Oh. Sorry, that was me rushing. By top up water I meant for water changes. Having said that, I am glad you reminded me about salt not evaporating as I will need to top up if I have fan on and I would have used the pre mixed, salted water. Thanks for that. I have no corals in the tank, just a lot of live rock. Do lower pH levels not adversely affect the fish i have in there (Percola Clown and Royal Gramma).
Thanks. I will put heater back on. If I don't have the light on will the ph get too low. I am away for 2 weeks but have someone coming in to feed the fish each day. I have premixed the top up water so they can do a change whilst I am away. Using a fan sounds like a good idea. Will get onto that one. Thanks Gill PS - is this a normal problem or is it just my tank?
Well, progress of sorts. I have done a 20% water change this morning and now and the temp has fallen to 26 degrees. Not sure how much to attribute to water change (did not heat water again, it was room temp) and how much is lower air temp. Have no idea why temp went so high. However, the heater is still not turned on so I am a bit worried about turning it back on. Really bad timing as we go away in 2 days! If anyone has any ideas please let me know Thanks Gill
Hi. My Orca has been looking fab for a few months now and the inhabitants seem very content. I now have a Percola Clowm, Royal Gramma, 2 cleaner shrimps, 2 hermit crabs and a tiny red starfish. However, since the warmer weather has arrived the temperature has gone up in the tank. I did not notice for a couple of days and then saw that it was 29-30 degrees! I initially suspected faulty heater/thermostat/thermometre. However all are ok. I did a water change and did not heat the water and have now turned off the heater completely and the temp has stayed at 29 degrees. So far the fish seem fine but i do not know what else to do. The tank is not in sunlight or in a room that gets direct sun. We aew going on holiday in a few days and i am worried about leaving a tank with family that may start to suffer. How big a problem is this and can i don anything else?
Oops. Yes I did mean nitrate levels at 20 not ammonia I use bought RO water and do roughly 15% change 2-3 times a week to try and get level down. Can I ask my LFS to check quality of RO water? Is that a likely possibility. I don't want to risk offending them. I will reduce amout I feed first Thanks
Hi. I have been doing a water change of about 15% 2-3 times a week to try and keep down the levels. I was worried about doing more. The level has come down as it was getting closer to 40 than 20. Yes, i use RO water and I think the salt is "Tropic Marine" (I throw the box away as I store it in a large plastic container). I feed the fish twice a day. Will reduce what I put in and see if it makes a difference. Thanks
Hi again. Not been on for a while. My Orca tank has settled down and I am really pleased with how it looks. Now have a Clown. Royal Gramma, 2 hermit crabs, 2 cleaner shrimps and a feather duster. All seems to be going well. My ammonia is zero, Ph between 7.8 and 8.4 depending on time of day and amonia about 20. Doesn't seem to amtter what I do i ca not get ammonia mch belw this. I do water changes 2-3 times a week and have the nitrate absorbing pebbles in the filter. Is my nitrate too high and is it likely i overfeed. The fish seem to eat everything almost immediately when fed and the shrimp go potty to get at the food.(frozen mix or a marine dry food with added garlic. Everything looks healthy enough but having had nitrate problems before i am just eager to keep on top of it. Thanks for any advice Gill
Hooray. Althoug i lost my mandarin and shrimp it seems that my duster has survived.. It clearly was not happy as had seen no signs of life for over a week bu yesterday saw feathers starting to appear again. Really chuffed as was sure I had lost him. Thinks I must have calcualted dodage and not allowed enough for space taken up by rock. Will know better if I have to do it again.
I had been told that Mandarins were very difficult to sustain foodwise (after we had had him for about 3 months). Gorgeous as he was I will definately not be getting a replacement. I wonder now whether i did overdose on the treatment then. I had reduced dose due to inverts in tank but maybe not enough. How long does it take to work its way out of the water and how long before I can add another shrimp?
