http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=hello-wendikins-has-just-joined-#1 My husband and I are fairly new to fish keeping and have had a 180 ltr tank for about four months now and we are doing well. we have just aquired three bristlenose catfish to help with the cleaning !!! we made he mistake of leaving the light on all day, even while we were at work and this we have just discovered is why we were having to clean the glass so frequently. Now we have the light on when we are home form work in the evenings, we were told a maximum of 8 hours a day. This advice is something I have not seen in any of the books or websites I have looked at. wendikins 2008-07-06 http://forum.aqua-fish.net/?topic=hello-wendikins-has-just-joined-#2 Welcome .
