Greetings All,

just wanted to share my piece of news - I am getting my second tank next week which will be 35G, I am buying it with all the staff included off a person whom I know and trust. It is a second-hand tank unfortunately but with some proper cleaning it will become a new home for my Kara and some other goldies who will appear later. On Monday I am going to bring it home and start setting it up.

More questions are on their way from my side as there will be some new types of equipment to be used and I am not sure if I am knowledgeable enough about it.

I hope you get it running quickly and smoothly oh and congratulations!

Eheim 2213 is a very good canister filter and is also one of the most quite out there when it is running. You can just use bio rings alone in there without carbon, which will allow it to house a lot of the nitrifying bacteria.

The tubings for the canister filter you can find at the Hardware store like Home Depot..etc.. You can replace the green Eheim tubings with the clear tubings at the HD store but make sure to get the tubings with the thick wall - not thin wall . The thick-walled tubing will allow it to handle the pressure from the intake side of the filter, which can collapse the tubing if it's too thin.

Other parts for the Eheim you can find on Ebay or online.

Congratz on the new tank!  Its going to look great! 

Well, in case someone is still interested in some more pics on my new tank being setup...

Today my wife and I painted the stand in black (it is rather old and worn) so it looks now fresher and nicer.
I tightened the screws and added 4 triangles at the corners of the stand at the back to reinforce a bit the stand just to give a bit of peace of mind for us to know the stand is up for the job again for another 150 kg.
We placed the new tank instead of our old 10G one.
Just added gravel (light brown coloured - looks similar to the one usually found in the rivers).
Added the water into the tank.

Filter is not connected yet though the parts I have ordered via ebay have already arrived. I will connect the filter tomorrow to the tank and will include a bit of media from the old tank - hopefully it will help with cycling.

Nice pictures. The stand is pretty, is it an aquarium stand?

The tank will cycle quickly if you're using things from an established tank. Mine was done under 10 days, I don't know exactly when because I wasn't testing the water in the beginning.

Why do you consider hard to keep it lean and nice? Is it because of algae covering it?

Yes it gets algae on the rocks super fast!  Like within a couple days of a gravel vac there is algae again and its not easy to keep the lighter colored ones clean or to get it off in the first place.  I was also finding a lot of gunk within the rocks when using the gravel vac and could not get it all out so I am taking some rocks out little by little and I want to just leave a very thin layer at the bottom in the end.   My tank is in the wall though so my situation is a bit harder to work with getting in the front corners and all.

Update:

Today I finally connected the filter to the tank and switched it on. Though I am a bit disappointed with its flow rate. I think this filter is rather weak for a 30G tank (which is not planted). I might consider buying another one to supplement this one. What would you recommend?

I have an Eheim 2217 in my 83 gallon, supported by a Fluval 4 canister filter on the inside I think the Fluval 4 on it's own would take good care of your tank though, so you may want a smaller size, like 3. That's what mom runs in her 20 gallon tank, so combining it with the external filter should be fine! I don't remember the exact flow rate of the 2213, but mine is filtering about 1500L/h.

In short, any internal canister filter would be fine, aim for one that is the appropriate size for the tank, it's always good with a small overkill when it comes to filtration for goldfish, especially since yours is a thinner-bodied type

Thank you for the recommendation. I will be looking into an internal filter to suppliment Eheim filter.

How lovely! That picture is so cute She looks so small and curious Can't wait to see the new fish there later!

Kara looks great, and I love shubunkins! Good luck with them

Today I have finally added a bubble wall powered by Tetra 40 air pump. I must say I really like it now - it's becoming beautiful and cozy for the fish. Because the pump is rather strong (up to 40G tanks) I plan to add anothe bubble wall.
In the video I show some driftwood - one piece is being aged atm. On the back wall there are first traces of algae. There are two bushes of anubias and they look really nice in the tank.

Max, Eheim Classics are some of the best filters ever made. Hands down. They are the oldest design on the market that is still in production for a reason... they work!

When set up properly it will be the only filter that you need. You should have the intake located in one corner in the lower half of the tank. The return should be located on the same end of the tank at the top and use a spray bar. The spray bar should be located right under the waters surface with a slight angle up on the jets. This will cause a ripple effect across the top of the tank. The water will travel to the other end, hit the wall and then be pushed back to the return along the bottom.
No air is needed. I have fought against that bit of misinformation for years in the hobby. The transfer of gas (oxygenation) occurs at the surface between the water and the air. Surface disturbance is what helps it along, not so much the bubbles, but the action of the bubble popping at the surface. When using a canister filter you get plenty of surface movement and therefore do not need an air pump. You can have one if you like, but you don't "need" it. I have run salt water tanks with bio loads that will look goldfish look like guppies and never once dropped an air stone in them. In fact, you don't want an air stone in a marine tank. It causes salt creep.

This isn't my tank, but as you can see, it ripples the surface very well.

If you would like I could show how to pack one properly. I had the 2217 for 15 years and tried many different set ups until I found what worked the best.
