Water quality/lighting/bioload in biocube 14

[sharuq1]

I don't know where to put this question, so mods move it at your discretion. I have a small saltwater tank with frags:zoos, xenia & frogspawn, 2 clownfish, 3 astrea, 4 hermits and some other tiny things that came in on the LR such as tube worms. Clownfish are eating NLS without refusal so far, I think the frogspawn looks ok.

It is quite new, so have been doing weekly water changes (5g/change on a biocube 14--Is that an appropriate amount of water to be changing for this bioload?) and I am very worried about water quality as I would like to keep these new additions alive and healthy. Using prime to condition water changes, cycle, and also using some brine shrimp and some coralife invertebrate gumbo once a week into the clean water at change time.

Just bought the pom xenia/frogspawn/zoos yesterday and the green zoo is most definitely looking a whole lot less green. The xenia I am worried about as well. On a side track note-is clenching and unclenching a normal thing for xenia to be doing at night?

I am unsure of whether this is a true loss of color on their part (bleaching) or whether they just don't look as colorful in my tank due to lighting differences. Keeping a close eye on them to see if they look any different on a day to day basis. I am unsure whether this is due to the upset of moving them which would make sense-or the more worrisome issue of water quality. Tests look alright so far though.

Locals--Does anyone know if the red deer water quality is good enough for these things to thrive? I have been using the tap water. Keep in mind I have a very tight budget and I cannot at this time buy an RO/DI unit at the moment. (will consider for the future)
----->If the water is not good enough can you recommend the best place to buy water from in Red Deer?


**Lighting----have been hearing differing advice from people. With the type of lighting in the biocube 14 how long should actinics and 10k be on per day. I followed the advice of a LFS and they said 14 hours for actinic and 6-8 for 10k. Suggestions for types of corals that do well in this tank would also be appreciated.

**Bioload---Been hearing varying advice as to how much for this tank. LFS said it was alright to have quite a few corals and 4 fish?? My other half really wants a royal gramma and a tiny goby of some sort. I would like to accomodate him. (What is a small goby that has a good chance of living in this tank?) LFS said as long as I change water enough this would be possible--recommended a 50% change per week. I must say I am tempted.
