Koriala nano question

[aafjr2]

so i went into city pets today and noticed the k-nanos came in two levels... one pushed 240 gph while the other did 420 gph i think... soo which one would be better for my 12 gal nano.... im trying to get my equipment first.... so the 240 or 420? or 2 240's?

[aafjr2]

any suggestions?

Depends on what you want to keep. More than likely I would go with the more powerful one. I have a MP10 on my 28G and run it at about half speed which is roughly 800 - 900GPH so. I turn the water over about 30x an hour.

I have the 240 running on my 12gal nano and its perfect. My tank is mostly softies.

[aafjr2]

just softies like cichlidtx..... also on the 12 gal did you do the maxijet upgrade? i been reading up on how people say its better.. is it a hassle to change it, where can i find it?

[myjohnson]

I had a maxijet mod on my old nano 12g dx.

It was good flow but doesn't have the same coverage as a mp10...but then again what does.

[aafjr2]

where can i find it.... i would want to do that along with a k nano

[aafjr2]

i went along with the 240... traded my freshwater fish for it... now to get rid of the tank

I'm running a Maxijet 1200 for my return and works great. I bought online. Here's link to my build on Marsh.

how was it to change out the pump? was it just disconnect tube... change pump, connect and turn on? also where can i find that white crate thing?

I assume you are talking about light diffusers. You can get that at home depot or lowes in the light department.

oh, i didnt know thats what they were.. i didnt want to place he rocks directly on the glass, and was wondering wht it was.... thanks

[Darbex]

I wouldnt worry about it for that size tank. You wont have enough rocks to cause a problem. I dont have it in my tank and I have roughly 40lbs of rocks

[aafjr2]

oh all righty thenn..... would it be okay to put it rocks first and then sand? or other way around?

[RocketSurgeon]

You want to put the rocks first, then sand. Reason being, is if you get a fish that likes to dig, it will dig all the sand out from under the rocks, and you have a massive rock slide that falls into the glass and breaks it. You want the bottom rocks secure. I have heard individuals setting rocks on pvc pipe so that they are not buried by the sand. This will raise the rock the height you cut the pvc. This way, 20 to 30 % of your rock is not under sand. It appears the rocks are on top of the sand, yet they are still stable in case fish try to dig out from under them.
