filtration

[shime24]

I have a 75 gallon tank, It is my first tank I have had it for about 4 months now. I have a fluval 405 canister system, should I add a 2nd one or is that over kill and a waste of money. or should I go a different route, like a sump?

Depends on the bioload good rule of thumb with filtration, more is usually better:)

the interweb is telling me that your filter is rated up to 100 gallons. from that, i would do some water tests to determine if it is holding it's own. if not, supplement! if there is any doubt, just remember you can never have too much filtration... although i don't necessarily think you need to add a sump at this point ;)

What are the benefits of using a sump?

I have a 405 on my 110 tall and it works great! Tank is fully stocked. No wiggle room! No issues at all.

All depends on your uniq conditions... I have a 75 and started with a fluval 405, but it never did quite filter out all the floating particles, close but just a little undersized. Added a C-360 and all is well.

If it keeps your water clean and cycled well then you are good. If not, upgrade or add another filter.

You could always add another filter if you feel you must and as everyone here has stated (it never hurts to over filtrate) in my opinion sumps are nightmare waiting to happen, don't get me wrong they have their benefits but in your case i don't see it.

You would be better off spending that money on another canister or jumping into the diatom filters using diatomaceous earth to polish the water but this is very expensive.

Another type of filtration that could work for you in conjunction with your canister would be those dual marineland hang on filters with the biowheels.

Good luck..

i have been looking around for a canister filter. i found some fluval 405s for 100 is that good for ebay?

I sggest another canister...provided the flow doesn't cause issue. Depending on your stock, the sump can help increase overall volume and allow an area for more fishies or inverts or plants.

Sumps are easy to care for and clean. If not done properly they can become a Nitrate factory. Since they increase your total water volume, it increases the amount of available water. If saltwater, a general rule of thumb is that a sump should be 1/3 tank size. For fresh it can be 1/5. It can also be less if used inn conjunction with another filter. It just depends on your particular needs.

A canister is a very good system and is simply a different method to clean the water. For water polishing, different media can be used to achieve it. "DE" is one of many methods. Using a more dense material is less expensive and does just as well as DE but can slow your water turnover slightly.

Your canister is adequate for most stocking and I would add another filter if I had messy fish such as goldfish, plecos, or Oscars, etc.

Yeah, I paid 200 for mine at pet smart
