I have a blue led light from hydor i think it is - the biorb ones? suction cups to the inside of the tank or hood. Different effects can be created depending if you have it above or below the water. As it is a spot light efect you can get some good shaft of moonlight effects and if you have a ripple on the water surface it creat a rippled effect on the substrate. Not sure how much they are ?15 i think, had mine a while now and got a discount from where i used to work.
Heres the story. Cleaned the filter on Monday or tuesday night. Thursday morning we spot a bit of water at the bottom of the tank just as im going out the door to work. Thought it was just a spill from the clean as there was no obvious leak. Dryed up the water, took the top off the filter, tightend all the fittings on the pipes and reseated it. Turned it on and noticed that there was an extremely slight dribble from one of the four drain holes. - dificult to explain if you dont know the filter - but assumed the top or seal ring wasnt fitting properly. As i had to get to work i quickly seeded the old internal I had and got that going, stood the external in a bucket and im certain I turned the external off. Stupidly i didnt think to shut the pipes off as this would have prevented the flood. Now this dribble certainly wasnt enough to drain the tank on its own especially as it was stood in a bucket, so between 8am and 5pm 60ltr of water drained from the tank via the filter. In the panic my partner pulled all the plugs out the socket and cant remeber if the external was plugged in or not. I have managed to get a new o ring and set the external back up this morning and all seems fine at the moment. My conclusion is that effectively i set up a syphon and left it going all day. If i left the external on i probably would not of had the same volumn of water leak as the majority would of been put back to the tank. Or I left the filter on (too many plugs in the cabinet) and it pumped the water out. Was wondering if there was anything i may have overlooked?
Plastic sheeting is a godsend, couple of quid for 2mx1m from the garden centre. Spread it out in front of the tank when doing any work so that if you do spill a little bit it can be mopped up easily. Doesnt matter how careful I am there is always some water that goes on the floor from removing plants, dismantling a filter etc, have even had a bucket skid along the top of the tank when topping up and dump a bit on the floor stick my arm into prune a plant or such like there is aways some water.
Doesnt help when your external malfunctions though
Can anyone suggest why my Fluval 205 external has pumped 3/4 of a tank cross the lounge floor? and more importantly how I prevent it doing so in the future. The mrs is not impressed at coming home to find a waterfeature in the middle of the floor and downstairs werent thrilled with their waterfall!
Ive got a pair of shrimps in my 2fter and they do a cracking job of keeping the algae at bay, ive had mine for about 6 months - sposed to live for about 2 years. Only thing you have to make sure is that none of your fish are big enough to eat them or they will get big enough to eat them.
Ive just used sellotape along the top edge and stuck it to the top edge of the glass and let it hang down behind the tank. No air bubbles easily removed to change or wipe down if water has got behind it.
