No worries bro. Yeah, basically we don't wanna disrupt the beneficial bacteria inside the biological filter. In my experience, I found it safe enough to wash the sponge (the one at the filter intake) with tap water. But be sure to NOT let the media out too long it may dry up and kill all those precious little thing
Oh if you wanna be sure, you can also use dechlorinator or conditioner on tap water to give you the extra safe water for cleaning the filter.

Setup a new planted tank substrate. Good read by Francis Xavier. I been reading his post since yesterday at plantedtank forum. Maybe weijie bro can include in first page with substrate post Francis Xavier explains carefully why we use each element (5 element) and how much to use.

i'm thinking of replacing the glosso in my nano tank with other foreground plant.

failed to make the glosso carpet nicely make me really stress.

but i dont want to invest more money on light. 16w is enough already for my nano tank..

any suggestion?
about those hair grass, they really need high light??

Japanese dwarf hairgrass need cold water below 27*c mine in my 4ft seems not growing hahaha too hot... Glosso will grow maybee you try to pump in more co2... it some how works for me

fish no harm , plant just get dirty, shrimps may suffer.
Get one 11L mineral water to store dechlorinated water for tank topup and wash your stuff(filter etc).
Put some filter floss near the hob outlet , will trap most fine debris, throw and replace new one everytime you clean filter,
the used floss can be use to seed your new eheim 2217 with bacteria in the future.

Since you already have a running tank, you should now seed some filter media for your new 4ft tank, this will reduce
the new tank cycling time significantly.
You can use a small internal breeding tank, put some new filter media and arrange it under the HOB water outlet.
When you ready to setup the new tank , transfer the seeded media to your filter or just move the whole breeding tank to your new tank, put it under the filter output outlet.

Hello arrow bro

One of my fish look sad plus weak. Maybe because the water I put in not dechlorinated in big amount. Usually I put tap water inside they also fine. But now I know, next time keep a big bottle of declhorinated. But keeping this aged water, I thought should provide aeration also.

Hmm Okok, next time I will use a filter floss, I always thought want to try DIY a sponge at the outloet of HOB but don't know how do it. Hmm, your idea use filter media put in interna breeding tank very good! I will absolutely do that

Only get those internal breeding tank with SUCTION CUP, size vary depend on your tank.
I use this (refer picture) for my 40cm tank water top-up , new filter media seeding,
nitrate sucking plant sanctuary, temporary shrimps refuge camp, during new tank setup(pouring in of water [Throw away those dirty soil plastic bag].


Move the breeding tank up and down to adjust/minimize the flow of water to the soil.

What you mean with this "Maybe because the water I put in not dechlorinated in big amount. Usually I put tap water inside they also fine. ?? Don't play play with water, ALWAYS use dechlorinated water, you run the risk of killing all the good bacteria in your tank/filter.
And during new tank setup when you put ADA 5 elements - Bacter 100 under the substrate, you just render it useless by pouring in UN-dechlorinated water which kill all the dormant Bacter 100 bacteria.

Whose the one sell?

thx for the info sifu arrow...

blue grass aquatic..
you can find him in FB and also pet store

Thanks

Anyone use those commercial hang-on Cooling Fan before? Is it really that effective, or it just the same as a DIY dc fan ?

AI also selling borneo sucker, bro flipmode and sang gemok both bought 4 each . price quite cheap less than rm5 per tail.

Can I ask how determine dechlorinated water!!! Killing bacteria scared me! Dechlorinated is take tap water put somewhere else + anti-chlorine ocrrect? I only have 1rm bottle aquadine. Can recommend a good quality to me? arrow can give guide how to prepare the water? I never though of this.

I prepare by putting anti~chlorine into big mineral bottle 11L with tap water, left it overnight, but sometime I use it straight away. , no harm so far.
I use seachem prime(cheaper in long run) though you paid more first around rm45 for 250ml, lot of ppl using nutrafin, so you can try that as well. Dont use API stress coat,it leave a slime white smelly coat at the bottom my mineral bottle.
you only have 2 tank, buy a better antichlorine can last very long,
use your rm1 aquadine for your guppy tank. and get 2 big big mineral bottle.

i saw in japan aquarium shop, no cooling fan, it was 28c. on the comparison side, cooling fan on same size aquarium, its 26c. 2c difference. the aquarium is nano 1ft type.

Added on August 2, 2012, 3:51 pmfor those with small aquarium ie nano tanks, u can actually put an inverted (upside down) 1 liter bottle like our coca-cola bottle and it will auto top up as the water reduces. some scientific term to it.. but it works! i may try it on my 4ft tank.. haha

jctasoga:

what is the ambient temperature? it is highly affect the performance of cooling fan.

yeps thats another alternative for auto-top. but for sure it wouldnt look nice if you have a coca-cola bottle on top of your nano tank.

can you draw some diagram for that?

long holidays is coming.. you maybe can patent it and claim your royalty...

I use the ac fan 120mm x120mm the size

i miss alot of spams these days...
company wont let me excess the forums..what did i miss?

how effective it was, it said able to drop down til 4c max
