Figuring out tank chemistry can be very frustrating....We are just here to help you do this, and hopefully before any more fish die.
>> Thank you all for your help. My Gourami is still alive, so far, but still not eating which worries me. I am hoping he's just having a "spell" and will snap out of it any day now.
>> I have listed my answers below each question...
Lights don't seem to be a problem. The rule on lights and Algae is that if you keep lights on more than 10 hours a day, it will encourage algae growth. I feel the blue is just as likely to do this as the white....So if you could turn all lights off for 4 or 5 hours during the day when the fish are not feeding and maybe you can still see them it should help cut algae growth....The question of if your "plants" will be able to use the blue light is only viable if you have plants, and as far as I can see you haven't said you even have real plants....
>>No, we don't have any live plants - have heard that's a lot of work and basically a hobby in itself. We have 3-4 fake plants, a piece of driftwood and a small-medium piece of coral (from LFS, not from beach). We used to also have a larger rock that had holes in it (for the fish to hide/swim through) but we took it out last weekend because a) a fish had died in it (ew), b) the algae loved it, c) we wanted to give the fish more swim space.
>>We moved the tank last week so I don't have to have the lights on all day to see the fish, the ambient (not direct) sunlight is enough to see through the tank (well, when it was clear, anyway). So, I have only been putting the white light to feed. When things clear up (hopefully), I may turn on the blue lights for a couple of hours at night so we can enjoy the fish. If you all think the blue lights aren't good for the freshwater fish, I will just use the white.
Keeping a chart for your test results will help you track exactly what happens in your tank.
>> We do keep a log - we're currently using the one that came with the API master test kit but that's about to be full so I plan to make my own log and keep them in the notebook binder I started when we got the tank. I do write down dates and notes of all the things we do - unless my husband adds something and doesn't tell me (he's not as organized/anal as me).
You can test PH, but don't worry about it. When people first start with their tanks this seems to be something that is really worrisome, because everything you read on fish gives the optimal ph range they live at.....Usually this is not a problem with fish unless you get into breeding....Even Discus, one of the most picky about ph, will live and thrive under a variety of ph levels as long as the water is CLEAN, CLEAN, CLEAN.....No ammonia, nitrites, and low Nitrates.....So it boils down to this. Don't try to change the ph. and don't worry about it right now.
>> My husband has added stabilizer to adjust the PH -- again, because the LFS said it was a little high (I don't agree - as I said, from the research I did on our fish the PH wouldn't have been a problem). I will let him know not to add anymore.
In your last test you are not saying what
ammonia tested at.
>> Unfortunately my husband didn't write down the last two sets of tests because he said they were all good (I could kick him). The ammonia level tester chip that's in the tank shows it's at a safe level. Though, I wonder how often we have to replace those things - every month or every 3 months.
What water tests do you use? Most here recommend the API Master Test Kit, for freshwater. If you can do your own tests every day, and chart the results, until your tank is through the cycle it will help.
>> Yes, we have the API Master Test Kit for freshwater. Looks like the LFS made at least ONE good suggestion
Anything that happens between now and then, could include spikes of ammonia or nitrite which will kill fish, so you have to do partial water changes every day of approx. 25%, you can add Prime (a treatment to detoxify ammonia and nitrite), OR you can add bio-spira (a bacterial culture to help speed the growth of bacteria that will convert ammonia to nitrite, and nitrite to nitrate) DON'T worry any more about the cloudiness....it is as said before, a Bacterial Bloom.....You want this to happen and it will clear itself in a week or more.....Until the bacteria has a chance to grow you won't have a cycled tank.
>>He said he added Prime when we did the water change last weekend. Yesterday he added the liquid bacteria stuff (Cycle), so hopefully we're on our way back to being cycled. I will trust all of your combined experience and not worry about the cloudiness - if you say it doesn't hurt the fish then I'm okay. We were just worried it was "choking" them because it seemed like the equivalent to "bad air pollution" to us. Plus it just kept getting more and more cloudy - we waited a couple of weeks for it to get better and it never did. But I will make sure we wait it out this time. Obviously the full water changes didn't help and actually did harm so we won't be doing that again.
Weekly water changes of 25-50%, and gravel vacuuming 1/2 the tank every week is normal tank maintenance for most of us.
>> Do you also remove the plants and rocks to clean them? Or do you just have a pleco or otto do that job for you?
I rinse my filter material at the time I do water changes, in discarded tank water....I do not use carbon, unless I have medicated and then only for 24 hours to remove the medications after treatment. I DO NOT CHANGE FILTER MEDIA, unless it is in rags.
>> We have a 14 gallon Biocube...

...which has a specific filter (which does have charcoal in it) - not sure if they offer one without charcoal - I'll have to check into it. It also has another sponge in the Wet/dry section, plus the bio balls. Since this tank has specific parts we don't really have the option of making our own stuff.
