the tank i have has a lid that houses the lighting, i could probably remove that without to much trouble, but there is a bar down the centre of the tank which i assume is supporting the tank.i dont think that it would be a good idea to cut out.what about adding some led's aswell as the t5,would that be an option.
i have had my aquamarine 900 for 15 months or so, the marisys 240 skims ok ish, no doubt there are better skimmers out there but its seems to be alot of work and faffing about fitting a better skimmer, so i just stuck with it.once i got it set up ijust keep on top of the maintenance, i clean the collection cup every week and wipe the plastic tube it fits into and i also change the air stones every 3 months.if you do find a skimmer which fits easily please let me know because the noise does my head in.
Recently i noticed two of my polyps were not at there best, on closer inspection i noticed a strange type of sluggy type thing amongst the polyps.After some investigating on the net i have come to the conclusion that it was a type of nudibranch.the info i have found is confusing some say get rid were as others seem to keep them, due to the state of my polyps i decided to give them an RO dip what came out of the polyps was around 10 to 15 of these creatures of various sizes on each polyp.i am now wondering what to do for the best, are these things a major issue?, should i treat my other corals? as they do not seem to be effected at the momment or if not treated will they multiply and overwhelm my tank?, can anyone give me some advise.Also i seem to have 4 or 5 tiny brittle stars which must of come in my liverock, i know that some are sand sifters and that some eat corals, how can i tell which type they are?
I have noticed that one of my clown fish has four black spots on it,I noticed two at first and over a few days more appeared,i dont have an anamone unless there s a tiny one which came on my live rock so i dont think they are stings,are there any parasitic or desease issues that cause small black spots about the size of suger grain or a little bigger .any ideas!
