Hi, I’ve just bought my own display tank as I fancied doing my own setup, stand, sump and plumbing etc myself. Im stuck between which overflow to buy between the 2 types attached. The shorter box would be good because it takes less space, however it means the plumbing is at the back of the...

Fiji Cube just confirmed to me that when you purchase a stand-alone Fiji overflow box (1600, 2000 or 2400 model) they DO NOT work out of the box for Fiji 3/4" glass tanks (including the Fiji 171gal) - despite the compatibility matrix published on their website that says the box works with...

Hello everyone, I need a little help with this issue I’m having. Hey everyone quick question. This isn’t my first tank, but it is my first tank with a sump. I’ve got the gate valve pretty dialed in, just need a little adjustment, but the overflow is so freaking loud. Any advice how to silence...

Hello everyone, after several freshwater tanks and months of saving up and research I’m finally looking to start my first saltwater tank. I am planning on diving head-first and doing a 96x30x30 acrylic mixed reef tank for my home office. The first area I’m having difficulty finding in my...

Hi all! For a little background, my boyfriend has been planning his reef tank for about eight years (he even chose his apartment in the city he lived in before we met so it could sustain a 400 gallon reef tank). After a 29 gallon gift, 100 gallon tank COVID project, we now have a 100gal tank...

I've read as many posts as I can find (including Bean's original thread) but I can't seem to get some of the subtleties. I've implemented it pretty much as Bean did in his original thread and I've got it tuned and it seems to be stable. It's on a 90 gallon display tank that's two feet by two...

So, I've seen this style of low profile overflow that is a lot cheaper than the type that has a whole box attached to the back of the tank. The problem Is, I'm not finding a whole lot on how to plumb this type of overflow. Just seems like if I just drill a hole, attach a bulkhead and silicone...
