Too much light on a nano?

If you look at LED, an ai nano would fit the bill perfectly and can be dimmed to light acclimate corals.

There's been an important point made here by two knowledgeable people which has quickly been discarded.

T5's will grow SPS. If you couldn't sustain SPS, your light wasn't your issue. Most likely, it's either an issue of flow or, more importantly, water parameters.

I say this, because unless you fix the underlying issue, it won't matter what kind of light you use.

 

I wasn't discarding the advice. We were talking about 2 different tanks. One is my 40g breeder and the other is a proposed nano tank using a 16g bow I already own. I'm simply concerned with what lighting would be most cost effective and be condusive to growing sps which I am having trouble growing in my 40. I really just like to get an opinion on lighting. I want to use MH but I'm worried about the heating factor. I'm open to trying led but a lot of modular led stuff goes over my head the preassempled fixtures (like marineland doublebrights are WAY out of my price range).

If you really want to dissect the problems with my other tank go ahead: 40g breeder, 50lbs play sand, 50lbs live rock, coralife superskimmer 65, 1400gph of flow in a crisscross pattern, 10 hour photoperiod from 4 Hot5s (2 south pacific sunlight 14k and 2 zoomed actinics, 156w total), nitrate 0, nitrites 0, ammonia 0, calcium 480, kH 11, pH 8.4, phospate 0.25. The tank is 4 months old.

 

Well, being an LED user (DIY'd CREEs) for over a year and growing SPS like mad, I'd never use a halide again. If you're not the DIY type and you need to do something assembled, an Aqua Illuminations Nano would suit you nicely (on a 16g). And if marineland doublebrights are your LFS experience with LED, no wonder they told you what they did. Because those won't sustain ANY corals.


Now, as to your tank. 4 months is a bit young for SPS. You're also borderline on flow; I'd like to see something closer to 2000gph (50x for a 40gal). Lastly, phosphates at 0.25 are way too high for SPS. That'll kill most SPS by itself. You really want something like 0.00-0.03.

 

Thank you very much Evolved

i would put a panorama module or a par38. or there is this nice little dude that would light it great!
