Catastrophic product...inacurate compare to two or three other salanity checker...as neptune, milwaukkee and on and on

Offset by 2 ppt....
Ot seems that hanna is using another calibration solution......

If you calibrate it with neptune solution...it will resd as neptune is....

If you calibrate it with accurasea it will read as othernthat have been calibrated with it...

But when calibrated with hanna liquids......
Ot will then be offset......
Hanna keep saying that their products is THE one that must be followed....
Your choice to decide.....

@ Hugo we appreciate your review, we helped you last month and determined the unit was defective and also agreed to send you a new one once we got the bad one back. Im not sure why you would rather review a defective unit rather than getting it replaced under warranty. Your choice to decide I guess

Advantages: Temp compensation

Disadvantages: Offset by two ppt compare to other calibration solution

Can only use it outside the tank! You can't even glue a frag plug to rock inside the tank as it hardens within seconds!

@ Albert, Reef Welder will harden as it cools. It will harden within seconds once it enter the water.

In short; I’m pretty disappointed in the construction of the visors however they do their job quite well. The reason I’m giving a low star rating is because the cost should definitely be lower, they feel unfinished with rough edges (not that big of an issue), but mainly the hinge part is what bothers me most. What I would say could of been made better is having an optional screw part that allows you to physically screw then in rather than pushing them in. Secondly, having the hinge be a bit bigger for durability and perhaps smoothing it out so it isn’t so rough allowing for better control and looks.

The only other thing I would suggest is having colour options like white for the white primes. The size is decent, perhaps try out making the visors have a curve in them to make them more modern and fitting with the lights.

Otherwise it does do its job like I mentioned. Just could be some improvements. I am still thankful for these.

Advantages: - They work well!
- Good size

Disadvantages: - Not the best of finishes
- Hinge could be better
- Perhaps white for a colour/tone

This customer purchased the item at our site.
I used these fittings to replace my Red Sea nano stock sump with an Eshopps nano refugium dual channel (patent pending) sump, which fits perfectly in the cabinet, but allows for use of a refugium and a protein skimmer simultaneously and maximizes the use of the space available.

If you plan on customizing your plumbing you will need these fittings.

Advantages: Hard plumbing/custom plumbing for your specific needs/ sump upgrade.

Disadvantages: Metric threads I think. So male thread PVC fittings are hard to find that fit into the female threads of these fittings. With a bit of ingenuity you can transfer to National Pipe Thread (NPT) and then you’re all set.

This customer purchased the item at our site.
This is an amazing system. Well designed and thought out plumbing arrangement. Once the overflow is dialled in it is truly silent. I am very picky with noise, and this meets my expectations. There is obvious attention to detail with the silicone seams, they are straight, solid, and true. The entire system is a bit pricey compared to other lower cost options, however you do get what you pay for. One thing I did do was paint the outside of the sump white, and I installed an under cabinet light in the stand. It makes maintenance a lot easier. Be careful when you install the tank on the stand, it is supposed to hang over the front a bit and line up with the doors when they are closed. I positioned mine too far back and had to adjust the tank when I started to attach the plumbing. The shipping box was a bit dented and wrinkled when I received it, however there is lots of room and styrofoam to absorb the dents.

This customer purchased the item at our site.
What can I say, it is an adapter. It fits as expected, I was originally unsure if the slip side would be a solid fit, however it fit nice and snug. It is a bit rough as it is a 3D printed part.

Advantages: Allows you to adapt a loc-line fitting to your reefer system.

The product was dry..I had just finished using another brand and when I broke it I got zero crumbs..this one when you break it crumbs everywhere because its dried out....not great. The fish seemed to like the other product better also...

Advantages: zip lock is convienient for trying to keep it fresh...

Disadvantages: product seemed old and dried out too much...did not seem fresh..makes me think it is old inventory...I could be wrong...but thats how I feel...

Kevin Maguire about  Collapsible Fish Trap - Medium:
Sep 23, 2019
Excellent trap. Caught a yellow peel dwarf angel within an hour...kinda thought it would be a couple of days. The advise I received was only feed the tank by using the cylinder in the trap to get the fish used to entering it...

This little thing is amazing!
Unboxed it about an hour ago, put it all together and put it in my sump. Believe this or not there is skimate churning as we speak!! This is a big deal for me because for 2 years i have run a Deltec MC500 and have NEVER managed to get it to tune right. This little baby tuned right up and we are off to the races. I am sure as it breaks in i will have to fiddle with it some more but for the here and now i am thoroughly impressed

Advantages: -Excellent Build Quality
-P R I C E
-Over flow Pump shut off
-Easily Tune-able
-Compact Size
-DC Pump running at 10W

Disadvantages: Uh.... i didn't own it 2 years ago??
Ill update if/when i find any

Purchased this less than a year ago and have always kept up with cleaning but the motor no longer spins the cages correctly. It simply twitches. Replaced all the bushing as well with no success. Worst pump I've ever owned...

This customer purchased the item at our site.
I received advise that this would be a good ATO to use with my 14 Gallon IM NUVO AIO peninsula tank. The prior ATO I had been using wasn't able to detect the water level and would constantly overfill. This has been installed for a few weeks now and works like a charm. I tested it by purposefully overfilling the tank and it set off the alarm. Its not deafeningly loud, but its enough to get your attention.

Advantages: Incredibly small, really easy to set up and install.

Disadvantages: No mechanical backup or secondary float backup, both sensors are enclosed in the same module. This is why it is so small, but may not provide peace of mind some people want.

Andy Boldt about  Fauna Marin Bacto Reef Balls 250ml:
Sep 11, 2019
This customer purchased the item at our site.
I operate a 75 gallon marine aquarium with a 45 gallon sump. My tanks were in good condition with good water quality and minimal algae growth. This product was of interest as an enhancement to my routine maintenance program. I have only used this product for about a month and have definitely noticed improved water clarity and a positive impact on algae control. No apparent detrimental effects to coral or fish. Internal glass surfaces remain cleaner longer.

Advantages: Improved water quality and deterrent to algae growth. Extremely easy to use and long lasting.

Disadvantages: None.

does the trick to supplement 2 XR30 Pro Radion LED. Full coverage now without shadowing. Coral are liking the extra light.

Advantages: easy assembly, fits over a 120G perfectly, Radions fit nicely, hanging kit included, not $1000's of dollars like other programmable fixtures

Disadvantages: no on/off switch, power is at opposite ends of the fixture so both ballast will not reach my controller, not dimmable but I knew that before I purchased
