hi..the wood u use is for support while the silicone cures? or is there any other purpose...

wow..dat's one hell of an idea!! anybod done dat?hehehe

nuttin really bothering me..just wondering what will happen. Like i saw one of the members here have a sump tank at higher level than his main tank. water is pumped from main tank up to sump then from sump overflow back down to main tank. considering whether to put sump above or below tank due to space, size and arrangement concerns.

hi all, i know one of the advantages of have a sump below the tank is that the water level in the main tank will stay constant, evaporation will only deplete the water level in the sump. But wad if the sump is overhead the main tank? the opposite is true isit? the water level in sump will be constant and level in tank drop?

hehe ok..thanks alot of all your advices.

oh i see what you mean..hmm yeah u've got a point..thanks.. any ideas on how can i adjust my tank water level next time if i install a overflow chamber?

oh?i thought usually everybod encourage drilling of holes for overflow instead of using those hang on back siphon? hmm..this is because siphons have a chance to fail...unless the tank is already bought without a hole, then i guess u cant help it...guess i've been reading something different, what are the opinions of any other experts? btw, i posted a tread called closedloop siphon which is a real simple siphon overflow made of pvc pipes. might be of some interest.

ah i see..the noise can be solved easily then..well..i want a overflow to drain water to sump tank below..simple as dat... thanx for the advice

hi guys, saw this design on these websites using a loopback siphon to bring water from the main tank down to the sump. Simple design made using PVC pipes only. Thought might be a gd and cheap solution to overflows. http://www.petprovision.com/Articles/Doubl...DeckFilter.html http://www.thekrib.com/Filters/overflow-skimmer.html#7 (look under the design by David W. Webb)

yeah this is wad i'm asking, having a straight PVC pipe connected to a bottom bulkhead...will it be noisy? as for fish getting sucked in, i can always put some netting or eggcrates over the top of the pvc pipe. the main issue is just the possible noise.

ok now i understand Durso. actually i do not want an overflow chamber in the tank as i want to leave the option of changing my water level later. If by using juz a pvc pipe installed into the bottom bulkhead, i can adjust the water level by changing the length of the pvc pipe. i'm still planning b4 telling the custom tank maker what i want exactly. i'm not drilling it myself of cos. thanx for the links..i dun trust the hang on back overflow boxes after reading much horror stories

oh..hmm..so i misunderstood the use of Durso standpipes? Are these only for use in overflow chambers? so if i dun intend to use overflow chambers, there is no need for me to use the Durso to reduce noise of water flowing down my drain to the sump? If i just put a pvc pipe to the bulkhead at the bottom, will it be very noisy? 1st time using sump, so alot of questions..hope u guys dun mind as for drilling the back, i thought if next time i change the stand to a cabinet, there is no need for me to drill the cabinet for the drain to go through. other than this reason, is there any diff betw drilling the back or bottom? for eg, will a drilled bottom suffer more in terms of integrity of the glass?

Hi, am considering whether to drill the back or bottom of the tank. Can i use the Durso standpipe if i drill the back of the tank? A PVC elbow can be attached to the hole at the back and then the Durso standpipe is attached to the elbow. Will this work? Anyway, wad are the advantages of drilling the back or bottom?
