20000K bulb & tunze 6060

[Plenum]

Hi

I am considering changing the 10000K bulbs on my MH to 20000K for 150W. Wats a good brand and where can I get it. Price need to be reasonable.

Also will a tunze 6060 be too much for a 4X1.5X2 (IOS)?

hv u considered 14kk? phoenix bulbs r not that bad. 20kk might wanna consider BLV....... quite good IMHO. tunze 6060 might not be enuff for ur tank size.

Haven't heard many people using 14000K. Now gotta research on this. Haven't seen the effects of it. Would it be yellowish cos I wanna change my 10000K is due to this.

One tunze not enough? Currently I have return from IOS about 4000l/hr, one eden 1000l/hr, and one 1000l/hr ph giving 6000l/hr = about 20 times. If I add the tunze it would be 40 times.

I was afraid that that might stir up too much sand. I've got a mixed reef but mostly zoos, hammers, and one acro. Was hoping to replace the eden and ph with the tunze giving 10000l/hr = about 30 plus times. Thought that would be sufficient.

Anyway, I'm not too good at plaing the flows as well as the sand gets stirred up real bad. Do u place your flows near to the surface of the water? I placed one ph halfway down the tank to give more flow to the substrate to clear the diatom but its hard to get the right angle.

14k light, if u see it u will love it..

it's not too blue and not too white... somewhere in the mid..

and u can be assure no sign of yellowish...

as for your return pump.. have u cal head lost yet.. cause after head lost and heigh it may not be 4000l/h

if u add in tunze 6080 u can take out all your ph.. and save cost too..

Plenum,

You can put the tunze6060 hiding among LRs, in the middle height of the tank, and facing 45° upward, facing the return pipe.

This is to reduce stirring up your sand bed and the current flow crashes with the return pipe flow to create natural wave.

do a search for pheonix bulbs, u shld be able to get a review on it by one of the senior reefer here. u'll be surprised with the results. i used to hv a mixed reef too. read my signature. juz imagine my turnover rate. the trick is how u position ur PH.
