    L- a 24 w T5 or a 20w T12 would be best.
    A 24w T5 should be raised as suggested (6") in prior posting.

    GH and KH will drop over time if you do not do water changes and prune and export plant biomass. So just use tap.
    Top off with tap also.

      Are my plant choices limited when using this kind of set up or are there specific types I should avoid and lean towards?

      I was thinking of having a schooling group of fish and like that 'look'. I was leaning towards neon tetras but if someone suggests something else I would consider.

      I think I read about an algae eater but I could not find the specific name?

      I know, lots of questions, but beginners always are. Aren't they?

      Thanks so much and hope this thread is not too old to get a response.

      I think I mentioned several types previously in the article.
      Generally easier bread and butter type plants are best, money wort, Java fern, water sprite, Egeria, Hygro's and the like.
      Then you phase in harder to grow plants slowly.

      Amano shrimp are suitable for smaller schooling fish.
      Very good cleaners, SAE's also.

        My non-CO2 experiences

        I've been running an EI-method 72g for some time. I've had a lot of success with a wide variety of plants,

        but now that I have a decent size fish load, dealing with algae issues has been a bit of a challenge.

        On the other hand, I have a few smaller tanks with no EI or CO2 (and no ferts beyond fish food and wastes, and with easier, low light plants (egeria, anubias, ...) I've had a lot of luck as well.

        I do weekly 50% water changes on all tanks, but other than that the non-CO2 have been low light, low work as Tom has suggested, but perhaps a little less interesting in some ways.

          I am interested in setting up a non co2 tank. I have a pressurized co2 tank and am getting ready to set up an excel tank and eventually a non co2 tank. It's winter in New England so what else am I going to do ? I would like to compare different methods. I have some questions on your article.

          1. Can I use Eco complete for a substrate ? If it can be used do I still need mulm and a carbon source such as leonardite ? If I need it ,where can I get leonardite ?

          2. Are any water changes ever needed ? If so, how much, when, what is the best way to do it ?

          3. I was thinking about using a powerhead and sponge or power filter and floss for circulation. What do you suggest ? Is outgassing an issue ? I realize this is a non co2 tank but there will be small amounts of co2 present . Does this need to be preserved ?

            Yes, EC will work great.
            Leonardite may be added, mulm should be no matter what type of tank. Hydroponics stores sell it, Diamond Black or something or another.

            WC are not needed unless you doa major rework/uprooting etc, once every 6months perhaps.

            I'd personally use a canister filter or a HOB filter.
            Never been a fan of internal filters, that's tank space better suited for other items(fish, plants etc).

              Thanks Tom,

              How's this for a substrate. 1" leonardite, a thin layer of gravel from an established tank on top of the leonadite. 2-3" of eco complete for top layer.



              • #52
                Try 1/2" or less of leonardite
                It's a bit like peat.

                  Non co2 setup questions

                  I'm getting ready to set up my 20 gallon non co2 tank. I think any system of growing plants that rewards laziness is worth a try.

                  The light is a cheapo 2 bulb fixture with 30 watts of light with white gloss reflective material. I could not find any reflectors that fit this size fixture. Does anyone know where I might find reflectors to fit a 24" fixture ? Is there a simple DIY method for someone who isn't too handy that might work ? Since these lights are not very efficient could I add one more bulb for 45 watts which would normally be considered high for a non co2 tank this size ?

                  Also, I am planning to put in a small piece of wood which I anticipate will cause some discoloration. Since water changes will be infrequent, how can I remove the discoloration ? I am concerned activated carbon will remove trace elements. Is Purigen an option ?

                    These ideas are fine.
                    Mylar is what I used a few times and it was fine, I changed it after it got old and limey.

                      hi tom,

                      i would like to start up a 2.5 nano, non-co2 tank, with primarily dwarf hairgrass, anubias and java fern on driftwood. lighting will be a 13w cf, with a parabolic reflector. no circulation. no filtration. no water changes. very little ferts, weekly or every other week. tap water is moderately soft, kh and gh 3 - 4. bioload will be fairly light, a trio of endlers, couple of ghost shrimp, maybe an otto.

                      i plan on using turface pro league, capped with lapis lustre sand to make planting easier and to help keep the slope from flattening. how much peat should i use? and how deep should the entire substrate be?

                      any other suggestions? thanks.

                        I think you'll have a rough time with this one.

                        Try adding a filter.

                        Trade the ghost for Amano shrimp.
                        A small bag of Onyx sand or ADA AS would be better.
                        Soil and sand will do better than the option you wanted.

                        The rest is fine.

                          thanks for the quick reply, tom.

                          as for it being a challenge, im up for it.

                          we are unable to get amano or cherry red shrimp, in Hawaii; in fact, i think there is a ban on the importation of all invertebrates, which i wholeheartedly agree with.

                          we've got a real problem with introduced species taking over and displacing native species. we've got established colonies of big plecos, convict and johanni cichlids, to name a few. we had an salvinia infestation in one of our lakes that required a multi-million dollar clean up effort. ok. off my soapbox.

                          onyx (and florite) are too expensive locally ($45+) and i've yet to see any ada products in lfs here.

                          i'll just use my turface and hope for the best. i'll also eschew a filter cuz i don't have one small enough, and i want to assemble this tank with stuff i already have.

                            Here is the filter I use for my 2 gallon nano tank, Azoo Palm Filter, it is inexpensive, works great and isn't bad looking.


                            • #59

                              i don't give my money to a company that charges double the shipping rates to Hawaii (and Alaska) customers.

                              i'll check other online vendors. btw, how far into the tank does that filter jut? thanks.

                                I have an extra Azoo sitting here, 5$ and actual shipping is fine with me.
                                Darn near new.

                                You are going to have issues, more than need be and a 5-8$ filter can easily solve 90% of them, up for a challange and being hard headed are two different things

                                Believe me, I've done that route myself and speak from a vast array of experiences.

                                I have had 6-8 nanos in this range for about 3 years now.
