Hi all, i'm planning to get a either a 5x2.5x2.5 or 6x2.5x2.5 tank to house maybe 3 or 5 red. Just wondering what the proper liter /hour pump that i should be looking for? Gonna run it on a sump.

Back to arowana after 25 years.

Sharing my new red.

Thanks!

Some update of my red about 7 inch. On feeder fish + shrimp diet.

Thanks for the heads up, she's a picky one, does not take sw and mp ...I do quarantine and treat those feeder with malacite green + yellow powder few days before offering them to my aro.

Btw ,just wondering do u guys practice gut loading? Such as feeding those feeder with high quality pallet before givin it to aro.

Dinner time bump. About 9 inch plus now.

hi bro, just sharing my aro development after 6 month of keeping from 7 incher to a 13+

Color just started to show last month, however it's just pale orange color spread on cheek and scale.
Vid below taken while tanning with xl led light, no idea why its show pink in the video, on naked eye, everything looks white except the fish .

Yes, it's abit to small, I'm actually quite surprise that she able to grow to this 13+ size in a 2.5 ft tank

Anyway,most likely by end of the month will get a cheap 4x18"x18 or 422 to temporary house this fella until I settle with my other house.

Based on my understanding...

top filter or canister
No degassing, means oxygen exchange solely rely form saturated o2 available from your tank water. Requires aerator to promote aerobic bacteria growth and fish well being. When O2 not sufficient bacteria colony may got wipe out... hence the cloudy water syndrome when ever fresh tap water are introduce to tank during water change, sick fish, not to forget a acid generator if pre-filter are not clean periodically.

Trickle filter.
Provide some form of degassing, C02 are strip when water drip on medias, however it's subject to how the trickle box are design. If it's fully enclose then back to square one, a CO2 reactor. A properly design trickle box require a lot of ventilation. Another concept can be put to use is to have a fan sucking air out from bottom to top for promoting active O2 exchange, such type is known as counter air flow trickle. It introduce load of O2 on water which is beneficial to fish and bacteria colony. (I'm building one for my upcoming tank )

Old school sump, pretty much similar to top filter / canister if it's enclosed inside cabinet. The advantage is,
1) Space for load of peripherals, such as UV-C light, heater and etc.
2) Able to accommodate load of medias
3) Spot with very slow water flow or dead spot for anaerobic bacteria growth to keep nitrate in check.

Im still waitting my tank set + sump to be delivered before i can start to work on the trickle filter. My design something like a tall cube with vent hole below ,fan pulling air out from top of cube, also will be using a drip plate instead... Not gonna use drip pipe as it tend to clogs in low preasure return.

ouch the highlighted portion is your root cause.

1) scrub alge = your intention .. understand.
2) filtration off = When you scrub algae it cause the water to be full with fine particles which may degrade oxygen absorption from gill. Never turn off all your filtration while you are scrubbing. You have mechanical filter to filter out particle right ? use it, white wool media cost like RM2 per pack no ? It could cause ammonia spike as well.. pretty much a disaster in making.
3) half an hour =without any sort of pump /filter to maintain saturate oxygen, leaving your aro there with filthy water without any sort of oxygenation. Smaller tank are not that forgiving when it comes to dissolve oxygen not to forget you just scrub ya tank.
4) add new tap water = Your aro fate is seal here. Tap water practically have 0mg of dissolve oxygen. Chlorine further stress it out, Anti chlorine is not magic potion, it need time to works, it can be further enhance by aeration via power head or air pump. You may do more then 30% if you have aged oxygenated water. If you don't have aged water, use power head, modify power head to produce very fine / micro bubble, this will introduce more oxygen and assist to remove chlorine compound at a much faster rate.

Width or deep minimum 2.5 ft for aro as suggested by most of our brothers here.

Go for sump, canister not gonna make it with such water volume. Example a 7x2x2 thats about 792 liter of water. Turn over rate for pump many may recommend minimum 10 time an hour which is a 7k lph pump. However slower flow pump may be more efficient as water stay in sump longer for bacteria to break down waste. If u had a smaller sump , you may want to start with a 4-6 times turn over an hour pump as starting point.

3. Lets talks about filtration medias. Do not ever fully loaded a compartment with corals unless u keep those cichlid type fish.. coral should be used sparingly as buffer. One or two cup is good enough to act as buffering agent for a period of time. Coral may hav bleach on it and dormant virus or pest. Wash it with tap water and follow up by rinsing it with boiling water before using. In general soft water is prefered for aro.

Its all about surface area, get those high surface area ceramic tubes/ bacteria house/ lava rock, sintered glass ring, ceramic ring, ceramic bead. You might want to skip those fancy moving bed k1 medias ...its pratically useless in a 1.5L coke bottle, effective surface area 500 sq meter for 1000 liter of k1. That amount of media alone require a 2000 liter sump to work. Mt lotus root have about 1.1k m2 surface area per pcs with a very small foot print.

The more the better? Well more media not necessary bad, there's actually journals on surface area calculation based on feeding rate. But hey, as a hobbiest we always want more lol.

Compartment 1 mechanical, 2nd compartment any high surface area media is good enough. 3rd compartment i usually like to jam pack it with smaller sized media to promote anerobic bacteria.

Incase u had a small sump, may want to look into a secondary pump to divert water from 4th compartment back to 2nd compartment or a bypass piping from main return pump.

Happy aro keeping.

I hav 4 pcs of them running on my 2.5ft aro tank, crystal clear water but not sure its biohome at work or mt...

I had high hope on mt on my new 4x2x2. Tank just delivered yesterday, cycling now with 24 pcs seeded mt lotus root, more comming in once my final sump are delivered.




Attached thumbnail(s)

Mt material pretty solid , wont crumble easily like those cheap rm 2 bio rod. Those cheap rod.. no need to wait for years... after 2 week of usage it feels soft and crumble on its own.

I did have k1, was recommended by a friend 4-5 years ago, but i use it as trickle filter media for my 100L gold fish tub. Been running it wet dry for years, quite ok. Crystal clear water as well.

Went out buy blackwater extract ...end up tah pau a goldie lol.
5 incher, eat pallet.
However no high expectation on such normal grade aro, but will try to groom like how i groom my red

White tank all the way till it reach 15 inch or more. I personally dont favor those heavy base color aro, they look 'dirty' to me. Lol.
First time raising a golden though, no idea it will show pearlies or not, this piece gonna be my experiment & study purpose.

such a beauty, nice catch bro.

how i wish my cheap MG could turn out at least lvl6 cross just like urs ...

hi bros,
Sharing my tanning journey of my red, 3 month plus on florescent type lights since early July 2020. Hope she'll get red before 2021 CNY

Currently on a 4x2x2 tank. I'll wait till it get 20-22 inch first before i'll moving her to a new tank. No rush at the moment she's just 16 inch
As for tanning light, i'm using 2 unit of aro-10 to "grill" her.
