Right, its been a while since you explained lighting, but can just say that overall, Halides are cheaper than T5s. Halide units may be more expensive, but the bulbs only need changing every 3 years or so, while T5s need replacing once a year.

Depends which Halide Bulbs you go for, some can be about ?10-20, but the Pendants are the expensive part :angry:

Pendants are expensive with T5s aswell. Well, if you go for pendants, you don't really have a choice with halides.

Sorry - what's a pendant? (Never gone for Halides yet - I have a white phos U tube..)

Rather than lights that attach to the hood, they hang down like a pendant from the cieling etc.

Ahhhh. I see. I would of thought a hood one is more practical - or one on those custom stands you can get.

Those custom stands are a different type of "hosting" lighting called overtank luminare. With T8s and T5s hood usually are more practical, but as Halides get so hot (for tank lighting) the tank must have an open top too compensate for the heat.

T5/T8 and Halide Pendants/Luminaires are all in the same sort of design. They are supported over the tank by either legs that attach to the tank or cables which suspend it over the tank.

With the smaller T5s you can put them in a closed hood (I have mine in a closed hood on my Nano) but with higher powered ones it would be better as open top (which is what I am doing with my Pico, 36w over 2.5g :P )

If I get T5s I will use a hood. Making my own will be cheaper than buying a luminare unit. If its halides, it'll be a pendant.

I seem to be misplacing threads, I am sure I couldnt find this one the other day, but yeah.... I was realy busy with college and work before christmas so I didn't really have much time. I am, however, off work for a few days now so I will get to work on part 3 ^_^

Part 3: Maintenance and Stocking is coming right up

<span style='font-size:14pt;line-height:100%'>Part 3: Maintenance and Stocking</span>

First off, just a little introduction to possibly one of the most important issues in Nano-reef keeping. The reason these little systems are possible is actually the keeper, regular maintenance and sensible stocking levels are what makes these little systems work like they do.

Maintenance:
As explained above, this a very important part Nano-reef keeping. Not only does it remove waste from the tank but it also replenishes the trace elements that have been used up by the tank inhabitants. The main part of maintenance is of course the water changes, these can be done weekly or bi-weekly depending on the stocking levels in your tank. Water changes are quick and easy to do, to make it even quicker you could have the saltwater already mixed in a suitable container so then you can just use it when it is time for a water change. The saltwater for water changes should be mixed at least 24 hours before the water change is due; this is basically due to pH doing a lot of fluctuating.

Please note that while doing water changes, try not to get any saltwater in your mouth while starting the siphon?. It tastes incredibly bad

Whilst performing the water change you will probably want to remove any detritus from the gravel as well as clean the front and side panels of the aquarium. Algae does seem to grow extremely fast in an unbalanced aquarium so this is why stocking levels need to be thought about very carefully.

Next to water changes is evaporation top-off. This is also a very important part of the maintenance because not only does it keep the water level the same but more importantly it keeps the specific gravity at the same level. There is nothing worse than a fluctuating specific gravity because it can cause extreme damage to your reef. Top-offs should be done with freshwater as you are just replacing the H<sub>2</sub>O that has evaporated and not the actual salt from the water.

To clean off any salt residue DO NOT use any chemical cleaners, only use freshwater to get rid of it.

Stocking
OK, so this is the part that can cause some extremely sore heads. Stocking can either be a fun part of setting up or a complete nightmare for someone who has not done his or her research.

Realistically, Nano-reefs are set up to be invertebrate only systems, which is all good for those of us who set out to do that, but what about those of us who want fish? Well, this is the hard choice that we have to make; hopefully this part of the article will help you make up your mind.

Firstly, the size of your tank plays a big part in what you can keep. I would suggest that a tank no smaller than 7g is to have any fish in. Fish have been put into smaller systems but these systems do require a lot more maintenance. The fish selections are up to you as the keeper, there is lots of sites out there that give information on specific fish so if you are in doubt, refer to them.

Any tank right from the smallest Pico-Reefs right up to the largest Reefs can have corals in, but even these need to be chosen carefully due to aggression levels. The corals that mainly cause problems are Large Polyp Stonies, aka LPS and Small Polyp Stonies, aka SPS. LPS tend to do damage with sweeper tentacles so they shouldn?t really be placed close to each other, whereas the SPS corals concentrate more on chemical warfare, this being the reason SPS corals are not really seen in Nano systems.







Again, any questions or anything else I should add just let me know ^_^
