Frag/Invert QT Setup

kswan · Sep 29, 2018

After introducing velvet into my system through some frags traded locally I have decided to set up a frag/invert QT system that will be separate from my display.

My display is a Reefer XL 425 (90 gallon). I have a 40 breeder that is my current fish QT and a 20 long that was my previous fish QT. My thought is to use the 20 as a frag/invert QT but I’m not sure the best way to set it up. I have a Hydra 26 for a light which is the same as my display.

Is the 20 long a good idea? Should I drill and add a sump or setup as an AIO? Would a different tank be better? I’m just looking for some feedback and advice before jumping into this.

20 gallon is ideal for frag and invert QT. I use a Aquaclear 50 HOB, small Hydor 240 powerhead to keep things moving and clean.

I think the 20 long would be fine. With the very low bioload I think you could run it with a HOB filter with media/live rock rubble. If you feel adventurous you could drill it and run a sump.

Ok. So it sounds like I’m on the right track. Any thoughts on HOB vs sump?

For a QT, IMO HOB is more than enough. Most coral I have QTd was done in Rubbermaid bins with no filtration (just a heater and powerhead) and it worked fine.

That light will need to be well above the tank and ran fairly low IMO as well.

I do use a RSR nano now as invert and coral QT with a prime HD over it. No filtration in the sump. Just houses ATO and a heater.

a hang on back is almost overkill unless you have one laying around.

I mean, it's not like corals make a mess. I have a sponge filter in my coral QT.

once a week I take 5 gallons from my DT and use it to do a waterchange on the coral QT.
