DIY Tubby

[kokhui]

Anyone one of you expert handymen have any experience in DIY tubby? Care to share?

IMO, not very worth it..

coral lab is selling tubby at a reasonable price..if u DIY it will cost around $50-70..top up a little more, u can get a set from coral lab already...and u dun have to worry about faulty units, dun have to go to SIM LIM to get the components, dun have to waste time making it..especially if u are not familiar with electrical components..but if u are good with it, u can try..nothing wrong with being cheapo..just like me!! hahahaha...too bad i never like to deal with electrical stuffs...

i think coral lab's tubby comes with a warranty also, but dunno how long...

do a search loh.. I made a DIY tubby even before the tubby started being produced for sale... even uploaded the schematics of it and costs etc etc...

not to mention the risks involved... I got electric shocked twice because of stupidity...

IMO, not worth the trouble... but if u on ultra tight budget like myself can give it a wack if you are willing to accept the risks involved...

BTW, my DIY auto-top up been working for >1year liao no problems so far...

hehe...

my DIYed "tubby" must be the most cheapo ard...

wat i use is a jerry can, an air pump and a digital timer.

below are the steps involved.

1)drilled 2 small holes on the cap of the jerry can. The holes must be small enough for the air pump tubes to go through only and not leave any space for air to escape from the jerry can.

2)fill the jerry can up to 3/4 full.

3)connect one tube from the air pump to the jerry can, make sure the tube is above the water level in the jerry can.

4)connect another tube from the jerry can to your sump/main tank. This tube must be submerged in water,all the way to the bottom.

5)connect the air pump to a digital timer(you can use the analog timer here,but because the analog timer has only 15 minutes block,that why i prefer the digital timer)

6)check how much water evaporates from your tank daily, and adjust the timer accordingly. i split the top up time into 12 hours interval, each time for 5 minutes.

and voila, you have the cheapest DIYed "tubby"!
