Oase biomaster 600 is this enough filtration?

[Magic8]

Probably within the next couple of months I’m going to be setting up a 75 gallon tank.

Will it be planted?

Yes not full blown aquascape but I will have plants

The type of fish?

I’m leaning towards an all barb tank but have not ruled out rainbows

My posts tend to become very long and let’s say others lose interest quickly so I’m going to make this short and to the point I will answer any questions and comments as they are asked

I have my reasons for loving the Oase biomaster

I cannot go with the 850 it’s too tall and will not fit in my stand

Will I be okay with putting a 600 on my tank with a couple of wave makers I know this filter is a bit underpowered but I think it has enough room in it for a good amount of media so I think I’ll be ok there (I know I need to half the # of 350gph being generous under optimal conditions let’s call it 225 gph max that only puts me at x3 turnover rate )

Its been suggested that I use x2 350’s that would be ideal but as you all know these filters are not cheap if I go this route I’m close to $700 before doing anything else!

I’ll leave it at this and wait to hear some opinions and any questions anyone has

Thank you

While 4 times per hour is generally the minimum recommended turnover, a planted tank would be around 6-10 times per hour to be able to cope with gazes exchange and provide a good delivery of nutrients to plants.

For a 75 Gallons, That would be around 300-375 GPH for a non planted tank, or 450-750 GPH for a planted tank.

If you get only one 250 or 350 and keep your 600 you will be close to 560 GPH - 620 GPH

I did not get anything yet!So you are suggesting going with x1 600 and x1 250 or 350

Esssentialy if I’m going to do that I’m probably better off going with x2 350’s

Like mentioned as far as water movement goes even if I went with only x1 filter (600) I will be adding a couple of wavemakers for water movement & circulation so flow is not going to be an issue it’s the turnover rate.

Will the 600 be big enough to handle the bio load,it’s pretty beefy and holds quite a bit of media if it was smaller and did not have that much room for media I would say no but it has quite a bit of room inside it so that’s why im kind of on the fence.

Two factors involved here

Lack of flow and circulation for gas exchange and such I can easily increase that in the tank itself with the wave makers

Turnover rate that’s fairly low with a tank this size but the filter is on the larger side and has room for a lot of media

It’s a tough call as these filters are not cheap.you get what you pay for I don’t think there are any other filters out there right now with the ease of maintenance that the Oase has the internal heater is not a deal breaker it’s kind of a bonus

I looked at the aquael ultra max 2000it has a similar prefilter almost double the gph but reviews are kind of a 50/50 mixed bag split on that and far less support in the U.S Oase from what I’ve read has top of the line support

Thank you

I have a Oase 600 Thermofilter on my heavily planted Aquael 240 litre tank. That's all. No wavemakers or additional filtration, or CO2 injection. It's heavily stocked with tetras and corydoras. [About 60 in all so far!]

I don't think you necessarily need more water volume turnover for the plants, unless you have CO2 injection. However, I do have to clean out my prefilter regularly each week, and I aim at 33% water changes each week. My Oase copes well from the biological filtration point of view, but its flow soon diminishes if I leave the prefilter alone for 10 days or more. Note that this is just my tank, however - others might have less fish and less feeding! I can cope with all this because I'm retired. If I had less time, I'd either reduce the number of fish, or add another similar canister filter.

Does this help? Tanks and stocking differ so much that you have to puzzle it through...
