Put some rock rubble into the bottom of a small plastic container with some holes in the sides. Pop your shroom in then keep your hand over the top while you get the container into a low flow area. Leave it alone for a few days and it should attach to a bit of rubble, then you can milliput it to wherever you want it.
An inch or less sand is fine for the Berlin method of filtration where the live rock is the basis of filtration. If you go much higher it is classed as deep sand bed filtration which is different altogether. I don't know very much about this method but I don't think you are supposed to disturb the sand bed once its in place i.e no burrowing fish/snails. The deeper the sand bed is the more chances of getting trapped hydrogen sulfide, which when released into the tank can be very harmful to inhabitants.
Cleaning tank - if it's been used before it could have coraline algae deposits on glass and back panel. Tip the tank over on its side and soak the areas with normal household white vinegar, leave it on for a while and it should scrape away easily. Give it a good rinse afterwards with some plain warm tap water and let it dry. If you want you can soak the tank in Miltons fluid (the stuff for sterilizing baby's bottles)then give it a good rinse afterwards.
My orca is the 58 litre one, not sure what yours holds(is it 128?) when I first set mine up I added 20lb live sand(made it about an inch deep) and 6kg of live rock. I wasn't happy with the initial 6kg it looked a bit sparse, I'll leave a link to it before I added another 4-5kg.
I usually use Coral Culture and STM for marine specific items. For powerheads try Aquacadabra on fleabay, they are very good normally. Don't waste your money on a hydrometer, they are rubbish, get a decent refractometer instead
Hi crackerjack, firstly sorry to hear you are having problems at the moment. Could you just confirm your test results as regards to Nitrite?, did you get it mixed up with Nitrate in your earlier post?, which test kits are you using ?. If you are getting a reading of more than zero then your tank isn't cycled properly. Looking back through your history you don't mention anything about fishlessly cycling your tank. You have stocked the tank too quickly, ie 4 fish and corals in the three weeks since first setting up the tank. If the tank wasn't cycled properly all of your fish are at risk, even if they have managed to avoid whitespot from Dory. Please let us know how things are going so we can help.
Hi electrogear, when you got the 3 Chromis did the LFS bag them up seperately or all in the same bag. I ask this because they are notorious for picking each other off until just the strongest remains. They look like butter wouldn't melt with the lights on but come darkness another story altogether. They could have picked on the weakest in the 50minute journey, explaining the first death. Not sure what to say about the B/Cardinals but I don't think I would be using the same LFS again if the fish were on their last legs after a relatively short journey.
Hi nith, it all depends on what you want to keep in a marine setup. If you have ever dosed any copper based medications to these tanks you won't be able to keep invertibrates as some traces will always remain. This will leach out of the silicon joints and kill these sensitive creatures. For fish only or fish only with live rock (FOWLR) it will be fine if meds have been used. Whatever you decide, take your time and do lots of research first, and ask lots of questions even if they seem silly.
