Here comes another addiction... going to reef! Mainly filtr. - 4/7/07 Thank you guys so much for putting real and honest info on the web for all to use free.... You have no doubt saved countless marine lives... After making it a point to read info on your site ever day when I get home from work for a couple hours, you might get some mail from the woman that's not so pleasant.. j/k) <Heeee! Say it isn't so!> Anyway after all the info from you guys I am going to ditch my wet/dry system and build a custom 55 Gallon sump. Finally here comes the question... I have a 180 gallon aquarium, 15 fish, some inverts and a button polyp, all medium size, finally ready to get bit by the coral bug. 225 pds LR, 220 pds Fiji pink sand, 2 Mag drive 12 pumps, one going to a large lifeguard chemical module with a little reef carbon, and one going to a large lifeguard mechanical module, <Mmm... not such a fan of this sort of filtration for this application... Do plan on switching out the cartridge every week (have at least two... with the one being cleaned in-between...> 2 Coralife 220 skimmers, and an 18 W UV, a hang on refuge (which will be replaced in the new sump. <No room to squeeze in one of larger volume?> Should I just remove the modules and use the mag's for return only due to all the live rock and sand, as well as a future large refuge in the sump with Chaeto? <Yes... a better plan> I figure I would take them off and utilize the extra flow potential from the pumps.. Thanx again! <Ah yes... we're in agreement here. Bob Fenner> If it's not broken don't fix it; too much filtration on a reef tank? 4/6/07 Hi guy's, love the site, <Thank you.> have been reading it for a while and am wondering if I am using to much filtration... <Hard to do...generally speaking. but let's see what we have.> I have a 180 gallon reef tank about 12 fish, <Small? Big?> 5 inverts, and 1 star button polyp. Here is what I have on the tank.. 225 pds LR, Overflow to a large sump with about 100 bioballs. A mag drive 12 running to a lifeguard {large) mechanical module. A mag12 running to a lifeguard (large) chemical module, about 1/2 full of reef carbon. A Coralife 220 skimmer, ORP monitor going to a small ozone generator, 200 pounds of Fiji pink sand, a CPR large refugium with Chaeto lit 24/7. I feel as though I might be wasting a lot with having all this...Any suggestions? <I think the plastic bio-media is a unnecessary, but the refugium probably refutes most ill effects it creates. From the sounds of it you have a functional, stable captive environment. It it's not broken don't fix it. The carbon, unless you have a lot of encroaching cnidaria life is probably not necessary on a continual basis either...but won't hurt anything either.> My fish are great, water chem great, and water crystal clear....Thanx in advance <Welcome, Adam J.> Sump I have a 29 gallon tank. My question is can this be turned into a sump? If so can you please provide me with instructions on how to build one and the materials required. >> Hmm, I would assume (and what I would do) that you're not going to cut the tank in question. You can make it into a sump using a submersible pump (or a canister filter of large flow rate), an in-tank, or hang-on skimmer, and a constant volume device... see these arrangements...at www.cprusa.com for illustrations. Bob Fenner Building a sump Bob, How hard is it to build a sump? Can you
point me in a good direction (internet site) for instructions on how to
build one? <A sump is just a chemically inert, water-holding
container... you can use a tank, plastic basin, bucket... or cut and
solvent plastics together, have glass cut, cut it yourself and silicone
one together (like a fish tank)... most folks use thru-hull fittings...
necessitating drilling holes through whatever sort of material walls
they're using... relatively easy with all but glass... which should
be cut before assembly... or you can do without thru-hulls... just use
submersible pumps, or plumbing that is primed to take the water up and
over the side of the sump.... No internet instruction sites for this
sort of job as far as I know... maybe you and I can/should make one? If
this is a one-time job, I'd just buy a pre-made container...>
PS: Is a single MH 250 watt light sufficient for a 50 gallon reef tank?
(anemone's, corals, coralline algae, etc.....) <Yes, if the
animals can be carefully placed to use the intensity and spectral mix
of the light source> Bob Fenner Gracias, Mike New Reef Aquarium, Basement Filtration Dear Bob, Thanks to you, 4 books, and numerous resources on the Web my plans are near completion. (The Escobar book you suggested was most helpful in plumbing the basement system and designing a proper U/V flow control.) <Good to hear.> A 1 inch surface drain through a pre-filter feeds a TurboFlotor 1000 in its own small sump (so water level can be precisely controlled). Skimmer effluent and overflow of its sump goes to a 30 gal. heated and lighted sump. Another 30 gal. tank above the sump provides for mixing and warming new water and is fed from an R/O unit. This tank plus a valved bulkhead drain at the "down 25% level" of the aquarium allows for easy water exchange from the basement. I intend to monitor total system gallons by the level in the big sump and add fresh R/O water as needed. An Iwaki 70 RLT 1500 gph pump powers circulation from the big sump through a mechanical filter, optional use carbon filter, and a bypass valved 30 Watt U/V unit. A 1 inch line returns to a flexible surface discharge. Three Rio power heads provide additional circulation. Lighting will be four 48 inch VHO tubes in an Ice Cap unit. I have several decisions on which I beg your advice: I can use either a 25 inch deep tank or a 30 inch for more water and more viewing, do I have enough light for 30 inches? <Hmm, not really... less you want to mount much of your photosynthetic life up on your rock... and hard to work on... unless it's a "proportional" element... in other words, a huge system> Is there any way to drain off the filtered residue from the TurboFlotor unit or install a much larger cup? <yes... carefully tap and drain the collectant in a "milk jug"...> Do you have a preference on powered filters? I am considering a Triple Rainbow Lifegard, a Nu-Clear, or an Ocean Clear) <The last two are very similar, the LifeGard is a piece of junk...> Can you give me a source for bulkheads with pipe fittings rather than hose fittings? <Take a look through a recent issue of FAMA, Grainger Supply online...> Can you give me a source for drain strainers that will keep fish out? <Build your own... Out of acrylic, solvent... what I do.> Any other advice or suggestions will be most appreciated. Howard >> <Yikes, not a mind reader (at least today), seems like you may know more than I do anyway! Bob Fenner>
