Hi Niko,

Yes there is a bubble curtain right across the back. I put it there as a temporary measure as there is not much water movement until I put some power heads in late next week. The only movement right now is from the outlets of the two cannister filters.

Thanks for noticing and I'll take em out if you think it would be better.

Hope I can ask you guys another question.

I originally thought about putting a wavemaker in but I'm having second thoughts. I'm often away for days at a time and I want to have the whole tank on timers and keep it simple.

I'm now thinking of just plumbing in two seperate pumps each to an outlet on either end of the tank with a swivel outlet that moves. I don;t know much about what I would need. What would you suggest for a pump for either end?

One thing that needs to kept in mind here is the volume of water to get circulated..220 gal....

Personally, i would suggest something along the lines of 2 Seio M2600's..these offer about 2600 GPH water turn over...

The other alternative is the Koralia 4 powerheads ( 1200 gph ), but you would be needing 4 of these to give good water flow...

The above is based on having a water circulation of just over 20 times per hour.. ( 220 gal tank x 20 = 4400 GPH water turnover )...

If this is not going to be a reef, then you can effectivly half the above figures...

Niko, your an amazing help. Dunno what I'd do without you.
Those Koralia 4 powerheads look like just what i'm looking for and 4 would be fine.

I'm going to try to find some in Hong Kong on Friday.

If I can't find them can you suggest an on-line shop in the U.K because I need 230V and all the U.S stuff is 110V.

Also, I have heard that if a powerhead breaks it can leak oil into the water. Is this a concern?

If you ever plan a trip to China, let me know, love to be able to give some help back.

Thanks again for everything.

Hi Niko,
I shot of an email to the company in Italy that makes them and I think they'll have someone in H.K. I found other answers on this forum. Thanks again for pointing me in the right direction. Hopefully I'll have four in by the end of the week.

Yes, an oil lubricated powerhead will leak oil if broken... Rios are a brand that are oil lubricated and have a poor track record as far as reliability goes (from what I've read they almost certainly WILL break). Oil in your tank is a bad thing. The koralia's aren't oil lubricated, so with these it isn't a concern.

Thanks for your help dorkfish.

I'm hoping to pick up 4 koralia's this week and they certainly seem like my best option. Would they normally be placed one in each corner, or is it just trial and error?

 

[dingo_53]

Hate to be a pain.

My two remora pro skimmers just arrived.
I ordered them without pumps because I need 230V and they only offer 110V.

They suggest Rio 1400 or Mag Drive 3

I don't want to use a Rio pump because I'm worried about oil leakage.
I don't know about Mag Drive 3

Is there a pump I can use that won't have this problem?

 

[dingo_53]

Today I installed the 2 Remora Pro skimmers using Hydor L40 pumps running at the lowest seeing of 1400 lph. They are working well and seen like great skimmers.

I also added 3 Hydor Koralia 4's and 2 Koralia 3's for water circulation.

The tank is 220G with 230 kilos of live rock.

My question is that I also have 2 big cannisters filled with live rock. Do you think the above is enough filtration for a reef tank and that I can now remove the cannisters?
