i narrow it down to two MH

not the 250 but making a 150 watt for 299 including shiping
and
http://oceanencounter.com/Merchant2/...egory_Code=AMO
for 252 including shiping
this is for a 20 gallon tall and to support clams
so what would your recommand?

[Reefer769]

i would say go with the first one, marine depot is selling that fixture for 299$ and it comes with everything you need, and you would be able to hold more corals/clams under that lighting.


that is the exact light im looking to get, but right now i dont have enough money for it MAYBE next year!

at oceanencouter it is 299 including shipping compare to 313 at marine depotive.

[Reefer769]

alright well i guess go with the better deal, my fault.

To be completely honest, the Aquamedic fixture would be a great addition to your 20gal tank. However the 250w does provide more useful light and would be a better choice especially if you plan to upgrade in the future.

some reefer say 250 is over kill for a 20 gallon and create heat issue. but if you recommand 250 i will consider it. who else agre with reefland.

[Reefland]

Sure, heat can be an issue with any MH. If you experience heat issues, you will need to make sure your canopy is well ventilated and if needed, add a fan or 2.

As far as a 250w light being an overkill; you can never add too much light to a tank.

that what i heard too so should i go for the Aquamedic 250watt? do you think this is agood deal? i will build a hood with two fan one input and one output. but i like poeple input on items im goin to buy.

[Reefland]

Yeah that's a pretty good deal, I am pretty sure you'll be pleased with it as well.

Do you plan to use anything for actinics or just running the MH? If you are just going to run the MH and like a lot of blue, go for the 20k bulb otherwise go for the 10k.

[Rp Marine]

i do like alot of blue. so i think i'm goin to get the 20k. i also have 4x13watt kit do u think i need to use it?

[Reefland]

No I don't think you will need to incorporate the 4x13 watt if your going with a 20k. It;s a personal preference though; I run my 10ks alone, no actinic supplementation.

[Rp Marine]

with the 250 watt how much space should between the water and MH? and can i use pexie glass ans a shiled between the water and the MH ?

[Reefland]

I wouldn't bother with any type of covering over the tank.

Optimum height would be between 7" and 11".

[Rp Marine]

is it ok to do a covering because i think i will put mh about 6 inch from the water do you think this be ok?

[Reefland]

No I would not do a covering. It can reduce the amount of light that penetrates through the water column and can cause an additional heat problem; more so that a MH being 6" from the surface.

[Rp Marine]

how would i create air flow with out letting the air blow at the water?
