powerheads for a 75

[otterpop510]

two seios should be fine. for the money they are more than worth it if you don't have hundreds for the tunze, better to spend all that extra cash your saving on a good skimmer or other equipment.. google the seio or search on rc, most people recommend, not like the older rio products. no problems with mine, quiet and reliable. my 820 seio in my 75 tank works great, good spread on flow and not too strong to make a sandstorm, i'm aiming to get one or two more soon. i like them more than the mj on wavemakers, my tank seems to like them too.

 

[LekicINC]

i think ill try the seios and then maybe upgrade to tunze

 

[Jeremy B.]

You can always stick the Seio's on a timer as well to shut down for an hour or two randomly through out the day to make the water flow a little more random. Just a thought....

 

[zanemoseley]

I suppose they're ok on a timer but try to avoid the constant swithing of a wavemaker since I heard over time it will demagnetize the impeller.

I mistakingly purchased a Seio 2600 online. I meant to get the 1500, but mis-clicked and got the 2600.

That thing is HUGE. I went ahead and put it in my 75 and was able to hide it with some aquascaping.

It is pretty awesome, although it did raise my tank temp 2-3 degrees and I think it is a power hog. But my rock looks super clean, and my fish seem to like swimming in the stream.

My wife was afraid for the poor little chromis

I also am running three maxijet 900s under and behind the rocks to keep the corners clean.

 

[zanemoseley]

A 2-3 degree increase just from a large seio seems odd, they only take 52 watts of power in the first place. Even if it gave off 25% of that to heat its still just like having a 13w heater going all the time which isn't much in a 75 gallon.

 

[skidmarks]

You may be right, the heat may not be from the powerhead, as I also changed the lights on my fuge. That may be more the culprit. Either way I love that powerhead and wouldn't change it!

 

[Ralistin]

WOW! Almost have to drop 250 and change to get a Tunze 6000 streamer? That thing better spit out free coral frags for that price! :eek1:

Exactily... SPS are the only specimen in an aquarium that really NEEDS alternating high flow. Sure LPS probably like it but 99% of the time it isn't manditory. I'm not saying you shouldn't have any circulation on a LPS/softie tank but its not as much a requirement as a SPS tank. I've seen 120 gallon tanks with just a small/moderate return and 2 or 3 maxijets with phenomenal LPS and softies.

this is simply not true, have you been to a reef?

there are larger polyped stony corals in high flow areas, and there are larger polped stony corals in low flow areas.

there are soft corals in high flow areas and there are soft corals in low flow areas.

there are smaller polped stony corals in high flow areas and there are smaller polped stony corals in low flow areas.

there is no magical line that seperates them.

 

[zanemoseley]

I'm not saying some softies and LPS don't like some nice flow but overall softies and LPS don't NEED high flow to be healthy.

 

[Craig Lambert]

I posed the question about lps and softies on tunze forum as I'm looking for the ideal flow for my 75G. I was gun shy about the amount of flow provided by the tunze streams since the tank has good sized frogspawn, anchor, and hammer corals that are doing nicely and this was his response:

I don't recommend Streams for the Euphyllia type corals. Your tank is not very large and it will be hard to place them so they are not overwhelmed by flow.

Just something to keep in mind if your tank is on the small side with softies and lps.

what mm polyp size needs high flow? what flow does medium sized polyp stony corals need- medium flow? are you suggesting a direct relationship between polyp size and preferred flow?

like i said before, there are some stony corals (varying polyp size) and soft corals that absolutily need high overall flow rates. there are others that don't like it. there is no relationship between polyp size and flow preference.

and yes euphyllia in general is one of those that likes just enough flow to make their polyps bounce in the current.

Polyp size has nothing to do with flow requirements.

 

[zanemoseley]

No offense Sanfernando but if you truely believe that then you have not had much experience with reef tanks. Go to the SPS forum and ask them in general if SPS need more flow than LPS. Most 100% will say yes. I realize there is no distinct line between high flow corals and low flow coral but all I'm saying is that flow is a critical factor in the health of SPS where as in LPS they are in general much more forgiving to lower flow.

 

[Sanfernando]

zanemoseley you have not answered the above questions.

No offense to you but i don't consider the "sps forum" a knowledgeable source of information. I consider having the proper amount of flow a critical factor for all corals, not just "sps". Some corals need high flow, some prefer lower flow. polyp size is irrelevant.

 

[Sanfernando]

By the way, have you ever dived in an indo pacific lagoon where a lot of your "sps" corals in this hobby are collected from?

 

[zanemoseley]

Could you post some pictures of your tanks? I'd be interested if you actually have any successful tanks and what they look like. I'm not saying you don't but I'm starting to question your reef experience and knowledge especially when you question the SPS forum which is full of knowledgable people that continue to push the limit of what can be done with coral in captivity. Also I have visited a couple caribbean reefs however no pacific ones. If you like I can post an updated picture of my 2 year old SPS tank that is almost grown entirely out of captive raised frags.

 

[Sanfernando]

I am not saying you dont have a succesful reef tank. I am sure
your tank is quite beatiful, can you post some pics, I love to see different peoples tanks): I just don't like to make generalizations on which coral need high or low flow. Which caribbean reefs have you been too? It is always nice to see pics of tanks that are grown out from frags. Happy reefing.

 

[Sanfernando]

also, what do you mean by people on the sps forum that continue to push the limit to what can be done in captivity? what limits have they pushed? Is this the same people that try to identify different acros by out of focus pics?

 

[zanemoseley]

Thats an ok pic. 90% of the stuff is from captive frags. I've been to the bahamas and cozumel where I saw 2 reefs (palancar and cordova). The people in the sps forum continue to pioneer new methods of keeping picky corals and continue to be successful with them. Yes they also try and ID from bad pics often but thats just what people ask for and they give it their best shot. Perhaps your criticism would carry a bit more weight if you actually had some reefing experience. Diving is a whole other thing, its good you know a lot about natural reefs but in the reefkeeping hobby it will only take you so far.
