Some more Eclipse modifications for ya'll. I recently added a live plant to my Eclipse System 6. Since I wanted to begin adding fertilizers and carbon additive to the water I was going to need to stop having activated carbon in the filter lest it suck the ferts right out of the water as quick as I added them.
As you can see in my Eclipse review, http://www.fishforum.com/aquarium-pr...tem-6-a-19721/
, and in my filter mod, http://www.fishforum.com/diy-aquariu...iverter-20166/
, the filter is designed very specifically for use with a Marineland Rite-Size K cartridge in mind. Proper water distribution through the mechanical filter requires it lest a ton of water pass only through the first few inches of the cartridge and prematurely wear out the cartridge. So any modification was going to require the use of the cartridge.
My first mod was a disaster. Short story, I tried to cut the blue mechanical filter top off, dump out carbon, stuff it with bonded filter pad and then put a piece of bonded filter pad on top. It was a mess, we do not speak of it.
My second attempt came in from the bottom:
As you can see I used a box cutter to trim out some of the bottom grate and then dumped the carbon out. It's actually a surprisingly large amount. Probably sufficient to remain useful out to the cartridge's advertised life span. Go Marineland. At this point I could put the cartridge in and be done with it. It would be just as good a mechanical filter as it was before with just no carbon. I just can't leave well enough alone though.
As you can see here:
I cut up small strips of bonded filter pad and stuffed them into the cavities that used to hold carbon.
It's a relatively simple mod that anyone can do for their planted Eclipse tanks. In fact given the construction of all Marineland Rite-Size cartridges you can perform this mod on just about any Marineland filter to remove the carbon.
