  1. Impeller axle broke in my old Accela pump (the original which comes in JBJ 28G Biocube) during the cleaning process. This is plastic 2.5" rod. If you have one that you don't need or have any ideas for replacement for this part please LMK.

    Thanks

  2. Siphon out the cyanobacter carefully with the upper layer of substrate attached to it. Check water parameters especially PO4 and NO3. Do not overfeed and most importantly increase the water movement in the substrate proximity. Get the skimmer running. Be aggressive or it will reappear soon.

  3. Common sense tells me that the coloration depends on more factors than just light. I am pretty sure the water flow is important as well as alkalinity, Mg concentration et cetera. The problem is to find the optimal conditions for each species. Corals (photosynthetic) need the dinoflagellates, however too many cause the color to become brownish, too little results in bleaching and coral death.

    Thanks for the links.

  4. Mlew I have a 29 biocube with DIY LED lights (CW and RB). I also had a panorama strip W/B in addition. This panorama strip recently died (they dont last longer than year) so I bought some 3W cre LEDs and installed them on the panorama strip. 2 violet, 1 red and 1 green. The idea was to mix some other colors and bring up the red and green. The results is the red is an overkill and so is the green. This is just too much for the nano cube. This is obviously my subjective perception.

  5. I was wondering how much pH swings in your tank. I will start with my data.

    1. What is the difference between day max versus night minimum?. - 0.2pH (8.10 - 8.30)

    2. What would you consider a safe range? -?

    3. Also please indicate if you have refugium with light and what is the light cycle. - refugium light opposite cycle to DT

    4. Any alkalinity, calcium dosing. - B-Ionic calcium and alkalinity 1ml of each every 2-3 days

    5. Capacity of the tank + refugium. - 40G

    Thanks for your input.
