Thread: Oase auto top up

Anyone using the Oase auto top up gadget? it seems a bit pricey compared to the Proline one. I guess they both work but is one better?

I owned the proline one for 10 years and didn't fit it. Finally got around to fitting it 3 weeks ago just before the cold spell and it looked like it was going to the do the job. Cold spell finished and I thought I'd double check everything and low and behold it'd stopped working. I opened it up and much to my horror there's around £9 of components inside - its terrible. No PCB, just components soldered to each other. I couldn't be bothered to fault find it so I bought the Oase one which arrived yesterday and I fitted it tonight. Seems to just work as described. The solenoid is heavy duty where as the proline one was feeble. I got mine from Lincs aquatics for £339 which was the cheapest I could find.

Hmm thanks, guess you get what you pay for

Could just have a trickle in with an overflow

Unless you're on a water meter and then it can work out expensive.

Yup watermeter

Not really if you set the flow to a rate that completes your weekly water changes for you.

Your are already £500 down and that’s a lot of water

Trickle in and over flow out has worked for me around 30 years ok koi keeping. I’m building a new pond starting in a week or so.
I’m fitting a new cattle trough rise and fall ball valve £13.00 eBay, a tough ball valve.
Fitting them both in my skimmer. Cheep low tech & very effective. Obviously after a de Lori story! My’n is a big blue.

Yes i agree a float valve would work but I did not think of it when I did the pond and to fit one now will be a bit of a problem.

I just have the standard pool skimmer and I dont think it will fit inside.

£30 on a flow meter and some maths

The one thing I have against a trickle is when I clean filters my water level drops and it would take hours to get back to level.

Spot on Ukzero this is the right way to do it. But you Do need a big blue really as a small dechlorinator can’t handle a large flow. I’ve bought a big blue for exactly this reason my standard 3 stage pre filter didn’t have the umf to cut the mustered on more larger flow rates.
