SEIO 620 flow?

[avshockey311]

I just ordered 2 SEIO 620s for my 90 gallon. Is this going to be too much? I am going to put the 620s on the end and have a MJ 900 in the middle. The only real concern I have is my Frogspawn. As you can see in the picture where it is. Do you think I am going to have problems?

I cant see any problems at all, I have 2x620's in my 70g, and to be honest I wish I went for the 820's now.

I'm to new to know what is enough flow.. but I have a SEIO 820 in my 30 gal and I was also going to add a maxi jet to get some additional flow.

The SEIO 820 is nice but dont leave it in the default config take it appart much better flow I waited 2 monthes to do it and now I wish I had done it all along.

I have an 820 and 3 maxxijet 1200's in my 55g. I think you will be just fine. Remember you can adjust the flow.

I would go with 820's. The 620's don't provide much flow due to how widely dispersed the powehead moves water vs a MJ. I run two 820's (out of the encasement as ducati sites above) on a 75G.

I would return them and get the 1100s. The 620s don't move the water around much. The 630s and 820 are best for tanks <24''

I find twin 2 820's along with my retun (400gph measured) about all my 75G tank can handle since it has a dsb. If you run them outof the case they move lots more water. To much flow with a dsb and you have a small contant sandstorm.

I have 2 1500's in my 90. I had them in a 36" 70 gallon tank until a couple weeks ago. In that tank I also had xenia, anthelia, a hammer, etc. and all did just fine.

Holy Murshrooms Mania! NICE

That does look really cool. I can't say I've ever seen a mushroom tank like that. Your own unique niche of the reef.

Exactly! You do very well with mushrooms! As for SEIOs, I've ordered some for my 180, but have yet to set them up. I'll let you know once they're up and running.

Did you look into the maxi jet mods? There are mods that up the flowrate on the mjs.
