Review: Effortless filtration and crystal clear water - This is the greatest aquarium filter ever! I’ve tried other styles and brands. I now own (3) of these. 1) the integrated heater is great and eliminates having it the tank 2) the pre-filter makes routine maintenance a dream to complete 3) the flow rate is fantastic 4) the ability to customize the media trays is a huge plus I run heavy planted and stocked tanks. The OASE filter exceeds my expectations!
Review: Nice filter but expensive - i have a 350 thermal on our 36 gallon and a 600 thermal on our 75 gallon. The prefilter feature is great and i love the heater in the filter. Both filters are with sponges in bottom tray and biohome in the rest of the trays. The flow on the 36 gallon with 350 thermal is excellent the 75 gallon with biomaster thermal 600 i wish had a little more flow. Both filters are going through a uv sterilizer on the out line. Heater seems to work perfectly on both units. i had an issue getting the rubber feet to stay on the 600 but other than that and wishing for more flow on the 75 gallon. i am happy with both units. Tip if your impeller is rattling you most likely have water in the head take some water out of the canister and restart it. Both units are very, almost dead quiet make the units perfect for a bedroom. I recommend replacing the 60ppi pre filter sponges with the 40ppi replacements seems to help a little with flow. Over all the biomasters are good filters.

## Features

- THE MOST CONVENIENT CANISTER FILTER ON THE MARKET – The BioMaster's EasyClean Pre-filter module can be removed separately from the rest of the filter. This makes maintenance fast and simple. It also increases filter efficiency and extends the life of main filter foams.

- BUILT-IN SAFETY FEATURES - Designed with safety locks on the handle, pre-filter, and aquastop to avoid spills during maintenance. The aquastop is detachable for easy movement of the filter without affecting the tubing setup.
- QUALITY DESIGN – Made in Italy, with German engineering from OASE and backed by a 4-year warranty (3 + 1 year with online registration).

### ⭐⭐⭐⭐⭐ Saltwater Ready
*by J***R on October 8, 2024*

Using the 600 on a 40G breeder tank for over a year. Basically, I have this canister feed a 25 watt UV & a MacroAlgae reactor that has Cheato algae in it. I use the pre filter sponges & the 1st thin brown sponge. The rest of the trays have 5lbs of biohome branded biomedia. That leaves a tray for any other media of your choosing. I clean the easy accessible pre filter every couple weeks. After a year, I replaced the brown sponge & rinse the biomedia with tank water, that's it. I have never had a nitrate issue. You can't hear it running, the flow rate is around 300gph, perfect for the UV & Algae Reactor, & maintenance is easy. If you let the prefilter go too long without rinsing, the flow is diminished. Stay on top of rinsing the prefilter. The prefilter is simple to clean, unplug the filter, unlock the plumbing lines, the unlock the prefilter tube and remove. You don't even have to take the top off the top of the canister to service.
