Why I created the OPEN BOTTOM TANK ???? Taking away the stress of maintaining your aquarium will bring back the enjoyment that fish keeping once brought you. THE OPEN BOTTOM TANK Advantages ) No more splashing salt water out from tank to mess up surrounding area 2) Water evaporation cause by air pump reduced by 100% 3) Waterfall can be constructed inside tank to create a stronger current 4) Air flow can be increased as bubbling air ONLY rise into top tank. All dried salt will fall back into tank. 5) Free movement for fish to navigate between top and bottom tank 6) Hiding space at bottom tank for the smaller fish. More coral can be added into lower tank 7) Dead fish if any can be easily removed from the bottom opening outlet without having to remove coral to reach them
No fear on over flow filter as box filter is constructed inside lower tank 9) Replacement or cleaning of sponge in box filter can be easily removed in the lower tank 10) Changing of water in top tank is not require 11) Cut down cost on salt due to NO splasing water droplet cause by airpump, as air stone usually create air bubble that will mess up the exterior of the fish tank with salt. 12) Very suitable for those busy people who have no time at all to maintain their tank yet love to keep one at home 13) Waterpump will NOT run dry when partial change of water is in progress 14) Easy to maintain 15) Simplified Suggestions from viewer is most welcome to further improve this aquarium set-up. * Water is not …

FISH TANK OPEN BOTTOM

WHY AN OPEN BOTTOM TANK ? Very suitable for those busy people who have no time at all to maintain their tank yet love to keep one at home Submersible biological filter in lower tank helps to maintain clear water. Water change and massive cleaning is minimized. Cleaning is also make simple. Partial change of water and removing of dirt particle, if require, is carried out in the lower tank that include feeding. All rocks and plants in top tank are placed 12cm above bottom tank to allow easy access should siphoning of dirt is needed. Rocks need not have to be removed while cleaning is in progress. Water current in top tank is activated by air pump. Fish able to move from bottom tank to top tank without restriction. Mini waterfall in lower tank is to provide extra oxygenation of the water. The open bottom design allows replacement of plants and decoration as often as you like. BUYING NEW FISH Fish aren’t exactly the expensive sort. They don’t wag their tails or purr, so it’s really hard to tell if and when they are happy or sad. But they do have feelings and can feel stressed, just like us.

So never buy a fish just because it strikes your fancy while you are out “window shopping” at the aquarium outlets. If you intend to acquire new fish for your aquarium, do a little of homework before you go shopping, so you can provide a suitable home for your …
