Need some help with bulkheads and other stuff (1 Viewer)

[Aggie05]

So I am thinking about jumping on the SPS bandwagon and have some questions. First, this will be on a 10 gallon with a 70 watt MH and 32 PC actinic lighing. I plan on running a overflow to a sump with a mag 3 for return through a SCWD. My questions are, what size bulkheads should I use? Also, will the mag 3 provided enough flow for SPS? And lastly, this isn't really a DIY question, but the current resident in the 10 are two firefish, will they be ok with heavier flow?

Edit: I also forgot to ask if using an overflow like a pet store uses would be ok. I don't want to have a standpipe so I was thinking of having an overflow near the top of the tank with a pvc elbow for it to overflow into. Is this noisy, because it will be in my room.

WOW, this is an old unanswered post....

You COULD probably use 3/4" bulkheads, but you really only need ONE outflow bulkhead. You can drill it high on the back of the tank, then enclose it in a acrylic box and run it down to the sump. I personally woudl SCWD two "hang-on" type returns that clamp to the lip of the tank. The lets you move them easily/ change their size without any glass work....

This type of system is actually very quiet (I have one running on my 20g upstairs)

The firefish will be fine. Mine seem to enjoy the gauntlet of currents as they swim from one side of the tank to the other

Isn't it kind of risky to drill a 10G? I thought that you run a good chance of cracking the glass because it's so thin.

Yeah, but if you crack it, you go plop down $10 on another one.
