MT got Gen 1, 2 & 3. Improvement to the surface areas come with a price. I saw ppl buying truck load of MT for their koi ponds. Must have cost a fortune !
I'm using Taiwan GAE bio ball. Plenty of bootleg version out there.
Any good recommendation for mechanical filter on compartment 1 ?

Hi guys, need advice as i will be upgrading my 4ft tank to 6ft. currently im using the canister filter, and my new tank will be using sump. i have ordered some biomedia like seachem matrix and i still have some leftover biorings (bout 2L) , so my question is can i just put them in a big mesh bag and soak inside my 4ft aquarium to build good bacteria in it while waiting for my new aquarium to reach? I currently have a pig nose turtle and 1 small arowana.

Hi Sifus,

just want to get your opinion. i bough a 6inch Aro on March. i kept it in small aquarium. on May i bought a 3x1.5x1.5 aquarium and transferred the Aro. it was floating tail up for a day and then became normal. end of may i bought Dophin cf1400 and water quality became clear. i then start to change water about 30% every week and i will put some salt and 15ml of nutrafin and all went well. on 13th Jun i changed water same way then after a few days i saw there was brownish color alge like growth in the aquarium. i checked local shop they said its normal and asked to wash the tank and put some pleco. so last Saturday i bought 2 small pleco, 1 baby oscar + 1 red tail . i first used sponge to wipe the brown alge and stopped my filter and air buble. water was already brownish and i let it settle down for half hour. then i pumped out about 40% of water and fill up new water from tap. then i poured nutrafin 20ml and didn't put salt . then i released all then new fish also inside with the water. after few hour saw my ARO slow swim on top only with his mouth open and close. i suspected something wrong. Sunday morning i went to fish shop n they told me it could be because of chlorine  so asked me to change half water and put in anticlorin and salt. i removed the water add salt + nutrafin 20ml and add water. ARO was still like that. evening about 5 pm on same day say aro already upside down stuck on my filter but still breathing. when i try to remove it it vomited blackish substance similar to alge. i moved it to small aquarium where i used to keep small karp for feeding. then after half hour later it died. but other fish in my tank all ok.

this is when its ok.


this is the algea like brownish growth


this after 1st change water


ths is after changed to small tank



after dead its already 10inch



my wife is very sad as this is our first ARO. so she now ask to buy new 1 since the tank looked empty. im trying to find what went wrong so same thing dont repeat. please advise. already plan to buy 7x2x2 tank next week for the ARO

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

Cute little fella. Are you planning to put him in a white tank until the pearlies show?

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.

From experience there will need to be some form of human intervention to make the anal fin right again.
How much salt did u add? Maintain clean water, stop feeding and doze appropriate amount of salt will help heal the eye without much drama.

I followed the instruction on the salt package which is 6 teaspoon for every 6 gallon of water. My aquarium rank + sump filter have approximately 220 gallon water, so i added 37 teaspoon of salt.

Do you know anyone who can help to cut anal fin? I will cut it only after monitoring few weeks and it never grow back..

Ok since the salt is only effective if its the correct doze.

I do my own operations when necessary so unfortunately cannot recommend anyone. U can try asking some of the Aro specialist in town. Anal fins can be a little difficult to tackle but given time there is a 50/50 chance of healing properly.

I think the salt is working as the eye is recovered. Well, as for the anal fin...i will monitor see how it goes..

Anyone have design layout for sump filter and overflow weir? Plan to build 6x2.5x2.5ft tank with 5ft sump

Very informative video Harvin. Great job. Keep it up ! Just wondering does the overflow pipe have very loud noise ? I found few solution on Youtube but my LFS doesn't recommend it bcoz they said it will easily get clogged. They also recommend another design of sump tank as shown on the attached photo. Anyone know what's the different compare to sump tank with narrow partition?
