My 75 Gallon Build...

[kwest]

well...took about 2 or so hours to do it all last night. but we got everything transferred from my old tank to the new, and the new one complelty setup...And damn it looks incredible. Ill be takikng pics tonight or most likely tomorrow cuz i work all day today unfortunetly..

Cant wait to see it!!

[kwest]

Well here are the elongated pics..haha hope everyone likes the setup. Im am pretty satisified with it, just a few things have to be redone or organized i guess you can say. and then of course not using the glasstop and replacing with the mesh top ill be making this week...Let me know of any pointers yal have for me. thanks again.












Ill post pics of the sump and stuff in a bit, im bout to eat dinner. Also check out the awesome live rock i got. It already had all kinds of mushrooms and a cool green mushroom polyp, and also a couple small polyps ill have to take some close ups of, that and a finger leather coral!

Hey Kwest,
New tank is lovely ;D. Look forward to seeing it mature.

Looks awesome!! once again I'm jealous ::)

[kwest]

Thanks for all the compliments guys. I love my new setup. Tomorrow ill be constructing my new top. Get rid of this ugly glass top, and hopefully i can successfully rearrange my power heads, because i can't seem to get a good spot with them. The koralia 2 is good, but my 4 keeps blowing sand everywhere. I moved it last night and was satisified with it, but woke up this morning with sand over my entire live rock on the bottom with my mushrooms on them. So i just turned that one off for the night and wil try to exchange it tomorrow for a 3. Seems like the 4 is just too powerful for my tank.

great job!! nice sump...

this is kind of late as i havent seen the beginning of your posts but i also have the nova extreme with the 8 bulbs but on a 125 tank. works good but was looking at changing out some of the lites so maybe can have corals that require higher lighting..

Seems like the 4 is just too powerful for my tank.

I say no such thing. You just aren't using it correctly. I have seen a 90G cube with oolithic sand (that is basically dust to you and I) and a wavemaker which had maybe 20-30x turnover per hour (I can almost guarantee that is more than you are working with). I am talking some raging current in the tank. The sand moved over the course of the day, but wasn't kicked up at all. Try moving it around, pointing it at the tank to deflect the force and create turbulent flow, putting some rocks to bounce the current off, something...

You rarely want strong laminar flow in your tank, which is what pumps and powerheads generate. Reef dwelling organisms are exposed to turbulent, chaotic wave motion and currents, and that turbulence is what the majority of your livestock will thrive in (unless you decide to start killing off sea fans, which some people seem to be into). Keep playing with it. More flow is most always better, especially in that 75G. You will have all sorts of "dead spots" when you get to aquascaping.

more flow is good. In my 46 gallon i have :

2 koralia K3's (850 gph ea)
2 koralia nanos (240 gph ea)
2 returns from sump from a quiet one 3000  into a 3/4" SQWD which alternates flow betwen the two outlets. after head loss and loss from the sqwd its about 540 gph

that gives me about 2700 gph flow in a 46 gallon tank.

[RandyFolds]

I have a hard time believing that the koralias actually push what they claim. Maybe I just can't gauge it because it isn't getting crammed through some tiny pipe, but their flow is just so turbulent and diffuse that I don't think it measures the same way. A maxi-jet 600 will plaster something against the glass of my 30G, but a Koralia 2 will barely even be felt across those twenty inches. That is why I say that there is definitely a way to correct the flow of that Koralia 4 for a 75G.

I toss on one of the flow directors when I need some current further away, like when I break off chunks of montipora while messing around in the tank, but my return and two Koralia 1s with the open front keep my 30G moving everywhere.

[Bergy]

i dont doubt they korallias 'push' what they claim.

but i do believe they are measuring evertying..  with thier open desing and water being 'moved' all around the pump, not just the output, it can be easy to come up with thier numbers.

but, your comment contradicts your earlier comment about them being 'laminar'

[RandyFolds]

They still kick out laminar flow, it is just a way more diffuse and wider stream, and is therefore broken apart by obstacles and other flow in the tank way easier than a stream of water out of a 3/8" opening. It also really makes a big difference if you have the little directional thing snapped on. If you leave it off, it seems like it blows in about a 60 degree swath.
