Problems with new Nero 5 pumps

[Aneasytarget]

They should be giving us the new magnets but they won’t. Sc__wed indeed.

Well I'll be! Just went to AI site to look up Nero 5 and NOW thickness of glass is 0.63" (16mm)!
Looks like they upgraded the magnets because the ones I bought last year where rated for glass thickness of 12mm which is just under 1/2" ( 0.47"). Looks like they told no one. My box was rectangle now they're more square like. Great for new purchasers but what about me & others that have the old weaker magnets? Are we going to be able to get stronger magnets or just get sc__wed.

Nope, you're not the only one. Lost him a couple days later.
Removed the Nero5. Using in the sump now.

Ugh.... I emailed them to make a shield .

I saw them on Ebay.

Nero 5 Snail Guard | Melev's Reef

This is a 3d printed cage that fits around the back end of the Nero 5 pump. Keep your livestock safely away from the back of the pump. This would include fish, snails and anemones.

The bottom line is that the rear of the Nero 5 is poorly designed and by now they know it. They refuse to address this issue properly and I seriously doubt I would ever purchase from Ai again. :mad:

I agree , I got my shields off of Melev’s reef

Marc @ Melevsreef has been an amazing partner for me. That guy is a huge boon to the community.

I agree, when I ordered my guard he shipped it immediately.

I was wondering if you are still having any concerns or issues after installing the guard? I am considering buying two of these but this problem has to be addressed (even by 3rd party if it must be) before I will buy

 

[TheKingInYellow]

I know one guy still lost a small fish with the guard, but that's about it.

Melevsreef and Reefsupplies.ca have sold probably close to six or seven hundred now, plus all those that printed their own, and that's the only negative feedback I've received.

Well then, I think I will be buying a couple and some guards from Melevsreef! Hey, thanks for building these things. What is amazing about this hobby is how people like you take your personal time to help us out! I truly hope you were able to pull some kind of profit off of these even though some low life stole your design!

 

[TheKingInYellow]

Well I originally designed and released it for free, and the design is still free for personal use if you have a printer.

I do make a few bucks on each that are sold at retail which I started doing when other people starred selling my design. I just used that money to buy Corals and more printers lol.

I just read through this entire thread and I saw where you have the design available for anyone. I do have access to a printer at work but.......for me to use it would be like trying to speak German......it just isn't going to happen. I will spend $40 and be done with it and support people like you doing this for us. It isn't much but maybe you could buy 1/5th a coral with my purchase.....hope she is beauty :)

Even with the extra $20 for the guards, these are fantastic wavemakers for the price. I have one of the Melev Reefs guards on mine and the holes are small enough to keep even my neon goby out.

That is great to hear. They do seem like really amazing pumps and now that they are on sale for $200 on BRS, they are hard to pass up. It does appear that the magnet problems have been solved (be it at the expense to those of who that acted, unknowingly, as the beta testers....not good AI) and if 3rd party 3D printed guards are available....they are significantly cheaper than Mp40s and have flow characteristics for a nano with room to install on a larger tank. People either love them or hate them; but they do offer pretty unique flexibility and design.

The opening for the power cable is a little too large and small snails can enter. I stuffed the opening with a little bit of filter floss to plug it.

I also increased the flow to compensate for the guard and always make sure to keep the guard firmly pressed against the glass.

 

[TheKingInYellow]

Yeah that was a design decision to prevent damage to the cable. Also fileting the inner edge of the gap to prevent sharp edges from touching the cable, it's really thin.

Thanks guys. I made the purchase of the neros and the guards! I really think they are going to help me. I do have some snails breeding the tank and lots of little buggers all over, so thanks for the tip on the cord opening! You guys have been great. Thanks again! I will post back to this post about the box shape (since that seems to be a factor considering a possible change by AI to the magnet strength) and I will give my honest opinion about whether the magnet stays in place.

Received response from AI asking for video of weak magnet side holding pump. (*I have 2 of these pumps with same problem). 1st vid shows by just touching or trying to adjust angle pumps easily falls off. 2nd vid is pump on pulse mode - 35% - each time it revs up it moves a little back & forth. Remember AI says Nero's are good for up to 1/2" ( 12.7mm). My glass is 12mm - 0.47" so technically I shouldn't be having any problems. *No algae on glass, I clean every other day.

Did they fix the Magnets?

I heard the new ones are shipping with fish guards.
