OK after owning a week I thought I should warn you guys. Plugged in installed works very well adjustable flow through regulating the voltage on the controller. Although this is a good theory at heart its very inconsistent with the flow it puts out. Meaning the flow can be anywhere from 700 to 750 gph. The big downfall is after we lost power for 5 mins i noticed everything in my 100 gallon tank was on and running but something was off so I checked the pump and it had started to hum like it was struggling I lifted it out of the water and it started working again like it had to reprise itself. If your out all day and your pump stops working or on vacation this is a big no go for me. Ordering a different one now BEWARE...
I've wasted over $150 investing in both the 3000 & 4000, and neither one has the power to run a mere 4' tiered fountain as it should. Although perked with all kinds of unneeded 'bells and whistles' add-ons (see others' complaints on how 'well' THEY work!), both required additional parts (and know-how) from the local Ames Hardware to even function minimally. Live and learn …(!)
Update on the 4000: Will not run more than 5 minutes before it shuts itself off due to ‘error’. Moving on to another brand …
Further update: Seller offered to refund the cost of both models, … which I accepted. Thank you …!
Initial Purchase just quit after about a month. Replacement lasted about 9 moths give or take. 1st one just stopped working, 2d one won't draw water to operate fountain. They have a phone #....IN MAINLAND CHINA!!!!!!!!!! SENT E-MAILS TO 2 ADDRESSES, HAVE YET TO HEAR FROM ANYONE. ANY BETS THAT NOTHING GETS DONE!
Bought this pump for my reef tank, cycled my tank with the pump. Went to adjust the pump for higher flow since I only had it at 40%, the controller does not respond at all. Unplugged it to see it would reset, no luck. Paid for a 80 Watt Pump only getting 35 watts. Was please with it at first since it ran with no noise and no heat. But with it breaking after 2 months, I would not buy this pump
I really liked this pump but I can only give it one start because for close to $100 you would expect something to last for more than 7 months. This pump has been used submerged and has not moved since I got it it and has never run low on water. I also had it on the lowest power setting and it still failed me. I have several other pumps that have lasted me years so very disappointed with this hygger pump.
Terrible! I had one that lasted 5 YEARS There must me a NEW MANUFACTURER! The new one was used for 4! Months, stored over winter, would NOT work at all this SPRING! The Return is ONLY 1 MONTH! DO NOT BUY!!!@
Pump randomly stops working and show ER04 on the display. User manual says obstruction but it is installed in a empty chamber of the sump and there was nothing in there to begin with. I put in a few lines of codes in the APEX to restart it automatically every hour so it doesn't flood the skimmer but after a week I've decided that it is not worth it. I'll be looking buy other pumps.
This product stopped working five months after I installed it. I contacted the seller Petfocused who did work with me to find out what was wrong and when they determined it could not be fixed, sent me a new one. So I would rate Petfocused with five stars for customer service but the product as zero.
IF YOU VALUE YOUR HOME DO NOT USE THIS PUMP! This pump failed twice, causing floods in my home. The pump sucked water out of the DT to the sump causing flood. This happened one day out of warranty and Mago at Hygger refused to warranty this item. No concern or care for damage done to my home Hygger would not even return pump.
