i thought i'll so something different for my 1000's post. WOW i post a lot!!! average 4 post a day. hope i dont talk too much Cr@p :oops:
rivertank= tank with a continuous one directional flow of water.
i am goin to do a very simple walk though on the steps i took in building this river tank. its an 2.5' X 1' X 1' tank. this particular tank is build for Plecos. [5 X L226]
equipment needed: tank, clear tube, double sponge filter, pump/powerhead, saw or scissors, substrate of ur choice and 1 X L joint.
this is done on the cheap but u can do this on a much larger scale and replace clear tubing with PVC pipes. u could also make ur own sponge filter intake by drilling multiple holes into the pipe or have multiple sponge filter with a larger powerhead.........skys the limit.
first i have to straighten the clear piping and i did this by sticking a piece of bamboo though it then pour boiling water over it quickly followed by cold water this setting the pipe straight.
i used a fluval double sponge filter and just replaced the original piping with the clear tube shown below.
now cut the tubing to the length of the tank, leaving enough room to accommodate the size of ur powerhead. connect the L joint to the other end and add an piece of tubing to the height u want ur powerhead to be.
i started the tank with sand base just because i had some lying around so its really not needed.
its that easy now u have the intake on one side and powerhead on the other.
i then over the piping with peat as these particular plecos comes from the back waters of peru where the water is very soft and most properly tanned.
i then sprayed the peat wet so it doesn't float when i fill the tank up. instead of peat u could use all sand or just straight to gravel. for a planted tank use proper planting mix.
final layer i used fine gravel. if ur goin to use peat u would have to have another layer on top to avoid a mess with floating bit of peat.
now u can fill the tank up and attach the powerhead and heater if needed. i used a cheap 800L/h Nova pump. added some plants and fish to help cycle the tank.
best to use a powerhead with adjustable flow because u might find the ur flow is too strong and the current is hitting the other side and bouncing back rather than though the intake. to test if ur river tank is successful put a piece of cork or something similar and see if it floats to the end and stays there if it does then SUCCESS!! if it hits the end and bounce back then current is too strong or not enough intake, if the cork don't make it to the end the u need a stronger powerhead.
i then added more half pots as caves as i dont have enough drift/bog wood. this pic is 1 week later
then 2 weeks later.
the tanks has been set up for a few months now and the system works great. wouldn't change anything to it but would strongly suggest to use PVC piping if u can just to make the overall system stronger as i am finding the soft tubing easily be pulled up if ur not careful while taking the sponge out for cleaning.
i have most properly missed something or are unclear at explaining certain areas so all question and comments are welcome
