My Fluval Roma 200

[paytertot]

I thought the fluval 206 was only rated for 40 gallons? That's what I have in my 55 gallon tank, along with an aquaclear 50

[jondamon]

It's rated for 45 US gallons or 200L.

Well so it says on the box anyway.

But I also don't plan on stocking heavily either.

Well 200 liters is more like 50 us gallons and fluvals are known for having slightly lower flow than they say. I would stick an aquaclear on there too

[jondamon]

I've got a fluval U2 internal filter which will probably go across from the 35litre but as long as all my water tests are stable and fish seem happy once established then I'll be happy.

Update on testing

So as you can see, yesterday I had 4 ppm of ammonia lots of nitrites and a little nitrates

Today I have 1 ppm of ammonia more nitrites and slightly more nitrates.


Thanks for stopping by.

So here are today's test results.

I added ammonia yesterday up to 4ppm and today the ammo is right down with high nitrites and still no real change in nitrates.

Hey everyone.

I am currently having to add ammonia into my tank twice within 24hours.

It is taking a lot less time now to convert Ammonia into Nitrites.

But I'm not really getting a Nitrite - Nitrate conversion happening yet.

I'm leaving my tank as it is until Saturday and if I have no change in Nitrate levels I will perform a 50% PWC to lower Nitrites and re-buffer the water.


Any advice from those who have completed a fishless cycle?

Do you think this is the right plan of action? I will have waited a week for the nitrite - nitrate conversion to start but am concerned at my excessively high Nitrites might stall my cycle.


What do you think?

What are your nitrite levels? If they are off the scale, you should do a water change to bring them back to a readable level. If this is happening, it could be stalling the cycle

Levels are off the scale and have been for several days.

50% PWC on the cards for me in a few hours.

Thanks for the help.

Have performed a 50% PWC levels are still 5ppm nitrite.

I will perform a second 50% PWC tomorrow.

If levels are still at 5ppm I will perform a consecutive 50% PWC straight after the first one tomorrow.

Thanks again.
