DIY light fixtures and filters and splashing

I was considering a diy light fixture like the one listed at AH supply (I would also do the custom wooden hood they show) but it occurs to me that maybe it won't work with my filter. I have a bio-wheel powered filter that hangs on the back of my tank. It really doesn't have a flow control on it so water spits out at a good rate. To keep the sound down I have to keep the water level up high. This causes a good deal of agitation at the surface around the middle of the tank (29g).

With my current 29g kit this isn't too bad since the platic hood blocks the splashing and my 20w light sits on top of the plastic. Looking forward I saw the potential for a big problem if I switched to the diy hood. I assume you're supposed to have some plexy or glass sitting on the tank and the light is on the plexy/glass. But even then it seems like the splash will get the wooden light fixture, or at least it could.

Am I correct in assuming that most people who have diy lights also use a cannister filter to avoid splash? Is it almost required?

from what I understand the canister is more for co2 addition and reducing out gassing. It seems to me that you could just add a splash guard. I also rember reading somewhere that putting a sponge in the outflow will reduce your splashing.

I hadn't thought of co2 being the reason for canister. You're probably right. Then people don't have to concern themselves with splash because of that previous decision to go canister. I may be one of the few with this type of setup.

I haven't seen any mentions of splash guards in my research. Seems like most don't need it or it's just a given somehow. I also don't see any mention to cutting glass for the light or the top of the tank - again sort of like it's a given. I'm afraid I'm missing something basic at this point. It may occur to me after I had the light fixture done but I'd hate to complete the project to find a problem at the end.

The sponge is an interesting idea. I'll have to look for something at the LFS next time I'm out. As long as it didn't stop the flow of water it should help.
