Dr_Pepper Posted June 27, 2015 Share Posted June 27, 2015 Hey, I'm venturing into nano reefing after keeping freshwater for a long while. This reef will be built out of an older 10g tank I'm inheriting. It will live in my office so I'm trying to keep it as natural and quiet as possible. I picked up an orbit marine led light fixture. So I should have ample lighting. But the question is flow for corals. I have an eheim skim 350 surface skimmer that is listed as having a flow of up 350l which is a little over 90 gallons. I'm wondering with the relative shallowness of the tank - I know there is a crack in the very top of the glass so I won't be filling it 100% of the way to the brim anyways. The unit will extend just over 5" down and I'm so I'm left wondering if this will provide enough flow Also, with the goal of being as natural as possible, I plan on live sand and rock for bio filtering. I have an hob filter I got with my 55 gallon that I'm not using as I have a canister on it. I could turn it down and add it as well. It'd add some flow too, but is it necessary from a flow standpoint or filtration standpoint? Thanks! Link to comment
seabass Posted June 28, 2015 Share Posted June 28, 2015 Welcome to N-R.com. I see that the surface skimmer is rated for a tank up to 350L, but I don't see how much flow it actually produces. Depending on your livestock, you'll want between 25 to 50 times total turnover in your display tank (or 250 to 500gph for a ten gallon tank). If this is a standard 10 gallon tank, just buy a new one. A crack can easily spread when under pressure. A HOB filter can improve oxygenation, add flow, add a small amount of water volume, and provide room for chemical and mechanical filtration as needed. With live rock, additional biological filtration isn't usually required (or recommended). Link to comment
piano15 Posted June 28, 2015 Share Posted June 28, 2015 I second what seabass suggested. 10g tanks are pretty cheap, the pressure water will put on the crack could cost you a lot more than replacing the tank. An hob filter will add flow and a great place for mechanical filteration that and a powerhead should be good Link to comment
Dr_Pepper Posted July 16, 2015 Author Share Posted July 16, 2015 So just to wrap this up I suppose. I ended up attaching my HOB filter that is from my 55L kit, the Surface skimmer and a Koralia Nano 240 Seems to get lots of movement thus far. Link to comment
