Seaoura SR-703 is Total Garbage – Avoid at All Costs!
Rating: ⭐☆☆☆☆
I bought two Seaoura SR-703 filters, and they are easily the worst filters I have ever encountered in my life. If I could give them zero stars, I would.
Here is why you should never buy this model:
Pathetic Performance: On both units, the power dropped significantly after only two days. The flow becomes so weak that it loses all suction and fails to pull air through the venturi tube entirely.
Constant Clogging: This filter is a maintenance nightmare. I find myself having to open it up and clean it every 48 hours. Even after a "deep clean," it only runs at full strength for about half a day before the power cuts by more than 50% again.
Useless Design: A filter should be "set and forget" for at least a couple of weeks. The Seaoura SR-703 requires daily intervention just to keep the water moving. It’s a complete waste of time and money.
Bottom line: This product is poorly engineered and fails to perform its most basic function. Do not waste your money on Seaoura. Buy a reliable brand instead and save yourself the headache.
After two weeks there is no water flow at all. It just killed dozens of my shrimps and small fry.
Attempting to place another order for LED is constantly met with rejection and a refund after they tried to scam me and asked another $12 for the shipping after they clearly stated it is FREE.
This is an unreliable company, and I highly suggest you go with "WEEK AQUA" instead.
The build quality is terrible; there are visible gaps in the plastic joints of the LED SR 629 I bought.
On top of that, their filter design is completely flawed.
