Let's see your T5 SPS tanks!

No build thread yet but I am planning on doing it soon. I've been waiting till its actually something to show lol. Still young but it's going well so far.

Sweet tanks!

My tank has some growing up to do but here are some pictures

Very nice!

Bulb combo?

Beautiful tanks!

Very nice!

Bulb combo?

Thank you.

At that time I was using 2 x Giesemann Actinic 03s, 4 x ATI Blue Plus and 2 x ATI Coral Plus.

Wow what color!!! What bulb combo and what lighting schedual are you using

 

[Towner]

Nice pics! I never realized you could grow such nice SPS with t5's until my own tank started blowing up!

Coral+ and blue+ overdriven on an Ice cap ballast

8 1/2 hours a day...........all on and all off at the same time.

Any advantage/disadvantage to bulbs being over driven? Most of us use stock fixtures like ati and I am not sure if the ballast are over driven?

The obvious disadvantage is that the bulbs are overpowered, cutting into their duration of use pretty drastically. A good advantage though is that because of the already decent spread you get from a T5, overdriving them increases the PAR throughout the tank.

What about in terms of spectrum? Does it cause a shift?

Gorgeous tank Bill@IA

I don't know the true answer to this question. As an optics expert though, I would expect it to fluctuate a little, if not a medium amount. White bulbs that are overdriven tend to turn slightly yellowed, from my experience.

I have a 72" maristar 3x250w and 4x39w t5 system over my 150. Currently I have 3 20k bulbs and 4 tru actinics. I'm thinking of switching my t5s for 2 coral plus and 2 KZ fiji purple. Any thoughts?

Overdriving the bulbs produces a lot more par & as mentioned they only last about 6 months versus 12.

I get about 200 more par when measured with a par meter just under a single bulb vs an ATI ballast.

The blue+ bulbs will run a little less blue but it's almost un-noticable visually and my tank will look a tad brighter. I don't know if the secptrum is much different.

The overdriven bulbs/ballasts are making a slight resurgence because VHO is going away and people with deep tanks that were using VHO supplementing can transition to T5. If you haven't noticed Coralvue has re-introduced the 660 ballast and also the DIY kits are available.

Watched this video a few days ago about ATI bulbs. Found it really fascinating, especially the part about the actinic. What your guys' input?
