Don't worry, I had to do a double-take when I saw this too

Is there plenty of oxygen going into the water? Lack of O2 can cause red streaks in fins and if he is going up to the surface to take in air that might explain the buoyancy issues.

Ah brilliant! I'll get one ordered along with a new bulb.

Thanks guys for solving that one!

Hi Cathie,

If you mean the bulb, it's an Interpet.

If you mean the lighting unit I haven't a clue and I am currently away from home through work but I can check at the weekend (the lighting unit was second hand with the tank when we bought it)

If the starter has gone does that mean I need a whole new lighting unit?

Yeah good point, I'll certainly be buying a new bulb anyway as like you said it needed doing anyway.

If that doesn't help I guess it could be a whole new lighting unit....

Hi everyone,

Recently my aquarium light has started flashing intermittently. I put it down to the fact that the bulb might have slipped out of the connections slightly but I checked and the bulb was fastened tightly in so I've ruled that out.

I turned the light off as I was worried that the flashing would be disturbing the fish and thought it would also give the bulb a chance to cool down.

The next morning I tried the light again, and it is still flashing on and off about every couple of seconds or so.

Is this a sign that the bulb is on the way out? Admittedly the bulb is very old, we got it with the tank almost 2 years ago so it could be anywhere from 3 years old upwards so I was planning to replace it anyway.

But would a dying bulb behave in this way or could it be a problem with the lighting unit itself? Just wondered if anyone else had this issue, I'm hoping I can pop down the LFS this weekend and buy a new bulb and the problem will be sorted.

Your thoughts would be much appreciated

Me too - great idea and long overdue

I don't keep marine fish myself but I was always under the impression that maintaining a marine tank and keeping the inhabitants alive can be a rather challenging project (expensive too) and various types of equipment are required such as a protein skimmer, UV filter, live rock etc which is why sumps are always used with marine tanks to hide all the equipment and provide the necessary filtration.

I am surprised that Biorb have launched a "marine tank range" if I'm honest.

Anyway, someone else might have a better idea of how to proceed with this - sorry I couldn't be of more help

Too much hassle to return them to a shop?!? Sounds like a diamond bloke....

To be honest if I were you I'd immediately take them off his hands, sure ok 110l isn't the ideal size of tank for them but it'll be like an ocean to them in comparison to where they've been living currently and it would get them through till the New Year at least.

Once the New Year comes around you could then donate them to a local, reputable fish place (who may even give you a credit note for your trouble if the fish are well) or, if you've become attached to them you could look at upgrading the tank for them.

Overall, anything has got to be better than those poor fish spending any more time with that guy....or in the sewer.

Good luck! Hope it works out!

A depressing sight for an already drab and dreary Monday
