i noticed some posts where members have cautioned others about using rock that can leach metal. is there any way to test for metal? just curious.

i would like to use my table saw to cut acrylic. i have a 200 tooth blade. would that work to make good clean cuts?

my LR is on the way. i will be adding to a new tank so i will cure in the tank. i could use advice with what i should do to prepare. water chemistry, temperature, cleaning the rocks, water flow, aquascaping, etc...

what are the pros and cons for closed loop vs sump?

as i read through various forums i am noticing that more than a few people are running sumpless systems and just use filtration provided by LS and LR. so i just wanted to take a poll to see how many of you folks are running your systems without a sump.

in my endless research i have come across the term "closed loop". can someone explain what a closed loop system is and what are the advantages and disadvantages.

i was just wondering how often you folks are changing your filters on the RO/DI unit?

what type of adhesive should be used to glue acrylic baffles to a glass sump (aquarium used as a sump)?

has any of you folks ever placed a HOB filter on your sump to occasionally use for running carbon or polishing the water. just curious?

i would like to add another overflow to my tank or, perhaps, upgrade my overflow. when i go to my favorite online stores, i only see CPR overflows. after reading posts about the CPR units on this site, i have decided to steer clear of them. so what kind of overflows do you flolks use and what...

has anyone ever used a flow meter to get an accurate reading of the return output? if so, what flow meter did you use and where did you get it?

i have a 48" 4x65watt satallite PC lighting system. the fan noise is very annoying. i surrender. i was going to change out the fan, however, to get a fan with same CFM still creates a lot noise. i need to get another lighting system. so, i would like to get something similar with a...

i came across this sump/fuge combo. does anyone have any experience with this or know someone that does? looks interesting. i guess my only concern would be the quality of the skimmer. any opinions?

i just made a stockman standpipe (real easy and real cheap). however, i notice that, while the noise was a bit less, my overflow was still making a bunch of noise. the slurping and gurgling stopped, however, i was getting noise from the waterfall effect as the water spills from the primary...

are inverts supposed to be quarantined?

i have an external return pump for my sump, however, i have a mag 7 internal pump in my sump that runs my ev-180 skimmer. it is causing my water temp to rise to 84 degrees. if i turn off the skimmer pump, my water temp drops to 80 or 81. my question... would it be detrimental to just run...

my overflow is really noisy (waterfall, slurping and gurgling). as i did some research, i see that a lot of you folks use a durso standpipe. ok, so i have a couple questions... first... the overflow box hanging on the outside of my aquarium has two chambers. one chamber is for the output of...

i put sand in my tank and as expected i got a sand storm. as others on this board have suggested, i am just going to wait it out till the sand settles. i am not in a hurry. it has been 4 days and the tank is just starting to clear up. i can see about 2 to 3 inches into the tank. i noticed...

i recently bought a light hood with a fan. the manufacturer states that a canopy should not be used with this light hood. well, it was obvious that the reason was that the fan could not vent because the intake and outlet would be blocked by the canopy. because i am new to this hobby, i didn't...

i am setting up my 75gal tank. i have a sump (actually its a wet/dry without the bio-balls) that houses my ev-180 skimmer and a heater. i placed sand in my tank and, as expected, i got a sand storm. a buddy of mine gave me a fluval 404 cannister filter some time ago. so i decided to hook it...

i just got a new lighting system (satellite w/4ea 65watt PC and 2 moonlights). there is a fan in the unit that is pretty loud. is this fan required? can i opt to run the lighting system without the fan?

i just filled my tank and i have 3 maxi-jet 1200's running. i was curious as how most of you have adjusted the air control valve. right now i have adjusted it so that it just barely starts pump fine bubbles. it this correct?

i have an aquac ev-180 skimmer running in my sump. the water coming out of the return gate valve pours the water back into the sump, making a loud splashing noise. do i need to raise the water level in the sump higher to reduce the noisy waterfall effect? if so, will the skimmer work...

it seems like we have general formula's based mostly on "per gallon". for instance, 1 fish per 5 gals, 5% to 10% water change per week, 1 cleaner crew member per gal, etc. anyway, you get the idea. i am sure this is obvious to you folks, but it seems that much of the water volume is displaced...

i just finished plumbing my sump. to break siphon in the event of a power failure, most of the people on this site have recommended drilling a hole just below the waterline on the return tube. what size hole are most of you drilling. also, i understand that the hole will break siphon on a...
