Let it FLOOOOWWWW

So in looking at PH's for the 75 I am setting up in May I am thinking that a Koralia 1 and 2 along with the Eheim 2215 should be fine for flow this will give me over 1100 GPH flow rate in the tank. Does this sound sufficient for a 75 or should I just go with 2 Koralia 2's and the Eheim?

really depends on what you want to keep. 1100gph isnt very much for a 75g. only 15x. your probably going to want at least two K2s in there at minimum

Re: Re: Let it FLOOOOWWWW

There will be a blue tang a copperband butterfly and some clowns and anemone and some other assorted corals. About 75-100 lbs of liverock. Snails and crabs also. Also a brittle star and sand sifter.

i would not put a tang in 75 gallon tank, especially with 100 lbs of rock in it...

just my 2 cents.

tangs need a lot of room to swim...

Well the kids want a Dory and I wasn't going to put one in the 31 gal so they are getting opne in the 75. Once it gets to big we will take it to the LFS and trade it for a small one again.

I've got 2 #2 Koralias in my 29 and its great for that size tank with open rock structure that spans most of the length of the tank. No problems with sand dredging like my PHs did. Given that, 1s and 2s may be a bit light for a 75. What do you plan to keep for corals, if any?

We plan on Frogspawn zoos and an open brain likeley and possibly some mushrooms. We may add more but not certain what at this point.

the higher flow should be fine for what you plan to keep. Just make sure the Euphylia (frogspawn) isn't getting blown around too much.

I was thinking about keeping it a bit lower in the tank and in that area having the PH pointed more upward so as to not fire it around to much. The tank dimentions are 48X18X21 and I will be running a Nova Extreme T5 HO system on it.

I would only use a koralia in a 75 for spot flow. You want a powerhead with much more controll especially if this is your first reef tank. A powerhead with a flow control knob and duckbill tip for dirrection control. Besides these are great for water changing as you can attatch a tube and drain and fill alot easier.
Proper flow is very important and the ill effects of low flow take time to show its effects.

I have 3x hk2 and 1 maxijet900 in my 75g, with about 400gph on my return pump after headloss. Im getting approx 32x tank volume in flow, with a good distribution.

not for nothing, and I'm not a member of the tang police, but the idea of buying a fish to return it and rebuy another one oft he same is kind of lame, dont you think? if you cant care for an animal it's whole life, dont try. my 2 cents.

I agree , its irresponsible reef keeping.

I'd aim for 25x turnover, maybe a bit more. I'm using two Tunze NanoStream 6045s on my 90g and love them -- combined with the return from the sump (~500-600gph) these two tiny pumps are providing all the flow I need (30x+) and they're very small. Tunzes have wide nozzles so that nothing gets blasted with direct flow, and aiming the two slightly upwards and towards each other & the front glass gives my tank loads of random flow.

I agree with the others about the hippo tang, it's not going to be happy in a 75g. How old are your kids? I have a 2" south seas damsel that's forever being called Dory -- little kids see blue and yellow and think Dory, if they're young enough it really doesn't need to be a tang to satisfy them

The kids are 11, 6, 5 and 7 months old and the older ones all know who and what Dory is.

Ah, too bad then. Any way that 75g can be upgraded to a longer tank? A hippo is likely to be quite stressed living in a 48" tank, even as a baby. They're much more of an open-water fish than most typical fish in the hobby, and tend to succumb to ich or HLLE if they're under stress. I'm not trying to upset you or judge you, just offer some advice so you and your family will have a positive experience.

No it was all I could do to get the 75 I wanted the 90 LOL. I am also strapped for space where the 75 will be going. It fits in length but going to the 90 would mean my stand could only be 18" tall even with the 75 the stand is only going to be 24" tall max. I have a height limit of about 50". With the tank @ 21" tall the lighting standing another 7.5" and the stand at 24" it actually puts me at 2 half inch over what my limits are but I can live with that.

I would go with the k4s. and go ahead and get a "Dori" if you want to.
I don't think its irresponsible to own a fish that you know you will have to return one day.... its a rent-a-fish. I mean come on how many TOTM have sailfin tangs in them? do you know how large a tank has to be to happily hold an adult sailfin?
know how big they get?

Ok ok so I will get the 4's LOL. As for the sailfin I think it said on liveaquaria that they will get up to a foot long or better if memory serves maybe it was 2 feet.
