Nano advice

I'm wanting to setup a 10 and two 5 gallons. I'm having a hard time determining lighting for both. I want low to med.... I don't want to mess with co2 at all, not even excel.

Also, instead of the 5 gallons, I could possible go with something else. Like a cube or a pico or something... I'm just having trouble locating the stuff online to look at for ideas.

I'm all about the Picotope, check out my sig for a link. It comes with a light that is good enough (barely) for low light plants. Get something very hardy, but you're gonna have to have some sort of fertilizer.

Yeah I saw the picotopes at the LFS for like $41.00 the other day. I like them, but I was leaning more towards a 5 gallon, so I could put the glass top on it, without having to get one made for a pico. I really don't like the size of the 5 though. I would rather have a cube, but I can't find them locally, at least no where that I have checked.

High light can be a major catlyst for algae as many newbies have found out the hard way, unless you match that with a good fert program like Estimative Index, good substrate(ADA Aquasoil) and consistent c02 levels, preferably through pressurized c02. This also applies to 5 gallons(been there done that).

FWIW, through experimentation I found that I obtained best results on my 5 gallons with 14 watt 6400-6500 K compact fluorescent bulbs, any higher than that even with a 8 hour photoperiod resulted in a number of green spot algae patches on the tank walls. This was for a low tech Tom Barr type setup, no c02 injection, but regular/daily dosing of Seachem Excel.

If you really want to monkey around with light and want to avoid potential algae issues, you can start with high intensity and keep the photoperiod really low, increasing it by say 30 minutes a week to see where it takes you.

Yeah, I use Tom's non co2, low light method now on my 29 and it's great. I want to achieve that on my smaller tanks, that I'm going to buy. I know the lighting is different on smaller tanks though, that's why I'm having trouble coming up with the right idea.

I hear you, they say that the watts per gallon rules break down for smaller tanks. I have read people having as much as 20 watts with fixuture positioned 2.5 inches over the top of 3 gallons without any problems.

It may just be a matter of trial and error on your part and proceeding with the utmost caution to see what happens. I would suggest Tom Barr's Dry Emersed Method to jump start plant growth, that way if you err on having too much light you may have some level of protection against algae from the high plant density and firmly established plant growth.

Good idea. Didn't even think about that.

You know, in all honesty. If I trusted that I could do it, here is what I would do. I would go by a 15 or 20 long. Get some glass cut and divide the tank into separate aquariums that way, but I don't trust myself trying to silicon everything right. lol I'm not much of a handyman.

I just thought about something. I guess I can't do it that way because of different temps, needed for different tanks.

Brad,
I have had a great experience with the CoraLife Mini AquaLight, which runs two 9w 6700k bulbs, and can be had from Big Al's for $25.

I run one over my 5.5g RCS colony, which is modestly planted with Java moss and hairgrass.

Seven-hour photoperiod + Flourite + no regular ferts = slow growth + a little dust algae.

The fixture's only shortcoming is that CoraLife doesn't make legs for it, but you can search around these forums and find DIY solutions.

Good luck,
Matt
