Diver Posted August 25, 2004 Report Share Posted August 25, 2004 I have a couple questions about my new native marine tank that I have had running for two weeks. I’m worried that the filter wool that I have in the top of the bio tower is filtering lots of the food before the animals get a chance to eat it. Also I found a lot of small shrimp in there that must have come from the NSW or rock I used. I’m also worried that if I remove it food will get caught in the coral rubble that I have in the bio tower and cause nitrate problems. What is the normal set-up, with or without filter wool? Second, is it possible to get a tank drilled for more holes without completely emptying it? thanks Diver Quote Link to comment Share on other sites More sharing options...
Brianemone Posted August 26, 2004 Report Share Posted August 26, 2004 filterwool needs to be changed regularly (it should only be for mechanical filtration) as for drilling holes in a setup tank :lol: :lol: :lol: :lol: its hard enough to get them drilled when they are empty (at least from what i've been through) the glass powder would go into the tank and they need to use water when they drillso that would make a bit of a mess on your carpet Quote Link to comment Share on other sites More sharing options...
chimera Posted August 26, 2004 Report Share Posted August 26, 2004 i think most remove filter wool, i did. doesnt achieve too much in the long term. dont even think about drilling a tank unless its completely emptied! Quote Link to comment Share on other sites More sharing options...
neopole Posted August 26, 2004 Report Share Posted August 26, 2004 my beach tank has been running a couple months now, and have removed the sponges from my filters, because it was stealing the food from my filterfeeders.ie mussles, pipis everything in the tank seems to growing better. my tank has dozens of snails and lots of crabs as well, so as to "turn over" the sand floor. all what my tank needs now is some fish, to give it some action. amazing how hard it is to get small fish!

jetskisteve Posted August 26, 2004 Report Share Posted August 26, 2004 try a good old fashioned baitcatcher & some patience Quote Link to comment Share on other sites More sharing options...
neopole Posted August 26, 2004 Report Share Posted August 26, 2004 ahhhh but where? the places i used to go to get little fish seem to be bare. or are not allowed. ie at the marina's between the boats. and the couple of wharfs in the manukau where the kids all used to go seem rather bare. also the estury next to the manukau golf coarse, seems bare. so if you know of any places i can go, would be very apreciated.

Ira Posted August 26, 2004 Report Share Posted August 26, 2004 Don't worry about the food getting caught in the rock. If you've got a couple shrimp in there they'll dig it all out anyway. Quote Link to comment Share on other sites More sharing options...
Diver Posted August 26, 2004 Author Report Share Posted August 26, 2004 That is what I had thought about the glass drilling. I wished I got the tank drill before filling it now I guess I will have to live with a pipe coming in from the top. Another question I have is the coral sand in the bottom of my tank is all moving to the back, I don’t think I have excesses amounts of water moment (not compared to some reef tanks) about 2500 lt/hour from the over flow and two 1000 lt/hour power heads which have outlets that move. Tank is about 550lt with sump. Should I just try moving the power heads to stop the sand moving or am I doomed to having deep sand at the back of the tank.

Brianemone Posted August 26, 2004 Report Share Posted August 26, 2004 holy carp sounds good to me the sand will move untill it finds its happy place Quote Link to comment Share on other sites More sharing options...
Ira Posted August 27, 2004 Report Share Posted August 27, 2004 Try adjusting the powerheads so that the flow is a bit more turbulent instead of a constant stream. It may still push the sand around, but if it tends to be more random it'll stay in place better. Quote Link to comment Share on other sites More sharing options...
