The start of my new 65 gallon.

This is what i have so far.

• 65 gallon acrylic with a DIY stand(built in about 2 hours, it was the easiest thing I have ever built with a lot of help from a friend )
• 2x MJ1200 with Sureflow mods 4200 GPH!!!(wired into a dual dimmer switch to control the speed of each independently)
• 1x 48" 260w PC
• 1x Cascade 300 filter
• 50lbs of live sand
• Undecided on live rock(maybe base rock and seed)

• Fish(all in my 10 gallon QT from my 20 gallon crash)​
• 2x Blue/Green chromis​
• 1x Ocellaris​
• 1x Coral Banded Shrimp​
• 2x snails​

The Stand and Tank​

​

The powerhead control(mounted behind door...yes i know its for a light and fan, but idc )
​

 

Very nice! What are the dimensions? Also, Im not an experienced electrician at all, but I thought that you couldn't wire pumps to dimmer switches.....something to do with going from AC to DC I think? I could be way off, but you might want to look into that.......

 

the dimensions are 48x18x17, i though about that to with the electricity...i figured if you can to it to a light and a fan, why not a powerhead(underwater fan). They work fine although I havent ran them very long because they were out of the water....hope to be filling the tank up within the next hour and will let you know how they do....NEED TO GET THIS TANK CYCLING

 

lookin good bt. if you have concerns, i know reefsparky is an electrician , he could tell you yea or nay.

 

Nice looking tank bt, im jealous im just getting my 65 up and running but I wish mine was longer like that cept mines tall stupid tangs gotta have large swimming room grrrrrr. Have fun and keep us updated.

 

I to would be cautious about a dimmer switch.

My question for you is WHY mod it if you are just going to dial it down with a dimmer switch isnt that counter productive?

 

well i modded them for higher flow but i also wanted to be able to turn them down but not completely off, such as when im feeding them or doing water changes. im currently running them full speed at the moment, which is where i will keep them 99% of the time.

tank is filled and the cycle has begun

 

The dimmer switches will work to an extent. It's in essence, restricting power to the powerhead. As you twist the switch i believe it creates more resistance, which lowers the powerhead speed. A controller actually controls the Alternating Current (AC) as it flows through the Direct Current (DC) powerhead (which is why only certain powerheads can be used on a controller). If your powerhead is AC then you cannot use them on a controller.

EDIT: Or is this the wavemaker explanation??? I think it's the wave-maker one. Yeah, if you dim it too far the magnet drive wont turn fast enough to run the prop.

 

yeah, if i turn it down to low the prop begins to vibrate

 

Lol bt I wanna see pics of the tank filled!
