Hey everyone, I have an Fx5 filter filtering a 90g tank. The tank has 4 bichirs, and I have not done a water change in a week and a half (I was supposed to do it today, but it did not work out). Today I attempted to add a UV clarifier, which did not work out (wrong one). In the process of doing this, I must have cracked the tube. Where it connects to the barrel valve, where the rubber seal and plastic meet, it is cracked. I set up a battery powered air pump. I have school tomorrow, and realistically get out at 4pm. The crack happened about 5 hours ago. The filter was still on until 10:30, so 4.5 hours. It lost an estimated 5 gallons of water. So basically it will be 24 hours since when the crack happened, or 19 hours since the filter was turned off until I can get it fixed. Will the fish survive?
 
When I used an fx6 I ditched the standard hoses pretty quickly in favor of 1" vinyl hose. You have to do some additional rigging with barb adapters and maybe even a DIY spray bar but it worked well for me.

I would get an airstone and air pump and just run that or if you have a sponge filter use that until you fix the can. Always a good idea to have an air powered setup in storage, ready to go if you need it in emergency.
 
Take the bio media from the filter and submerge it in the tank (preferably near where the airstone is located, this should keep the beneficial alive until the problem is fixed.
Can you post a pic of the area that's damaged? Some people may know how (if its possible) to repare it.
This is not the break, but it is cracked right along the seam and the rubber, circled in blue.
What happened to your in tank algae filter?
It is for smaller tanks. It wouldn’t suffice for the 90.

I do have a backup, but I learned that the one I bought doesn’t have the same size tubing as all the others, so I couldn’t set it up. I already have a DIY spray bar, but that looks too complicated. As long as they have a functioning hose, I’d rather do that. Why did you ditch the original hoses?

You will need to replace that hose if it is cracked in that spot, it is not fixable.

So now would be the time to switch to 1 inch vinyl hose as Backfromthedead Backfromthedead suggested in post #5. Maybe he can post some pics of his setup and give you some hints on hooking up that Clarifier you bought.

Ok. I still want to know why he switched.
