diy aquaponics system | Fixing Eheim 2217 Rattle Noise

diy aquaponics system

After years in service (15 plus years), my trusty Eheim 2217 finally acting up. For the pass couple of days it produced loud rattle noise. I dismantle the filter, especially the impeller area and found that the shaft rubber cap was loosen due to wear and tear as well as age. This cause the impeller to miss align and after thousand or maybe million rotation, the shaft hole is giving up and become ellipse. This is where the noise coming from. The impeller was hitting the wall during rotation.

Picture of the shaft where one of the rubber cap is loose.

Impeller picture where the hole become ellipse due to continuous friction with the shaft.

Zoom in on the hole, colored in red for easy viewing.

So I replace the whole assembly, bought new impeller and shaft which cost me total S$37 (S$29 + S$8) and it silent like brand new. My advice next time when you service your filter and feel that the shaft is loose, change it.

diy aquaponics aquarium | Boyu CD 01 inline CO2 diffuser

diy aquaponics aquarium

I just bought Boyu inline CO2 diffuser. It can be use inside and outside tank. Just take out the strainer if you want to use it outside the tank. I heard it is very efficient and maintenance free. Not sure how true it is. My guess is brown algae probably will grow inside after a while.

I bought 2 of them from ebay, since none of the local fish shop carry this product. They do have similar product from ISTA but very expensive $27. It cost me S$8.60 for 2 but the delivery charges is S$11.90 which is more expensive than the product. The stamp duty on the mail is only HK$19.1 or S$3.75. Nevertheless, it is still cheaper than ISTA.

I like this product. For starter, it does not reduce the filter flow. Furthermore, I not need to worry about green spot algae. Probably because it is inside cabinet thus no light. However, after a while I can see some brown thing build up (diatome?). It is the same build up that normally hapen inside filter hose. Nothing to be worry about just use brush and clean it during regular filter maintenace. It is much easier to clean compare to green spot algae.

diy aquaponics toteponics | Cheater at AGA 2011 competition spotted

diy aquaponics toteponics

AGA International Aquascaping Contest 2011 result was anouced last week and my tank "Lost" happen to be in 2nd place in 120-200L. However to my surprise the 1st place goes to IAPLC 2011 rank #14. It is a great scape, no doubth about it but according to the tank size written on the IAPLC booklet, it is 120x55x50cm tank which is 300L or 87.177 US gallons. How could the tank of that size competing in 120-200L category? I checked the AGA entry details and it was written 100x45x40cm which is 180L or 47.551 US gallons. Someone was obviously cheating. He reduce the tank size so that he can compete on smaller category (maybe he want to be in different category as Cliff Hui) or to have better depth. Imagine 300L tank submited as 180L, reported almost half.

The holy-grail of aquascaping is to make small tank look big. What the easy way to do that? Declare big tank as small tank. Imagine what would hapeen if I declare my 90x45x45cm tank as 30x15x15cm tank? Every one will amaze ont he depth that I create on that tiny little tank.

I have reported this issue to AGA but they dont seem to be eager to disqualify it.
