hmm nice to have a new enthusiast. water change is necessary. it is unavoidable unless you want your fish floating upside down aquariums are not like the normal environment where you have fresh water from rain and river flowing into lakes, seas and what nots. aquarium is a closed environment. unless you have a heavily planted tank and few fishes, water change have to be done quite frequent loh.



brother nezu.......30% per month arh??some forumner suggest 20%-50% weekly leh...........my puny tank is 1.5 feet length, 7 inch in width and 11.5 inch in height.pics already taken now looking for card reader for my camera card so that i could upload and get some comments hehe

but to be really safe get a test kit and to test on water quality regularly so you know when you should change.

well i usually change water once a week around 25%. usually i look at the water and see if its cloudy?are there weird smells?water slightly yellowish in color? it's just some guide not a definite rule nezu. some dudes in the forum suggest 25% to 50% weekly water changes, searched around on the net also the same. but the lfs at my place said no need to change water weekly........so the best method i think is to get a test kit. test regularly maybe few days once so that is quite a good indicator when the water quality is deteriorating and you can change the water...i read also for some they do daily water changes........ its up to you. so far been doing weekly changes and my plants, fish are in good condition. no need to do until 50% lah coz the changes in water like ph might coz a lot of problem. i think 25% per week is ok already.

don't scoop the water out it would cause alot of ermmm turbulence in the water. use a plastic pipe to siphon the water out. also dun just pour the water in. it would cause alot or turbulence as well. the turbulence would change your aquascape if its too strong sumore your fish later siphon the water back in from a clean pail. here's how i usally change my fish tank water. get an empty pail place it lower than the tank siphon water out. clean pail put in fresh water add some anti chlorice according to guide. place pail higher than tank either on chair or something to support and siphon it into the aquarium. minimal damage to your aquascape


crayfish can grow quite large and i think they might destroy your plants.....i've no idea as i've never kept crayfish as pets before. not flexiglass dude its plexiglass or acrylic. read from the net that if you're placing the tank on a stand make sure that there are support for the entire area of the bottom of your tank if not the plexi will crack. glass tanks are more durable but plexi is lighter.

HOB filter are those filter that you hang onto the side of the aquarium

nezu......some plants cannot survive in low temperature..................i've checked and most plants lowest temp is 24 some can tolerate up to 28 or 30. a lfs boss told me that algae are more likely to bloom when temp is 30 and above

cold fusion:

co2 needs to be turned on when there is light. plants needs both light and co2 for photosynthesis. if u turn on co2 at night with your lights off you're wasting money.
