qx....My friend dont give up on this hobby. I see your point and i see all of every one elses point. There right when they say there just trying to help you, and thats cool. Your tank is still cycling? Then let it cycle, most of the diatoms will go away when it has cycled and balances out. I do see your point on trying to find a cheeper way to do things with your tank, Im always trying new things my self some work and some dont. Just remember all thoses poeple that was laught at and made fun of when they came up with a idea and sure they falled many times befor they succeded, who cares your learning, be a thinker figure out what works for you, but dont give up, but don't also be a fool and not take advice. Blend the two together, dont we all try to do this in every day life? We all dont know all the answers at first but we learn from are mistakes of what could work and what dont. I think if you dont have the space for a sump, then what you came up with is a good idea at a cheap price, its a lot cheeper than some one going out to buy a new canister filter. When i got my tank it had a fluval 405 canaster filter and had two clean it once a week or every two weeks eventualy it took a shit on me and i whent to a wet/dry filter i havent had to many problems with it but i still wounder really how good is it, my nitrats are still good but that could all change. The filter you bought i think is a good idea, It filters the water we drink why not filter out the water your fish are living in? but as we all know we still have to keep a check on what are fish are living in because they sure cant check it, they'll just check out if things are not going good for them. All the people at the fish store at first are all full of shit to a point lets face it there in buisiness trying to make money they dont really know you, they get there 300% mark up or some thing like that, getting your own bisiness liscience may be a cheaper way to go? Thats what i may try to do in the future?....but once you get to know them they'll tell you a diffrent story on how they keep there tanks but you have to realize that there tanks or most of there tanks are always changing. Ours pretty much stay the same,same fish, same rock, same sand. Just dont piss off the fish stores because they do have there perks when you make good friends with them. I go to every one in my town and Im friends with them all, and they all now give me good advance, I just keep most of my defirences to my self for the most part when Im trying some thing new out. Some poeple are thinkers and some are not but be cool to the people that are trying to help you out. Thats what this forums all about for the most part. We all need to be a little more understanding this hobby dont have to be this expensive. Some one else sure had the idea of having the ocean in are living rooms. Im just trying to keep the peice. Its all good LOL
