powerheads for a 75

You seemed to have racked up quite a bit of experience in only 2 years.

We will have to disagree on a few things. One, just because a tank has tunze streams, doesn't mean that a tank has "high" flow conditions, similar to that of reef crest.

Second, do you honestly believe that some of the bottlebrush growth forms of Acroporas require the same flow as that of corymbose growth forms? What about some of the Favites that grow in strong surge, do they not need this in captivity because they have a larger polyp size?

Third, can you be more specific about which sps forum regulars have pushed the envelope and what they have done? The forum is just a breeding ground for regurgitated misinformation, speculation, generalities, and self proclaimed experts.
 
SeanT, MiddletonMark,Steveweast and Reefermac are a few to start with, they are very knowledgable on SPS corals and all corals for that matter.
 
Yeah I'm getting kinda sick of San bashing a hobby he is new to. He sounds like someone who has read too many coral books while never actually had a tank.
 
Actually i've been in this hobby five times as long as you have. You have become very good at regurgitating misinformation in the short time you've been around. I like how you avoid all questions poised to you, and cite an online forum as a reference. I'm sorry i've read to many "coral books" for your likeing.
 
skid (and others :) ),

I have been using lots of maxi 900s in different tanks. They work fine for what I have. I will be putting up some larger displays though and I would like to get some seos.
The tank will be 3 side viewable (2 long sides) 2.5' X 4' X ~ 15".
What would you do with this given your current experience.

Currently I am leaning for 2 1500 and aim them in different directions to wrap around the tank.
 
San: When you get a tank then maybe I'll start listening more to what you have to say. You say you've been in reefkeeping 5X as long as me but you have no tank. You are obviously well versed in traditional/scientific/natural coral information however I still doubt your knowledge of the in's and outs of a reef tank. I have shown you what my knowledge has allowed me to grow, while its not the best tank ever I feel its a moderately successful and nice looking one. You will be greeted with open arms if you accept the knowledge everyone on this board has to share instead of fighting it and disagreeing with anything people say.

Again, you are going to find differences what scientific or even advanced aquarium coral books say and what is the general consensus of knowledge amongst the advanced hobbiest is. For instance I know there is no real distinction between LPS and SPS corals in biologist's minds however very often the generalization helps out the hobbiest because "IN GENERAL" SPS like more lighting and flow than LPS which can often tolerate and thrive in lower flow and lit tanks or regions in a tank.

After all this is a hobby and I treat it like one.
 
zan,
I like how you keep using the term "tolerate" as if it was our goal in reef aquariums to have the animals we keep tolerate the conditions we provide. If we can agree that there is no real biological division amoung differing polyp sizes, and that "sps", "lps" and soft coral are found in a wide range of different reef environments, than how can we formulate an effective general rule for water motion.

and yes I have a reef aquarium.

BTW I have seen the most benefits derived from the water flow provided by streams/waveboxes from different Sarcophyton sp. and Lobophytum sp. as far as polyp extension and growth are concerned.
 
How about some pics of your tank??

If you look above I said "tolerate and THRIVE". I'm not implying we should keep a coral in the minimum conditions for its survival. Many LPS do quite well in many conditions that a SPS wouldn't.

What is your theory as to why "LPS" can do quite well in many conditions that a "SPS" can't. Do you have any references. There must be some sort of anatomical difference between them as to why every, or at least the vast majority of species with smaller polyps do best in high water flow while those with larger do best in low flow. Why doesn't this actually occur in the wild?

Do you consider all tanks with tunze streams "High flow". It seems to me that none of the systems in our home aquariums come close to the water movement of the reef crest. As far as gph wise, it would take about 15-20 tunze 6100's in a 100 gallon tank to have a similar turnover.
 
Yeah I'm gettin kinda sick of constantly having to try and uphold concepts that are commonplace in reefkeeping to san. San, if you really feel compelled you can PM me to further discussion however my experience is limited to reef keeping in the home aquaria and cannot provide many "real world" examples. I will give you a tip for success on reefcentral and that is to simply openly listen to what others have to say. Your feedback is important however you seem extremely overly critical to commonly held beliefs in the reef aquaria hobby.
 
The problem is that people like yourself spread "commonly held BELIEFS" as facts even though they have no data, both in the field and in the aquaria to back them up. It is unfortunate that people commonly place corals with very different requirements in the same aquarium because they have a similar polyp size. Than they blame a dsb (or a number of other non-causative agents) when their tank starts to crash.

Sorry but I read enuff of your personal attacks in various post over the last few days. We are here to help not troll around rc stirring the pot and attacking people. 2.5 years ago you didn't know what type of flow you should have in your tank either.

heres a quote from you.

" I want to upgrade the current in my tank and was wondering what device is best for coral growth and health. I mainly have sps and the tank is a 90 gallon. Any ideas?"

another
"Well I had a bunch of powerheads but I had some electrical problems around where the tank was and they are irrepairable now. I was looking at getting Sea Swirls or something like the Tunze stream, does anyone have any experiences with either of these or other similar devices?"

Be gone!

Sanfernando,
The reason high flow helps SPS in our tanks is due to the polyp size and locations. A twig of SPS has polyps all the way around and that means the flow needs to hit all sides for the polyps to get the nutrients needed.

You wouldn't water one leaf on a tree and expect it flourish would you. Well you wouldn't want flow to just touch one side of the SPS either. High flow tends to swirl in our closed environments effectively getting flow to all the branches of the SPS corals and to all sides of each branch. Now thats not to say all SPS need high flow but alot do.

As far as LPS they are fleshier and high flow tends to peel the flesh...

Now there is no need for documentation to back that up...ITS COMMON SENSE.

:bum:
