I've recently bought a 55g tank from one of my professors that came with an undergravel filter. Knowing this wouldnt provided enough filtration (or current) for my desired fish, i bought a HOT magnum 250. This thing worked great for the first month or so, but recently it's been crapping out.
I had added some peat to the filter in hopes to lower my pH. After a few days i noticed there was very little current in the water. I checked out the filter, and the peat was causing the blockage. So i cleaned out the canister, rinsed the filter really well, and reassmbled it. Now, the filter barely trickles any water with the filter element in. I removed it and put in the waterpolishing thingy just so my fish could have some current back.
I have two questions about this.
1- i've decieded i want to construct a small wet/dry in the sump i've created. what's an economical way to approach this. my sump is a 10g. i would also like to have a refuge down there, but i think space may be an issue.
2- was the peat the real reason for this filter media clogging up so quickly? I've heard that these magnum canisters really do well at mechanical filtration and get really dirty really quick. If this is true, i dont think i can afford to replace a 15.00 filter element every month. Or i'd like to not have to.
