Setting up the Orca TL-450
Published by StoneCold on 15/2/2007 (60252 reads)
Like a lot of other people on here, I purchased the Orca TL-450 13gl Nano Marine tank and like everybody else seems to have, I too found it very difficult to begin with. This was due,in large, to the general 'lack' of detail and information that comes with this tank.
Since originally setting up my tank I have gained a fair amount of knowledge about this tank and its faults and features. Having answered a fair few queries about this tank and, with the fact that its seems to be a very popular and common choice amongst new keepers to the world of marine, I thought I would share some of the knowledge I have gained and jot down this information, in the hope that others would find it both informative and helpful?
I will start with the tanks features and set-up.
The Orca is a 'plug and play' tank, this simply means that it contains all you need in its set up to get started straight away.
Starting from the back of the tank and reading L to R there are 4 chambers.
1st left is the return chamber, this is were the water is eventually returned to the tank after being pumped through the tanks filter system. This chamber also contains ceramic noodles, which are part of the said filtration system. Next chamber along contains the tanks heater (self explanatory) and a set of bio balls which, once again are a part of the filtration system. 3rd chamber from the left is the chamber that houses the skimmer (more of this later) and in the last chamber is the tanks pump, which is hidden and surrounded by another part of the filtration system, the filter sponges. From the top of this chamber protrudes an air pipe with an adjusting cap on the end of it. This pipe allows adjustment for the air intake for the tanks skimmer. Now, call this a design fault if you will, but this air pipe hangs loose inside the tank. My first 'tip' would be to undo (using a small screwdriver) the clamp that holds the tanks cables from the heater and the pump, place the air pipe in the same recess as these cables and reclamp them back up. This allows the air pipe to hang outside the tankwithout getting trapped and also allows for easier access and adjustment.
As mentioned earlier I now return to the tanks skimmer system. When the tank is first set up and switched on the skimmer system will continually pump thousands of tiny air bubbles into the tank and fill the new owners mind with panic! Fear not, this is an easily overcome problem. The problem occurs due to the fact that there is nothing for the skimmer to extract from the water at this early stage. On a large independant skimmer, used on bigger tanks, this problem is adjustable...not the case with the Orca. So here is my second 'tip'.I would recommend that the skimmer air intake valve is fully closed thus not allowing any air to be sucked through and into the tank. I would estimate it would take anything between 3-7 days of tank cycling for the conditions to allow successful 'skimming' with the Orca system, in the meantime place some fine filter wool into the same chamber as the ceramic noodles (the return chamber)this will capture any particles that get through the tanks filter system and prevent them from re-entering the tank. The filter wool should be FINE and not placed in there in a 'thick' wodge as this will only serve to slow down the waters return to the main tank and cause the back chambers to overflow. The filter wool should be rinsed out daily to remove any debris. After a few days (just keep experimenting with the air intake valve to see if the bubbles remain)the bubbles should dissapear and the skimmer sytem should kick in nicely!
The second design fault (IMO) with the Orca is the 'lack' of power in the water returning to the tank from the pump. Firstly (tip 3) ensure that the vents inside the tank, in front of the pump chamber, are fully open, thus allowing maximum throughput through the pump. Secondly ensure that the spray bar pertruding from the return chamber should be turned to face upwards so that the returning water will break the water surface thus improving airation and water movement (the water level should be set just above the spray bar)It is at this point you will notice the 'lack' of water volume being returned and so thirdly, I would recommend the purchase of a small powerhead to increase the circulation in the tank. This will be very useful for people that plan to have LR in thier tank as circulation will be key.
My last tip for this tanks set up is to attach the small power pack (with the red light on it)to the top outside of the tank, via its attached suckers. This forms a loop in the power packs wire, thus preventing any water that may get splashed onto the wires from entering the pack itself.

 Re: Orca
I found the comment very useful which i will take on board when i set up my orca soon. I have a question if anyone can help. I am not familiar with this type of protein skimmer as i had a red sea hang on skimmer, but looking inside to check i notice there is a gap about 1 inches from the top of the protein skimmer to the box that collect the organic waste. why? is'nt that might cause the bubbles to get into the tank. i thought it should acually fitted to the underside of the box if u know what i mean so the micro-bubble is aiming for it and u can controll it byt the screw

 Stonecold's article on Orca TL-450
Delighted to find this article - couldn't believe our luck, it was a lifesaver! Purchased one yesterday and were quite baffled by lack of instructions. Tank is now set up and running but obviously wont be stocked for 3-4 weeks. Can you further advise, please, what should the heating rod be set at? Many thanks.

 Re: Stonecold's article on Orca TL-450
Fantastic article Stonecold, found it really helpful. I've just bougt a TL-450. I'm gonna begin setting it up next week.

I noticed that you didn't mention the UV sterilization unit, where abouts is that?

Thanks in advance

EDIT: It's ok, I've found out - it's integrated into the pump

 Re: Article
Good article and a great help. Question, my instructions talk about an activated charcoal filter. Anybody give me a clue as to where that is?
TIA

 Re: Setting up the Orca TL-450
Just setting up TL.450 and found your article a great help. First shot at marine fishkeeping and want to make sure I get it right. Didnt come with any bio balls in the heater chamber. Do I need to buy some at the risk of sounding dumb!!! Sand and water in,filters running, so far so good. LR next. Any advice would be great.

 Re: Setting up the Orca TL-450
Hey all, i also have a ORCA TL-450 and the instructions recieved are abysmal,....excuse me for the spelling, but its a good little machine really it does alot of the work for you, i first started with RO water just to run it through, had some major noob mistakes, for e.g. added the 'live sand' to just RO water then added the salt about a week later....pfft, anyways i left this for about a week, constantly checked on forums to make sure everything was ok, in response to that microbubble problem, it seems you encountered the same thing i did its basically coming from that protein skimmer, because the tank is new there not a lot for the skimmer to do, so for some reason produces these bubbles, anyways turn tht off for a couple of days clear the tank glass with whatever you want i use a jay cloth on mine, so now its umm.....3 months down the line maybe 4 ive been quite patient, i have 5kg of live rock i did have 3 hermits but only one little baby one remains now which is quite irritating but oh well, and have kept 2 lovely little ocerlaris perculas, in there as well, as for adding snails i shall be doing this sometime next week, so i should stop the algal blooms tht keep apperearing, the clownfish are fine and all readings are low, ammonia is a little above 0 nothing to worry about greatly and everything is fine though strangely i have only done about 3 water changes with tap water pre mixed with salt and everything still is fine, the clownfish have even shown signs of dominance, with a larger female being quite obvious and the smaller male doing the 'waggle dance' id appreciate any advise given on matters including the use of kehiem balls, as a bio filtration as well as some bio balls and sponge filters.

hope this helps to ORCA users alike, and on a another note with the addition of so much filter i was thinking more fish would be in order, i was thinking maybe a royal grammar, a clean up crew and maybe another fish....not all at once ill get the clean up crew first

 Re: Setting up the Orca TL-450
This guide was very useful when setting up my tank. I have now set up this aquarium for freshwater. Maybe a stupid question, but this tank comes with 4 power cables. Looks like 1 is for light and fan, 1 is for water heater, 1 is for the pump, but what is the last one for (the one with a small red light when it's connected)? I have tried to take out the power, but it looks like nothing happens.

Second thing I have, is that the water is very hot. It went up to 28 when I had the heater on 25. Is the heater so unrelayable? I have turned it down to 22 now.

For oxygen to the water, do I need to use skimmer even for fresh water aquarium? Or is it enough with just having sirculation on top of the water?
