    I am considering to move from dsb to np pellets, can somebody with experience please assist to what monthly cost would approximately be? My DT is 290l and sump is about 65l, my system is medium stocked with fish and i have some softies and lps. At the moment my filtration is reef octopus xp1000 cone skimmer, dsb is 470mm by 310mm and 110mm deep and caulerpa on dsb.

    Why do you want to change? I'm running np and it's done nothing for my tank. You replace pellets every 3-6 months.

    Well, going the np pellet route seems to be the way to go lately, would like to give it a go, I also think my dsb is a bit small for my system (DT is 140cm by 45 cm wide) and is not really working properly.

    Hi Konrad

    From a cost point of view bio pellets are very affordable I am currently running Vertex bio pellets and they took about 10 weeks to start working.

    You can expect it to take around 6 month before they are running at there full potential.

    I am running a reef octopus br70 np pellet reactor on my 4ft system and it's working perfect. No problems with ammonia, nitrite or nitrate whatsoever. It work for me better than the dsb and the good thing is it takes about 1/4 of the space the dsb takes. Pellets is not that expensive to buy and you can (depends on what type of pellets you buy) replace it between 6-12 months. Not actually replace but just add because as the pellets tumble they get smaller and eventually dissapear so you need to replace the lost pellets.

    Why not run both, if you already have a DSB why remove it? I would leave the DSB and just add the NP Pellet reactor. Rather have your eggs in two nests..

    NP Pellets are expensive to start up, but the running cost and maintenance are low. Almost like a solar geiser.

    Once started up the pellets takes about 8 - 12 weeks to kick in and from there you just top-up the used pellets.

    I recon on your system you looking at spending plus minus R2100 on a decent NP Pellet system with reactor, pellets and a pump.

    Thanks for the advice, if you run dsb and np-reactor in what order must it be in the sump (skimmer, np-reactor, dsb and return pump)? Will my skimmer be big enough to handle the np-reactor?

    The order is correct. Just make sure that the NP outlet is as close as possibple to the skimmer's intake.

    We recommend that you use a good quality skimmer rated at least 30% more than your water total for NP Pellets.

    Bio pellet reactor must be placed close to your skimmer inlet

    Should cost around R1700 for your size tank

    Lastly you may need to look at upgrading your skimmer in the future.
