A 2226 for a 2ft tank is quite strong. Is it the one rated for 950l/h..?
I would install a long rainbar to reduce the current and fill the water up above the rainbar's height. If you worry about oxygen content, you should consider using an airstone.
Hi bro
I am a newbie and is cycling my tank for 3 weeks already. I am using a rain bar and eheim 2226 for my 2 feet tank. I didn't fill the water level to the rain bar height so you can imagine it is like peeing in water
My question is I realise that the evaporation rate is pretty quick hence is it necessary to use a rainbar? I know that shrimp will do better with more oxygen and so is the good bacteria.If I use a normal outflow, I scare it will cause a whirlpool. On the other hand if I fill the water level to the rainbar height, I scare the oxygen output is lesser which may affect shrimp.
Please advise. Thank you and have a pleasant day ahead

Thk for reply. Sorry I am using 2224 with a prefilter.Originally Posted by vannel
Face the rainbar at the glass instead and top up the water to cover it. As long as there are waves on the water surface, the oxygen will be able to dissolve.
You can also try drilling bigger holes in the rainbar to allow for better surface agitation without too strong of a water flow, so you won't have to face it to the glass. Then you won't need an additional airpump. You can also adjust flow rate on the outlet side using your quick connects.
An Eheim 2224 makes a lot more sense. Anyway, when you mentioned a prefilter, is it an external one? Or are you talking about the kind you put on your filter inlet?
With an external prefilter, your flowrate should be reduced. Add in the rainbar, and the flowrate should be about right. As Navanod has mentioned, if the current produced is still too high, turn the rainbar to face the glass or tilt it 45 degrees up and outwards.

Great thank to all your help
My worry is the evaporation rate. I don't want to keep topping up as it may have certain impact on water parameter unless topping up with distill water have no impact on it then I don't mind top up it. My prefilter is the external kind. Only worry is the evaporation rate. Too fast already. Is it good to have more oxygen for shrimp or make no difference? If you will me, will you prefer more oxygen or less evaporation rate?
The 1 thing that will solve your problems is an airstone! Any reason why you are not considering one?
Raise the water level to your rainbar. Then use an airstone if you want more oxygen. Both problems solved, no?

If you can afford distilled water, that is a good way to do topup. If using tapwater for topup, you have to keep an eye on GH and TDS.
Not much can be done to prevent evaporation except to reduce the temperature of the water. Incidentally, temperature and dissolved oxygen is linked. The cooler the water, the more oxygen can be dissolved in it. The cooler the water, the less evaporation too, unless you're using a fan to cool the water.
Airstone is good in the sense that it does not contribute to heat dump unless using HOF or canisters. However, alot of splashes and tiny droplets will be generated, further increasing evaporation rates as well as staining the glass with water marks.
I do agree it splashes and stains the glass, but, water stains are always going to be around. If not from the airstone, you will still get water stains where your water level is. Also, I believe the airstone will be a better option as compared to having the water below the rainbar in terms of evaporation rate.

i think water evaporation is not possible to avoid. having a chiller helps but expensive and electricity bill will also go up more if you dont mind
Thank guy!!
Air stone is like an internal filter than pump air too? Sorry for the noob question
No no.. Airstone is just a stone/wood piece that any LFS would sell for between 20c to $2 depending on what type you buy and where. You attach it to the end of an airtube which is connected to an external airpump. Airpumps can be gotten cheaply at many LFS from between $5 to $15 for a small single outlet pump. Of course, the airstone is then placed into the tank to bubble the water.

Thank bro .. I just bought a small internal filter that can be placed in the tank that can pump air while the filter can act as biological media for the extra bacteria growth .. That was what the fish shop boss told me .. Hope i was doing the right thing =)
Chansl bro, did the FS boss also include the required airpump in the purchase? Or is the air function part of the internal filter.
There's no right or wrong, at the end of the day, the aim is to circulate water and improve water quality. I think you are quite nicely covered for now
Hi,
I wanted to share a method I use whenever I use a power filter on a shrimp tank which helps prevent losses of baby shrimp to the filter.
Even if you are using the Ehiem Pre-Filter you will lose baby shrimp.
I enclose my filter intakes with a fine mesh filter media bag which is stuffed with Ehiem Ehfifix, a coarse strand, springy mechanical filtration media.
This media keeps the mesh bag fluffed out so the water intake is spread over a wide surface area and will prevent loosing baby shrimp while not impeding the filter intake flow. This works very well.
Old fish breeder. SA Dwarf Cichlids, Hypancistrus sp L260, L333 and Peckoltia L134 breeder. Also Sturisoma, Dwarf Corydoras spp, wild Discus and Killiefish. Like breeding Characins and wild Betta spp too.
Hi navanod bro, I bought a small pump to pump the air into the filter
Nice method. Thank for sharing
Interesting...I may be able to use that on my overflow intake too...thanks for the tip.
Erm, this Eheim Fix looks just like green wool/Japanese mat right?
Hi, i'm using a ehiem 2224 too! i add on a airstone and prefilter on my suction part. =)
Apistomaster, any photos to share? whatsapp me @ 91852339. Thanks.
