What size Korilia

[m_wonnacott]

Ok so we have changed the planed size of the tank we are going to have custom built we were going to be going with a standard 75 but now it looks like we are going with a 40"x24"d x 20"h eurobraced. Originally for the 75 we were looking at 2 Korilia 3 for flow plus the return but now I am wondering if I should go with the K4 instead? Whats everyones thoughts the tank will be softies and lps with the posibility of adding a monti cap as the only SPS in the tank.

I think it's really difficult sometimes for people to recommend pump sizes based solely on tank dimensions. Without seeing the entire setup with the live rock, coral placement, etc. there are simply too many variables to overcome with just guesswork. There are calculations based on GPH flow for certain size tanks, but that usually refers to sump/refugium flow.

For what it's worth, in my opinion it's actually more important to balance/regulate the flow than it is to worry about the GPH amount. I would prefer at least two water movement devices with the return rather than one large one. I say stick with the two Koralia 3's - that should be more than adequate. Those 4's can be harsh

ok sounds good though i am sorta looking at the tunze now as well since they are smaller and use less power

I have two of the Korilia 4s in my 120 gallon, and the flow is still pretty intense... I have a feeling they would devastate a 75 gallon.

 

[m_wonnacott]

hmm good to know looks like it will be the k3s or one of the tunze

I have a K4 and K2 in my 30 long that is mostly LPS and softies. The only SPS now is monti caps. There are a few areas of high flow that some of my corals would not like but plenty of places they love.

I have 2 Koralia #4's and 1 Koralia #5 in my 75

I've got 2 K4s on opposite ends in my 55g now. Fish seem to love playing in the current. I probably would be fine with 2 K3s too. I don't have any corals yet so don't know if I'll have to redirect them but for now all the inhabitants are doing good. I also have a gravel bottom and not a sand bottom so don't know if that would make a difference either in potential sandstorm.

As long as you bank the flow off the sides it seems to help. Just don't point the flow directly toward the coral. I have always had bad experiences with corals being hit by DIRECT flow.

I also have a friend with a 55 that has 2 K4's. All the fish enjoy the flow in his tank.

Thanks for the tip. If at all possible a pic of his setup or yours would be awesome. I'll probably start off with a RBTA first in about a month and let it settle in for another month to find a home before adding any LPS and softies.

I have a 65 (36") and have 2 K4's, it works well and I am actually thinking of adding a third.

 

[jenglish]

I also don't use the flow concentrator on either of mine.

 

[am3gross]

vortechs baby! i love mine!!!!! hate the price thou....

 

[Anemone0524]

had 2 k4's and 2 k3's in my 90.

bought 1 Vortech MP40.

All the Koralia's are inactive now. 1 Vortech does the work of 4 Koralias.

2 Koralia #4's in a 65g. Still not enough. Looking for an MP40w...
Welcome to the wonderful world of flow. Even with this amount, we cannot simulate the amount of water going over a reef.

The idea is to get a lot of flow, without the pressure. (No water drills).

I use 2 K4's and 2 K2's in my 72...
It's enough movement, but I wouldn't say to much. A factor more important than gph is randomness. Koralias tend to have a steady flow that doesn't change much, so its better to use multiples so the flow patterns can intersect. Higher end pumps do a better job at delivery a more random flow, and the new controllable Koralias will do the same, but they are just as much $ as higher end powerheads.

I'm gonna tag along on this one. I'd like to hear some opinions on using only 1 mp40 in a 75?

 

[Veosk]

Its diffucult to give and answer. The more flow the better of course. I know w/ my tanks that I needed to move the locations and positions of the powerheads so everyone was happy.

Wow. Speaks a lot to the way flow can be vastly different in tanks. I have mine banking off the glass, and then into each other. I still have problems with some corals being litterally ripped off the rocks by the flow.
