the 220 gallon i looked at, just refound the craigslist post...and it was originally priced at 550...i talked him down to 200 lol...so i guess its a bit overpriced as well
id get some sponge filters to aid in the bio load. Also if fx5 still interest you. you can add a 4 inch foam to the inside of the media baskets which i think it comes with 2 inch did not measure. this would increase the amount of contact time with the bacteria. Also buying 1 inch diameter vinyl clear hose either the one without the braided or with braided has less kinks. And adding a piece of pvc 90 degree onto the end of the output will increase the flow from the previous crinkle hosing that comes with it. I just did the hose transfer on mine took about 10 minutes and costed roughly 25 bucks. I plan to get poret foam 4" for the media basket at either 20ppi or 30 ppi but undecided atm.
I just picked up my $29, 29 gallon sump from PetCo yesterday. Pretty hard to beat the price. My current sump is a commercially manufactured trickle filter about 10 gallons in size. There just isn't that much to building a trickle filter although many seem to want to make it much harder and more complex than it should be. I am going to model my DIY sump after my commercial sump. One big chamber for bio balls and a second much smaller one to allow me to get the pump in and out without removing all the bio balls. On top of the bioballs is a drip plate with a filter mat in it which is very easy to get to for cleaning. My 10 gallon does a great job cleaning the water and breaking down the ammonia. But it's real strength is being better than any other filter I have ever used at oxygenating the water!
IMHO a nice complement to a sump is a Magnum 350 filter for water polishing.
ok so 3 months or so later, i have the 220 gallon, i filled it...it leaked...I have resealed it completely and the water test is coming soon to see if it can hold the weight of the water ..*fingers crossed*.. but i think i did a good job...
looking for a forum on how to make a trickle down filter, or my own sump...what size sump tank would i need for a 200+ tank...
i think this is the correct forum search around here for diy wet/dry filters.
as far as size for the sump, i believe the bigger the better is the correct answer. the main thing you have to make sure of is that the sump is big enough not to overflow if the power goes off and the pump stops working. This is going to depend on where the drain and return is located on your tank and how much surface water will drain out when the pump turns off.
