Reddit reviews Hydor Koralia Nano 240 Aquarium Circulation Pump, 240 GPH

Welcome to a hobby that's as addictive as crack and sometimes more expensive.

1. That's not a skimmer, that's a filter. Skimmers work by producing tiny bubbles of air which trap organic matter in the water tension of the bubble and carry it away. People refer to those as HOB filters (Hang On Back). What you might want to look into is a HOB protein skimmer like this one: http://www.marineandreef.com/CPR_Bak_Pak_2_Bio_Cyclone_Bak_Pak_Skimmer_Reef_p/RCPR02072.htm?gclid=CP_2y73u-7gCFSU6QgodZmcADg
   
   
2. If you decide to go with a filter and not a skimmer, I'd look into ones that do surface skimming like this one:http://www.amazon.com/AquaTop-Hang-On-Filter-Surface-Skimmer/dp/B005DCCT04/ref=sr_1_5?s=pet-supplies&ie=UTF8&qid=1376446396&sr=1-5&keywords=hob+skimmer
   The reason you want "surface skimming" is because proteins tend to build up into a film on the surface of the water. This film reduces oxygen exchange and can be harmful to small fish.
   
   
3. That powerhead is WAY to large for a 10g. The rule of thumb for saltwater tanks is 20 times more flow than volume. So for a 10g tank, I'd get a 240GPH power head. I'm a huge fan of the Korali Nano: http://www.amazon.com/Hydor-Koralia-Nano-Aquarium-Circulation/dp/B0036S4YZ0/ref=sr_1_1?s=pet-supplies&ie=UTF8&qid=1376446665&sr=1-1&keywords=koralia+nano
   
   
4. The more filtration the better. I don't think I've ever seen any setup that has "too much" filtration. I know that technically it is possible, I just have never seen one. Live rock and Cheato are both types of biological filtration, while floss is physical. The worst thing that can happen if you have too much filtration is you'll have to do water changes less frequently.
   
   Good luck and let us know what you come up with.
   
   EDIT: removed bad advice.

10 gal is fine. I started my first SW tank a couple months ago and I got a 6 gal. Now, you will have to have to have live rock. Without it, it will be nearly impossible to have a stable tank. I suggest you get around 15 pounds. Get all the live rock you plan to have in you tank at once so your parameters don't get an ammonia spike if you have a fish inside. Aragonite sand should be fine. I would stay FOWLR (fish only with live rock) because corals are much harder. The cycle is also very similar. Set up your tank, add sand, fill with a few inches of water, add rocks and aquascape, fill up with water, add a deli shrimp, and you should be good to go. You will need some salt, a hydrometer, a good reliable heater, some lighting, a power head and test kit. And also a filter.
This is what I would get

I would put the bio rings and carbon aside and replace with this,

Add the matrix when you start cycling, then add the purigen when you are getting fish. The reviews are speaking for the product. Purigen is simply a godsend
http://amzn.com/B00019JOSO
Go for a refractometer if you can afford it but this works fine for me as long as I tap it an there are no bubbles.
http://amzn.com/B001EUE808
The test kit.
http://amzn.com/B0036S4YZ0
This powerhead should do fine in a 10 gallon.
http://amzn.com/B003M7P9YU
This is one of the best most reliable heaters on the market. Many will fail and bake your tank but not the jagar.
http://amzn.com/B003EE5GUS
These make life a whole lot easier BN testing water or adding things like calcium. You get 10 so they should def last a while.
http://amzn.com/B008SJ1H7A
Get like 5 of these. They are extremely accurate and last around 3 months each. Wrap the wire around the tank and have one on at all times. They also help when doing water changes. You should also pick up an extra heater for water changes, via aqua and aqua top have good ones. These are made in china and sent out to companies like coralife to be package and sold for like 10 dollars, see

Now, this is the salt I use for water changes,
http://amzn.com/B0002DJU0G
This should last you a year or two and is way cheaper then continually buying salt. I personally use tap water that has been heavily decholinated with this,
http://amzn.com/B00176CVK8
You should get your tap water tested for copper which can kill invertebrates. A 5 gallon bucket is really useful as is this siphon for water changes,
http://amzn.com/B002LL8BWU
This net is really fine and will catch most tiny debris
http://amzn.com/B008HPOCUE
You will probably find it cheaper in a store. I leave it in front of my powerhead for a hour or two every couple to days to catch debris and waste.
These tweezers help for when you don't want to get your hands wet.

But they do start rusting after a lot of
use.

