Question for all w/6ft 200gal and up tanks

Lance · #1 06-27-2009, 10:00 PM

I have a 225g (72x30wx24) mixed reef tank. For flow I have 2x MP40's, Korallia 4, MaxiJet 1200 with upgrade and Reeflo Barracuda return pump. All told, about 50x turnover. You could go with less flow if keeping only softies and LPS. For lighting, I would recommend a minimun of 3x250W MH with T5's for actinics; 3x400W MH would be better if keeping SPS. Mine has aprox. 5 watts per gallon which I consider too low for SPS, so I have all SPS high on the rockwork.
Hope this helps you a little.

Wowsers that's a lot of flow and lighting! I kind of figured it would take a fair bit once the tank is 6ft long. One thing I've found is that brighter lighting seems to 'urk' a lot of these corals but flow is different depending on the type. I have a 30gal that my MP20 runs on full out and its still super gentle. I tried to put a couple koralia's (can't remember the size)in the same tank and and it was way too turbulent. Diffused flow seems to be pretty important. By the way one of the LFS in Calgary is where I was told about the maintenence on the vortechs. Not sure if thats the case or not but I haven't had any issues with my MP 20 yet. I guess the other thing is I am fairly particular about having a tank that is close to silent as possible and the vortech is not exactly silent. I'm gonna have to assume that for would make a fair bit of noise. I wonder if the Tunze's are quieter?

Like someone mentioned previously, flow & lighting depends on what livestock you want to keep. SPS require the flow and light. LPS and softies, not so much.

I've used Tunze for years and can't say enough about them. The new Stream2's are a lot less bulky than the old Streams such that the whole argument about Vortechs being so much less conspicuous than Streams is no longer valid.

The Stream2s are now programmable via a USB connector and have an available battery backup.

I'd go Tunze or Vortech over any sort of a closed loop. A lot less plumbing and electricity to deal with.

I have a 60x24x24 SPS tank with a mag 12 for a return and 2x MP40W on 1/2 flow if that and 3x250's on lumenarc's reeflux 12K i have lots of light and the MP40's are great for the flow in the SPS tank

So 2 mp 40s are plenty in your tank on 1/2 flow? Doyou have lots of SPS? Because if thats enough for you in an SPS tank @ 1/2 power then that should be enough in a 6ft LPS/Softy tank. Either 2 MP 40s or two Tunze 6105s. I believe the vortech has a more diffused flow and they are smaller then the 6105s, but the 6105s put out more flow and have been proven over years to be reliable. Vortechs are still pretty new but seems like their second gen are fairly reliable. I'm still undecided on lighting though. T5s or Halides and T5s? Even though the tank is 28" deep I'm starting to think the t5s will be sufficient for the livestock I'm looking at. Just found this fixture. It has 14 t5s and looks pretty nice. http://www.aquariumspecialty.com/cat...oducts_id=1184

or maybe two of these although I do prefer the first fixture and right around the same cost too. http://www.aquariumspecialty.com/cat...roducts_id=473

IMO and IME that T-5's are not good for sps at depths of 24and greater I really dnt see them having the punch like MH i have had a 8 bulb on my tank a `120 gal and my sps had to be put at the top and the clam had to be pushed up to the top too. DOug can chime in here since he took care of my tank when i was in Afghanistan and saw the results. as for the flow i had the tunze's and the vortechs i really like my 40's for the size of the unit in a tank not much space they are slim and small not big and bulky. and yes they have alot of random movments on the unit for different flow. ya they are a bit more but hey aren't we in this for $$$$$$$ and wicked equipment and fish..

Like i say i have 3 250's on my tank the 2 outer lights are reeflux 12K and the middle one is a20 K reef optic bulb my lighting is started at
6AM- 11am morning light its a blue flood light.
11am -2PM actinic are on
2pm-9PM out side MH are on
4pm-7pm middle is on then its in reverse order...
so not all are on the whole day remember.
i could easily run 2 250s over the 5 ft tank. you could put 2 400's over your tank and have them high enough to light your tank too remember i have done that. i used to have a 280 gal tank with all softies and lps and ran 12 NO flouresants and 1 x400 in the middle too. and the lps loved it.

Don't overlook Oceans Motions 4 or 8 way. I am loving the 4 way in my tank. Properly set up, you can have a tank with no powerheads, just sump and closed loop.

Looking at the J&L website it says the Stream 2 pumps are non-controllable. Does the new 7096 controller allow you to control them or am I looking at the wrong pumps?

Both the 6105 and 6205 are Stream2s and are controllable. That's a typo on J&L's part. There's even a more powerful 6305 available.

The either the older 7095 or the new 7096 can control them, but the 7096 is the fancy-schmancy programmable one.
