Lepperfish Posted February 10, 2005 Share Posted February 10, 2005 Hey guys, im just about to setup a new fry/growout tank and have a couple of questions. Should I use substrate from the parent tank or no substrate at all ? Also a few rocks and ornaments beneficial ? Tank is going to be a 2 footer. MikeW showed me a sera filter he has been using on his fry tanks as well. Anyone using these ? I was initially going to use 2 corner filters? There is about 35 fry id say as well - Mbuna. Cheers guys Link to comment Share on other sites More sharing options...
TropheusQueen Posted February 10, 2005 Share Posted February 10, 2005 Hey hey, Easier all round for fry tanks, regardless of size to, have no substrate. Most fry require, and benefit from, frequent water changes of 25 -50% at least a couple of times a week. There are some that will do daily changes No substrate makes this alot easier. It also enables the waste (uneaten food etc) to be seen and scooped up easily with a fine net. Any, air operated filter will do the trick. Sponge filters (your picture) are great and the fry can feed off them as well. We tend to use home made ice cream containers filled with appropriate gravel, coral sand etc to assist in adjusting pH and are air powered. Fry require frequent small feeds, a clean environment (hence the water changes and muck scooping) and not too much current -which makes air powered filtration ideal, as we want then to grow and put on weight not exercise and lose it. Pipes, ornaments, rocks etc depends on taste and whether the species requires hidey holes at that size . Hope this helps. Cheers Aline Link to comment Share on other sites More sharing options...
cosmiccreepers Posted February 10, 2005 Share Posted February 10, 2005 I use a filter that looks the same as yours, but is a different brand. Can't remember the name but I have 2 running in 2 tanks and have not had a problem. I have found though that the water must be twice the height of the sponges or the water will not be pumped through. So I sit the filter about 1/2 inch from the bottom. And yes, the fry do love picking little things from the sponges. Cheers, Cassandra. Link to comment Share on other sites More sharing options...
MikeWs Fish Posted February 11, 2005 Share Posted February 11, 2005 Hey Lepperfish, just saw this: AOA sponge filters Might be a better deal than the Sera ones. Link to comment Share on other sites More sharing options...
hungsta Posted February 11, 2005 Share Posted February 11, 2005 Hey guys, Would adding a sponge filter to the intake of HOB filter be suitable for a fry/growout tank? Link to comment Share on other sites More sharing options...

Ged Posted February 11, 2005 Share Posted February 11, 2005 What is the difference in cost between the Sera filters and the ones sold by AOA? Was there also a difference in the filtration ability of the Sera? Gerard Link to comment Share on other sites More sharing options...
