no i don't, the tank just sits in the back room ignored for the most part. The only thing i do is pull clumps of hair algae I've just got crypts growing in there (the hair algae is from a "tree" i tried to do with fissidens and just can't get rid of it)
That moment when you go through your supplies closet and realize you have more substrate than you know what to do with. 30 liters of Amazonia, a bag of Azoo, bunches of UP Aqua, Akadama, tons of other inert substrates. That's the moment I'm in. Guess I'll need to set up a bunch of new tanks once my new fish room is ready.
This is when you think about setting up one biiiiiiiiiig tank! IIRC my 250gal is filled with four 5gal buckets of substrate.
I've got two 400ish gal tanks that will be set up at some point once I move. Would really, really love to be able to do Aquasoil in one of them (haha, fat chance, I can't sell BOTH kidneys) but will probably end up using cheap Safe T Sorb.
But I'm also converting two rooms (update: No I'm not! I'm just kidding! Maybe. Shhhh) into a single fish room for smaller tanks. Gonna let this serious case of Multiple Tank Syndrome flourish. Since I am being forced to move, it's my consolation and I am going to beat that horse dead dead dead. At least until there's no room left in the house.
On a related note: I need to remember to delete all of these comments if you-know-who ever decides to visit the forum. Heh.
