A+++ Aquarium, 5 stars!! Love it, great work. :)

You said you had metal halide before. How long do you implement(use) the t-5 for now total time? I want to be sure its been long term, and not somthing recent.

Do the hard corals appear to grow slower without metal halide?

Thanks box :)
 
@ boxfishpooalot

I implemented the pure T5 illumination 12 months ago.
I was inspired of the long time's experience of Bernd Mohr.
Here some pictures from his tank.

Bernd has a pure T5 illumination since 5 years and obtains a good growth and beautiful coloring with that. This tank shows the T5 potential . the growth is considerably stronger than under MH.

what is the power efficiency of T-5's compared to M/H?:confused: :hmm1:
 
Wooow Iwan, you have one stunning tank, congratulations. Amazing colors!!!
I am curious about three things.
- Everything looks allright in your tank. Why do you want to add 2 more 80 watts bulbs? Do you think that your present ilimunation isn't strong enough or you are expecting a better growth and better coloration after adding the new bulbs?

- Your tank is 60 cm high and you have some SPS corals close to the bottom. Do you think that your curent lighting will be good enough for soft corals, mushrooms and LPS corals that need lower light than SPS's if they are kept close to the bottom - lower 10-30 cm- in a 70-80 cm high tank? May T 5 HO's provide enough penetration up to 70 cm depth for these guys?

- I saw the pictures of some SPS tanks running with zeovit. One of them was a stunning Italian tank running with only 10 K MH's without actinics. Despite that actinic bulbs effect SPS coloration alot even when they are used with 20 K bulbs the coloration in that tank without actinics was amazing. It is obvious that low or zero nutrient levels increase SPS coloration and growth alot. But as far as i know zeovit is kind of expensive. Nearly a year ago wodka method was discussed in a topic. Wodka method had some points that needed special attention and any failure at these points may cause a crash i think. Are there any points for the bact method that need special attention and may cause a crash because of failure -such as a big protein skimmer, external feeding, dosing etc? Is it an economic way to go or it is relatively cheaper than zeovit? How much do you spend for that bact stuff and how long you can go with it?

Thanks
 
@ Aquavidis

Thanks a lot.

The old illumination for certain wasn't bad. I have 160 watts more at the new one. The new technology in addition brings 15-20 % more light again. I expect better colors through this again. Light is one of the most important factors for colored corals.

This isn't a problem! SPS for certain won't achieve the most beautiful colors at a depth of 70 cm. However, soft corals and many LPSs are provided with light perfectly.

The bacteria method become used also at Zeovit. As an addition you still filter about Zeolithe. The bacteria and the food are similar at the two methods. The pure bacterium method needs a little more time till the positive effects are provable. At Zeovit is the danger that changes arise too fast insists. Reagieren.Wie can on this at every method only with difficulty, the bacterium method also should be used with the necessary portion of patience for corals.
The price for my bacteria method lies with my pelvis approximately at € 6 per week. I in addition put even further ingredients into the water (plankton, trace elements ...)
 
I was looking at what appears to be a birdsnest coral in your tank

Will this guy color up or will it stay that color?

The reason I ask is that I bought a similar coral thinking that it was just browned out and would eventually color up to either pink or green. The coral has grown considerably but has not yet begun to color up. I too am running T5's.

BTW your tank is astounding.
 
This is a variant of the seriatopora hystrix with missing color competence. this means the coral is missing the genetic qualities to train colors. The coral trains pale yellow till brown colors in dependence of the available nutrients. I also have the pink color variant.

I am not following you on this.

You are saying that there is a pale yellow variant? I have only seen green and pink.

I was hoping that mine would color up pink.
 
I bet mine is a cream colored one too.

I thought mine was just bleaching.

I really wanted a pink one. Yours is extremely nice.
