depends on your fauna

if u plan to use RO/distilled water (RO anddistilled water are totally different), need to find constant source for that, also u will need some supplement to bring up the GH/KH and adjust the PH too (dun ever use PH up/down chemical products)

for my tank, i refill with distilled water (0GH) and weekly water change with tap water(3GH) + mineral plus to bring up GH

i dun recommend to top up with tap water, your GH will slowly build up until its too high then suddenly ur fish/shrimp dying...
p/s: our tap water originally come with 2-3GH (depends on location)

if u keeping fish only, GH not that important, focus on PH should be fine

o0o0o0o0... no wonder my shrimp dissappear... i always keep on topup with tap water... how to control the gh kh then?

bro..i dun received email yet..><
can help me? ramon5254 at live dot com
thank..^^

hmmm.. there are few factors why shrimp will die actually.. hehee.. high GH is one of them

refill
when your tank water evaporate, only h2o dissapear, minerals such as calcium, mag will still be in ur water(they are too heavy to evaporate),
and imagine u refill with tap water (which already have mineral in it), eventually u are adding more mineral into your tank, now your tank is original mineral + new mineral from tap water refill

water change
but its okie to change water with tap water (adjust if too low or too high), because u are taking out X amount of water+mineral, and put back same X amount.

check online for the perfect GH range of your shrimp

so its better to get a GH test kit before its too late

so far i only test PH and GH, KH not really that important specially if u have 2feet tank and above, just my personal opinion and experience

Did some 'adjustment' on the plants....different look from my previous setup....

i want, i want...PM me your account number...

nice..may i knw hw much u buy the fan?..^^

i think about 80 or 90....cheaper if u can diy

Ask weijie can get more cheaper

my tank kena bba now

2 days ago i did not switch on the light for more than 12 hours. my rotola which is quite covered with hair like moss melted

i read cause of bba is unstable co2. does this means when i switch off the co2 at nite considered unstable ?

hmmm.. bba could be caused by dirty filter too

i think unstable co2 is referring to the amount u supplying when u on your light, make sure its enough for your plants but not too much to kill ur fauna

light ON + little co2 = algae partying, light ON + too much co2 = fauna pengsan

co2 indicator in tank should show green or green yellowish

what about is LIGHT OFF + Co2 on?

doesnt matter... mine is 1bps for 24 hours and light on is 10am to 2pm, 4pm to 10pm

east aqua in IPC does sell eheim accessories, but came with a "nice" pricetag

....Nice Pricetag....words i don wanna hear...LOL..got 1 connector at jln pasar yesterday, but need to use another connector due to hose size, mine is 16/18...while the connectors available are for 18/22

nice plant, can tell me what's the name of the plant in the middle and left hand side?

my co2 indicator is green yellowish

in the morning the green is darker

so i increase my co2 up to point b4 my fish pengsan ?

dun think it's dirty filter coz i juz dump in a new 2213 last week

i did not rinse the media too...so far ok no cloudy water as someone experienced

i think by increasing your Co2 level, it might kill your fish..found the reason of my cloudy water, the bacter ball.. will wait for a few days, hope to have the crystal clear as before, or any chemical would might help to make it clear faster..
