What's new with Marisys 240 Pro Series 2?
Here at Aquarium Parts we've always been big fans of the Aqua One Marisys 240 and it seems we are not alone: the original Marisys 240 was an enormous sales success - thousands of units were sold in the UK alone and little wonder. For the first time marine keepers could have a fully integrated under tank 'sump' filtration system at reasonable cost and no need to DIY various elements - it worked straight out of the box
The Marisys 240 featured an excellent overflow box with peristaltic pump to prime it, a multi layer trickle filter, protein skimmer with air pump and high flow return pump.
The overflow box included a foam insert for safety and pre filtration, while the trickle filter included biomedia, a polymer wool fine filter pad, a carbon impregnated filter pad and a generous sachet of highly activated, phosphate free carbon chips. Naturally, all these filtration elements are available from stock at Aquarium Parts
The protein skimmer is air driven and can work very well if the collection cup is set to it's lowest level and the wooden air diffuser is exchanged every couple of months. Failure to do this leaves the skimmer struggling to produce sufficient foam and drastically lowers it's efficiency. Please note: few wooden diffusers are the right shape and size to fit the Marisys protein skimmer.
We have lost count of the amount of customers who have squeezed standard diffusers in only to find they couldn't get them out again in a few weeks….. Our advice? Stick to the original Aqua One Diffuser; they work well and wont make your life difficult down the line. We stock them in quantity so keep a spare or two around for a quick change over at clean out time
Marisys 240 Frequent Issues
Customers frequently contact us to say that their overflow box doesn't work as well as it did. In our experience this has two common causes - the first is that the hang on Perstaltic pump gets blocked up and deteriorates over time. Without good performance from the peristaltic pump the overflow box will trap air and slowly cease to function or not prime in the first place. The solution is simple: order a new peristaltic pump. We have the largest UK stock of these ready for immediate dispatch.
The second common overflow box issue is that the U shaped plastic section which carries water from the front of the overflow box to the rear (usually referred to as the bridge) gets very encrusted in reef set ups and will cease to function well - due it's shape it hard to clean. Sometimes a new one is the only option. These are available to special order: do call us if we can help
Return Pump Failure
The Marisys 240 return pump is a really tough, reliable item and with just a little TLC it will go on forever. But we do sell an awful lot of new ones to customers who have never cleaned theirs, never changed the impeller and never checked the return hose for blockages. Far better to remove and clean the return pump on a bi-monthly basis, change the impeller every year and the hoses every couple of years. A little bit of effort goes a long way with essential equipment.
Filter Media Renewal
Please, please change the marisys 240’s filter media on a regular basis – it will not work as designed if uncared for. Change the blue foam pad in the overflow box every few months to maintain flow rates. The white polymer pad in the top trickle filter tray is changed monthly, as are the carbon pad and the carbon sachet. Keep this up and your water will be crystal clear in the long term. Having clean filter media also helps to keep the skimmer and return pump clean and running well
Marisys 240 Pro Series 2
Never a company to stand still Aqua One constantly re engineer and improve their products. They looked long and hard at the Marisys and acknowledged that although it was good it could be made even better. A long development process has resulted in the Marisys 240 Pro Series 2. It’s fair to say that it improves on the original in every area. If you are looking for a complete marine filtration system we cannot recommend this latest version enough. We have detailed a few of the improvements below:
The Marisys 240 series two is now constructed from much darker tinted plastic. This prevents most types of algae from taking hold in any substantial way, the overflow box for example will no longer clog with coralline algae.
The latest overflow box is now self starting and does not require a peristaltic priming pump at all. There is now, quite literally, nothing to go wrong and the box starts time after time in a faultless manner. It’s very simple, very clever and it works superbly.
The Marisys 240 series 2 now features the latest needle wheel style pump protein skimmer which is really efficient and easy to get good results from. This is a huge performance upgrade and makes reef keeping so much easier.
To vastly reduce the amount of small bubbles which are returned to the aquarium the Marisys 240 Series 2 now features a special degassing chamber so the return water is as pure and clear as possible
What we think... Marisys 240 Pro series 2
The Aqua One Marisys Series 2 is now a really well developed filtration system that has no equal at anywhere near it’s price. A long warranty period is offered and, of course, Aquarium parts stock or can obtain every spare part, filter element and accessory available for this unit. No one knows more about Aqua one. Trust us to give you an unbeatable deal on the Marisys 240 Pro Series 2 and help make your set up a long term success.
