the option to PM stronger disagreements or complaints to the administrators...
There is no competition, or... shouldn't be!
Nobody is better than anybody here. Just different experiences.
Just a hobby!!

Let's cool down, right?


That said...

Great thread, my friend.
Certainly many of the points you've posted are important and could be appreciated by all of us.
Water motion in our tanks are just a fraction of many environments where our zoanthids are coming from. Good to understand about that!!
That will help many to maintain their reefs trouble free!
Thanks, Mucho!

Keep it alive!

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

Water motion in a reef tank is like the lights. You need to adapt the organisms, or better yet, understand their need to place them in the right spot.
For the zoas... most of them can be adapted to tolerate a laminar type of medium current. Some will do better than others... It depends where they come from or the type of metabolism they have. Slow adaptation is the key. Can't be tired of saying that...
Happy reefing!

Sorry for not being clear on that. Post #8 mentioned it might be better to just siphon out the slime. My comment was definitely not directed to you and was just saying that flow was the answer to my slime problem
 
Hey no problem. I also agree on your comment regarding the slime. Siphoning is reactive, preventing it is proactive.

Thanks for posting this Mucho. This forum is a great resource. On flow, I am about to start on a Zoa specific tank. Dimensions will be 24 long 12 wide and 15 high. The tank will be sumped and viewable on 3 sides (the back of the tank being 12x15). I was thinking about reusing a couple of my 6025s to provide flow down the length of the tank. Do you think this would be too much? Any advice gratefully received.
 
Hello, and thank you.


2 x 6025's on a 19 gallon tank, wow, might be too much. Maybe on a reverse cycle timer, but both running at the same time, might be too much. I have never owned the 6025's, but on a 12 " deep tank, it's gonna get chaotic in there. Maybe someone else who has used them can weigh in here. As long as the current gently wiggles the skirts and does not cause retraction, you're good to go.


I'm more concerned about you being in Tokyo. Things are kinda rough for you guys right now. How are you doing? Hang tough my friend. My thoughts and prayers are with you and Japan.
