EVO XII Unboxed
4 Stars
EVO XII Unboxed
This review is based on the consideration that I was not adding water for several days in any case but on a dry fit of equipment.This arrived a little over 24 hours ago and I will update as a resolution comes.Packaging was solid, the actual product is boxed in a printed cardboard box and well protected, this is further encased in another cardboard box that is slightly larger and offers protection to the printed container, mostly from errant box cutters. This second box is further packaged in another larger box with foam corner protection/suspension such that there are 'shock absorbers' on all 8 points of the inner container. All in all it is packaged very well.Unboxing the inner package, with the tank itself was not difficult. The innermost, printed box contains the tank and parts, again suspended on foam blocks with additional foam protection for the glass/fragile parts, and additionally the entire assembly was in a plastic bag.All pieces were accounted for.Upon closer inspection during a dry-fit of components it was found that the tube-bib leading from the return pump had been snapped off the threaded section (picture 1). This is a minor issue corrected immediately with superglue but indicative a shipping issue - the smaller diameter bib which is shipped loose (not screwed into the pump) arrived whole as expected.The most serious issue thus far is the light bar. It started to malfunction immediately upon being plugged in. No amount of attempting to activate the controlling button would change the mode of the light. Indeed the light did not illuminate at all but only flashed as seen in the video. Even upon unplug and restart it does not return to daylight setting but only this flashing.The tank itself is wonderful. I am especially fond of the raised base. The equipment bay is not large enough for an Aquatic Life 115 skimmer despite the claims on that product's reviews however it will only take a few minor modifications to make it work. It would be most appropriate to locate the skimmer in bay 2 and that requires further mods and usually the removal of the equipment bay lid. This should not be an issue even with jumpers but I cannot be sure unless I can get this setup working successfully.Bottom line is ~28 hours after receipt this is one star. I could not put water in it as shipped because the return pump was compromised. This means cycling the tank is cycling the tank is likewise compromised or at least seriously impeded. Most important though is the lighting issue. The benefit of an AIO is the convenience of not having to supply lighting as an external component.Thus far trying to get support has only led me a link directly to the supplier's website. I was not able to register my purchase for warranty at this website and my request for assistance there is pending. I was not at all impressed with their online market space or my ability to address this issue. My dissatisfaction is extended to Amazon as a whole as they are listed as the supplier (despite Hagen being the ultimate supplier).We will see what tomorrow brings.Update:I spoke to a gentleman in customer service named Julio this afternoon. It took less than 10 minutes to get a new light bar shipped out. The longest delay was my downloading invoice. Great customer service experience.

5.0 out of 5 stars Good starter and nano tank
Reviewed in the United States on March 22, 2022
Great setup for a beginner nano tank. Stock equipment can sustain live fish and soft corals.

Return pump could be a bit stronger but is sufficient.

I added a fluval nano light and removed the hood.

I also added a jebao SW-2 Nano power head, the fish live it, so do my softies.

If you can, plug the hole they left in the wall. The domino I had in the tank to start the nitrogen cycle get freaked out and swam into it, which damaged it and it died as a result.

They sell inserts to make it more like a sump but it’s not necessary.

I keep a 2-3 in sand bed. Arragonite sand and a caribsea live sand starter pack are what I used.

Get some live rock from an LFS and seed your tank with it.

Adding the protein skimmer isn’t required but it does pull out some of the organic material from the water column which has increased the clarity of water and stability of tank parameters.

I added small bioballs to the last chamber to increase biological filtration and that has worked very well.

You should also fit a second bag of ceramic along with the one provided so you can switch a new one in for an old one around 3-6 months

Make sure to push the middle chamber sponge pack so it’s submerged each time you clean it out (with water changes, in the waste salt water… not tap water)

Purchase a box or two of carbon filter bags and switch out monthly.

Return pump impeller and sponge can get gunked up so make sure to clean it regularly.

Don’t worry about sand/detritus on the bottom of the sump chambers, shake it up when you do monthly deep cleans.

Over all great tank for home or office. Could also serve as a great qt or sump if you upgraded to a larger tank.

Before getting into saltwater fish or reefing , do your homework.
Anybody claiming to have kept saltwater reef tanks successfully should instantly know this tanks flaws
Sponge is a nitrate trap ,didn’t use from start
Hood will cause tank to get to hot
reef lights that are good cost more than this whole tank
A small tank is less forgiving than a large tank when it comes to water parameters
Yet I still bought this product and happy with it, knowing what to expect
