This is probably going to sound crazy to a lot of people, but I have a 210 that has a sump installed. It was previously used when I got it and was already set up with the sump. The part that may sound crazy is I do not like the sump and purchased the fluval fx6 to try. In as best terms as I can understand lol how easily can I seal off the holes on bottom for hoses and how Do I remove safely the two black overflow (I think the term) from the back on the inside or is the removal of these not recommended?
 
you just want to install plugs in all the bulkheads. theyre available at most hardware stores. ive seen setups where some people run their canisters through the bulkheads. idk if you want to do that but it would just require a few plumbing components.

as for the overflow itself or weir, i dont think its advisable to remove them. ive only used them on acrylic tanks so idk about glass tanks though.

Yep, that does sound crazy. Lol

Unless you plan on keeping a pretty light stock, you will need more than one FX6. If you want to stock it heavily, I strongly recommend you get three of them.

Or, you could just do a little research and stick with the sump, or a combo of the sump and the FX6. The sump is more work to setup, but it is FAR easier to take care of. I have a 55 gallon sump for my 220 and it works fantastic. I wouldn’t even think of going with canisters or HOB’sover my sump. I can change the mechanical floss in just a few minutes, and the longest part of that is cutting the new piece off of the roll. Then, the course sponges can be rinsed in less than ten minutes. Remember this when you are spending two hours cleaning out your canisters. Lol.

In all seriousness, the FX6 is a good filter and will do well with a lightly stocked tank. I would recommend you leave the weirs where they are, and if you’re not going to use the bulkheads to attach to your canister(s), then just plug them up with some PVC plugs. However, if you don’t mind the plumbing, I would recommend using at least one of the bulkheads to plumb to the intake of the FX6. You can use both sides if you get another FX6.

Good luck and let us know how it goes!

you will have to plug the holes with capped bulkheads...i had the same issue as yourself..i got a used 150g that was drilled...i ended up using cut pcs of glass and i silliconed them over the holes bc i could not get new bulkheads to not leak (long story lol)...i kept the corner overflows bc i wanted to hide my dual fx6 intake pipes and heaters..i think the tank looks a lot cleaner wo seeing the heaters or intake pipes...

Not to mention you still get the surface skimming from the overflow box.

That's a great idea to use the overflows to hide everything. If I remove the hose from one of the bulkhead, is water going to come out? I'm trying to avoid moving my fish as they haven't been moved since in there and my arowana is big.

I apologize for the late reply but I'm doing it in the next week. I've got an arowana, Vieja synspilum, green terror and two bales. Is this considered heavily stocked? I'm ocd and do water changes every Monday.

I heard you have to alter a few things to connect to the canister. I'm not very smart when it comes to that part.
 
If you get threaded bulk head plugs, make sure you get the proper threading. Standard PVC fitting threads do not always work with bulk heads. And even when properly fit, use plenty of teflon tape on the threads.
A sump may seem daunting at first, but once you understand and get used to it, it is so much easier to wok with than things like canisters. And as someone said above, being able to hide unsightly equipment below is satisfying visually.
If the fish on your list are fairly young, it is not overstocked, but as adults they may easily max out that tank.
