Thanks chefzif, eros.
Color is a very big topic. I am still learning on how to bring the color out. I've tried different lighting, light bulb combination, different water parameters (pH, alkalinity), additives (amino acid HC, coral vitalizer, Zeospur2, Roti-feast, Oyster-feast, K-balance, B-balance, Zeospur macroelements, SPG...........). Be honest, I don't know! IME. I can see the color enhancement right after I 1. replace the new T5 lamps and 2. dosing with Zeospur2. |

Just get the par meter back. Here are the new par reading at 3 months old T5 lamps. Everything is the same. For easy comparison, I put par readings of 2 weeks old lamps and 3 months new readings next to each other.

I have some tank mishap a few days ago. The overnight power blackout costs me all the fishes, and the RTN forces me to trim or remove some of them. The tank looks a little bit out of shape. As you can see in the picture, no fish, no nemo blasts the sand. It is a low nutrition and peaceful tank now.

The new par readings still look good. Generally, it drops 5 to 10% in 3 months. No plan to lower the light fixture yet.

Hi kangym, can i ask you if the old bulbs you replaced had burnt or black look at the ends or tips and if the new ones have them too at the 3 month mark?, all my bulbs have black ends, maybe that is the sign for them to be changed, i sure wish i had a par meter, one more question did your friend that borrowed your par meter has t5 also, and how did he do on the readings?..

I know this thread isn't necessarily about cost of MH v. T5, but changing out 8 bulbs or more every 8 mos would sure seem to eat up that electric bill savings pretty quickly.
I'm glad I read this thread, I'm going to stick with MH for my new system. |

Good news is we might see some par readings of 8 x 80W ATI PM pretty soon. A local reef club member is running this fixture, and he promises to chime in. |

Sorry, it was not my intention to sidetrack the thread, but if the PAR value decreases so significantly as to require bulb replacement every 8 months, how are you saving so much money over MH? A 36" 8 bulb T5 fixture is consuming 312 watts, no? Shouldn't that be more expensive that a 250 watt halide? Then if you figure in the bulbs costs, doesnt the T5 just up even more in cost to run? Then if you figure in the that the MH fixture is cheaper... even more savings.
I'm not saying I am right, I am just curious where the savings is coming from. The only variable I can see is if you have to run a chiller, which luckily with a basement system in MN I don't have to do. |

Yes, you are correct. I am at central valley of CA. Two 400W MH heated up my system quickly and activated the chiller 2 to 3 times a day. My elec. bill reduced almost over 100 bucks every month after switched to T5. T5 or MH, it is just personal preference.
As for par, if you see the par reading of 10 months old bulbs. I will say it is still very impressive. It is even higher than many 250W MH reading. But I will never say one is better than the other. |

Yea, I wasn't trying to push a preferance either, just curious about how you were getting the cost savings. It seems that if you don't need a chiller, MH is in fact the cheaper alternative.

It's not all about cost. T5 and Halides are 2 very different beasts and both are great in their own way. The T5 vs Halide thing has been done to death, they are both winners. If we want to go into it in more detail we can start a separate thread, or post our opinion in one of the hundreds that have already been started...

The par readings are 100 to 200 less than those of 10x54W ATI PM at same 9 months old lamps. Only low light coral like monti plates, digi, pocilloporas or stylophoras grow pretty good in the tank. The color and growth of acroporas are dark and slow.
Is it about time to change the light bulbs? No, I think I am going to change the whole lighting. |

Finally, I got the par reading of 8x80W ATI PM from Ryan, a local reefer with great tank and setup. Thanks Ryan allowing me to visit his tank and check the par.

Wish there will be more people chime in. No matter what kind of T5 lighting you are running, if you have access of par meter, please share your reading with us.

Let's make a comparison of par reading between 8x39w and 8x80w same ATI PM fixture:
8x39W ATI PM hanging at 3' above water level 8x80W ATI PM hanging at 6' above water level |

If I have a 6 ft tank, I will go for one 80W fixture instead of two 39W fixtures. I spend less money and get more par with only one 80W fixture. Difference in total wattage: 8 x 39W x 2 =624W, 8 x 80W =640W.
