Though this may be of intrest, there was talk about coral vs temp the other day somewhere

not really. the lighting stuff can be a bit Confusing. With fluro tubes wattage has little to no effect on "brightness" or you could say par. just thik of a 2ft tube compared to a 4ft tube. is the four foot tube brighter per Foot of tube There are different bulbs with different K (kelvin) rateings. depending on the K rating, this can give the impression of being brighter or dimmer.

you should just be able to lift the collection cup up a little.

did not know that was you selling them, you should of put them on the private trade and exchange. may have got more intrest

I founf the vodka did get rid of the cynao, but when i stopped dosing, it came back along with other types of algae.

yip. or if you want to have a bit more fun, poor a bit of meths down into the crack and light. SAFETY NOTE don't let children play with matches to offen

No need to tap the glass as this can cause (to the untrained) to run off. just scribe put a wooden pencil in the centre of the scribe. (on the underside of the panel) then push down with even pressure on both sides untill it breaks. you could also go down to your local glass shop and ask them to show you.

acrylic can warp at the cornors, if you do you use it use at least 6mm and ask the local plastic shop for the right one, whatever that is

is there a calcium build up

try BBC news, they had one a while ago

sweet, but what was the height

i am concerned about that calculator. Safty factor of 1.2? there is no way that would hold up. your water would be on the floor within a week. even 12 no good.

just push a little bit of glue out of the red tip, leave to dry. next time just pull it off and away you go. the glue won't etch into the glass, nothing will. you will find if you give the cloudy bit a good rub or get a new sharp razor blade it will come off.

yip you would be looking at 19mm glass. at 615 high you would be fine with 10mm or at 750 high you would be fine with 12mm

what sort of noise is it. a hmmmm or more nose from the pump?

were you using 400w se before, or have you just started using them with the new reflectors? Nice tidy job to.

Best person to speak to is kermit, not much this boy does not no flick him a pm

very interesting. By the way does anyone have the link to Sanjays page that has all diff types of bulbs listed and there par rating? i have the main page but can't seem to find the one with all the par ratings http://www.reeflightinginfo.arvixe.com/ This is also good for articles about ballasts, bulbs and reflectors. http://www.personal.psu.edu/faculty/s/b ... arium.html

i have a copy if you want to borrow it. red cover a

couple of 25mm bulkheads should be fine, as for sump heaps of designs around, they do not have to be that big either, for that size tank a sump around 900 x 450 x 450 would be sweet. What rate are you getting the glass for??
