    I have a 1.2m tropical tank that I would like to convert into a fowlr tank. I will clean the tank with vinegar during the conversion preparation.

    Is it possible that I can run it without a sump? Only a canister filter (regular clean)? What's the easiest/ simplest way?

    What about lighting? Do I need to upgrade current lighting to T5's?

    What should SG be?

    What are the tests to be performed? Nitrate? Phos?

    What should the RO water reading be on TDS? 0?

    Should temp fluctuations be limited? Do I need a chiller?

    How important is flow in fowlr compared to a reef tank?

    I already have a RSM250 with coral, etc and would like to start a fowlr.

    I would not recommend a new reefer to start out without a sump and proper filtration system.


    Yes, at least upgrade to 4 or 6 54w T5 bulbs over the 1.2m

    1.026

    Yes, as a start NO2, NO3, PO4. Then after the cycle monitor the other other parameters.

    TDS should be 0 or just a tad above before hanging filters!
    Your temperature should stay at 26. A chiller is only needed if your temperature spike beyond 30.

    Flow is still very important

    Good luck with your adventure!

    The basic principles used on your 250 should suffice if it is doing fine

    Guys,

    I need urgent advice.

    I started the fowlr tank with the following equipment:

    Canister filter (ceramic rings, carbon and orca), Seio (M1100) and Sun sun (single) pumps, 4 x T5's, air stone. I added an internal skimmer. Note: no SUMP.;)

    I always get nitrite spikes. Why is this? Is it possible that there isn't sufficient flow for Orca?

    I do monthly 20% water changes. I use the following products: Special blend, Nite out, Nopox.

    I lost some LS in the past few months due to these spikes, although I do not have a heavy bio load.

    I need some of the 'gurus' to advice.... @Dallas, @RiaanP, @nemosjanitor, @Viper, @carlos, @bryan and any other person with fowlr experience. It's really becoming frustrating to lose LS especially if I don't know the cause and what to do to mitigate:)

    how much live rock do you have?

    I suspect that you do not get enough water turnover into your filtration. So old food etc drops down and gets trap inside the display tank.

    What clean up crew do you have? Any hermits?

    In a marine environment nitrite is not generally dangerous to fishes. If, however, you can measure nitrite it does mean nitrification processess are not functioning optimally which means your also likely to get ammonia..

    "None of the thirteen marine fish species for which I could find nitrite toxicity data had LC50 values below 100 ppm, and half had LC50 values of 1,000 - 3,000 ppm or more"

    I have approx 15kg LR.

    Will a second canister assist?

    No clean up crew at this point. Should I consider clean up crew? If yes, what should I get? Snails? Hermits?

    do you siphon the gravel when you do water changes?
    The problem I think is a build up of crap in the subtrate. Does it release a green pea soup cloud when disturbed?

    Thanks for your advice.

    The only problem is that I tested on Sunday evening and Ammo was <0.025 and Nitrite 0, Nitrate 25.

    What should I do? I really need to sort out my tank.

    Is there anything that I can dose to remedy the situation?

    I do siphon the grave (gravel cleaner).

    It's more brownish and not green.....

    How much are you feeding your fish?could be due to over feeding as well,if you want to use something to kill nitrates use micro bacteria works very well and it makes your water clear as well,Just my 2 cents
    All the luck

    Normally a pattern of chronic mortality (ones and twos here and there, now wipe-out) has its roots in poor water quality. As mentioned,

    1.) If you insist on having substrate :)tt2:), make sure its cleaned regularly, CUC ect. Also sorry to ask but your rocks were placed on the glass bottom with substrate distributed around the rock (good) or rocks placed on top of substrate (bad) .
    2.) Reduce stocking/feeding rate.
    3.) Good flow (at least 8-10 times IMO) helps with oxygen in the aquarium which is needed for all respiration including the nitrification bacteria. It also helps keep fish waste in suspension so it doesn't settle to the substrate and is actually delivered to the filters.
    4.) Did you have a skimmer for your FOWLR? If not even a modest hang on back (HOB) model will produce a noticeable difference in fowlr.

    I'm feeding twice per day. I don't over feed, just sufficient for fish to eat within 3 to 5 minutes.

    Micro bacteria?

    1. Some rocks are on glass with substrate around it and others on substrate. I will change this - all rock will be on the glass.

    2. I feed for fish to eat within 3 to 5 minutes.

    3. I will consider to increase flow. I do have a Seio M1100 and single Sun Sun.

    4. I bought a skimmer on Sunday.

    Do you think I should replace the Orca in the Canister with another product? Not even sure what I can replace it with. I currently have carbon, ceramic rings and Orca in the Canister.

    2. ) Cool, feeding once a day? Consider doing so (or even every second day) while your correcting water quality

    3.) Sharp

    4.) Skimmer still brand new and will probably take a for day or two to settle. You will see an improvement soon.

    I have never used Orca but if you only have 25ppm Nitrate then I suspect its been doing a good job. The experience on the forum generally suggests it works better in a simple bag (search bomb method) but realistically you need a sump for that. Personally in FOWLR NO3 not the greatest water quality concern. I reckon a good pre-filter (poly filter or sponge which will trap solids and can be rinsed regularly) fresh carbon, and ceramic rings should cope with a reasonably stocked fowlr with skimmer and live rock,

    Canister filter is ok for a flower tank softies and lps. How big (size) is your canister filter. Like Istio said use filter material or sponge in your filter help a lot to trap the solids.

    It's a Dophin, 1150l/h.

    I have a 4 ft tank. I'm in the process if getting a second canister filter.