This has been the best fish food in my experience but all fish should be fed a varied diet. This is a good staple and should be substituted with brine shrimp, mysis shrimp (frozen) and seaweed.
Not everything here is necessary, I'm just telling you what helped me make the jump to saltwater.
Here are some pics of my tank:

One last thing, in a tank that size, draw a small line where you want you water level to be, when it goes below that due to evaporation, top off water. Test your salinity often in that tank. I use seachem marine buffer to deal with pH issues but chemicals and buffets should be avoided.

I think this is the link you are looking for ;)

one of the best setups I've ever seen had roughly 5-6 500+gallon tanks.. beautifully colored and amazing corals. The guy sells them and grows them for research.

I asked him what lighting he was using.. expecting him to say some god awefully expensive lights.

He told me to buy this granted, the auction is done, but search the same thing... its very affordable and very powerful.

I did not have room to hang it from above, so I opted to get THIS instead. It works pretty awesome. everything is growing nicely, but if I were to do it again, maybe a more powerful one.


also, having bought about 5 different circulation pumps for my 20g. some loud, some suck, some are huge.. don't waste your time, just go for this I found it to be the best.. super quiet and magnetic

Hydor koralia nano 240gph. In the 10g I had it in it was a little strong, but in the 29g it's a perfect. I don't think it would have a problem in your tank though

Yeah maybe! I have a small 10 gallon tank right now, with the hipargero lights and this fan that I will be installing today: https://www.amazon.com/gp/product/B0036S4YZ0?ref=ppx_pt2_dt_b_prod_image.

I also have a GSP in there that is flourishing. I'm still figuring out the lighting settings and everything but I moved the coral to the farthest edge that I could. Maybe the water pump will help with algae settling on the coral.

I hate airstones with an ever loving passion and I never use them in any of my tanks. As long as the filter provides some surface agitation you are fine without them.


If you want better circulation get a pump like this

You can try this https://www.amazon.ca/Hydor-Koralia-Nano-Aquarium-Circulation/dp/B0036S4YZ0/ref=sr_1_8?s=pet-supplies&ie=UTF8&qid=1468459442&sr=1-8


Try to angle everything so it moves everything in as close to a circle as possible. It should help.


Also, why the root thing?

Remember, turtles aren't really playing. They can turn on each other very quickly, esp being that cramped up. Try to find a tank on kijiji or craigslist. If you get a 90gal or bigger, you don't need 2 tanks. You only need 2 basking spots. Use egg crate found at a Home Depot type of store. its found in the lighting section. Cut it too big and slowly chip away at it until you can force it between the glass. It allows water flow so you only have the 1 tank to manage.


When buying used, don't pay more then $1 a gallon or not much more. Thats all its worth at most. If you find a cheap old tank, make sure to reseal it (its soooooooooooooooooo easy!!!!!). Before the rescue I bought a 90gal+stand for $90. Resealed it and that sucker lasted me for years :)

I was battling hair algae in my 20long and loosing, mostly in part because of running a sponge filter and having dead zones. Deep cleaned and added this powerhead, now I can visibly see the algae die off. I think the 240g perfect flow for a 20long with tetras.

How to vacuum/clean the gravel of a heavily planted tank, like a carpet or really thick bush? I was thinking of using a circulation pump to kick up any debris into the water column. Was curious if anyone here had any input.

Lots of good advice in this thread. If I could add my 2 cents. I will occasionally make a liquid food mix with some shrimp powder and do a direct feeding with a feeding tube. In my 20G tank I've got a circulation pump to keep the flow rate up for it, but that might be a bit much in your 10G.

2 of these, 2 of these.

no dead spots. just enough water movement. crystal clear water.

Would an aquarium circulation pump work?

As for the temp, why not plug the fish tank heater into an STC 1000?

To start with, a canister and a sump together are overkill for a tank that size. Overkill isn't really a bad thing when it comes to filtration.

Your diagram makes sense, and your plan seems fine. If you haven't yet, check out this post about sumps in general, but it seems to me like you have the concepts in hand.

I'm guessing that you mean surface skimmer/overflow in your diagram where you have "skimmer/intake" listed. Freshwater does not need protein skimmers, they don't work in any way as effectively as in saltwater.

You don't need to hook the return (what you call outflow) to another powerhead, you can just use a U-pipe to flow into the tank.

What you'll want instead of another powerhead, if you find you want more flow, is a circulation pump or two to move your water around.

Let me know if I misunderstood you or if you have any more questions

Yeah I do have it pointed to the top, but it seems a bit underpowered. What would you recommend? I was looking at this Also a local guy gave me a bottle of start smart saltwater aquarium instant cycler... Do you recommend that or should I just wait it out.
