Default ZeoSpur2 for old browned softies

Hi. I have 3 year old zoanthids and other soft corals that are browned. I think this is due to the fact that at the beginning (3 years ago), I was a beginner and had high nutrients, bad lights and overall, no dosing, etc.

Now that I have learned a bit and have a pretty decent tank, with low nutrients, good lighting, I would like to "fix" the browned corals.

I read with interest about ZeoSpur2 and I think it is work a try. My main tank is a 20 gallon long tank with 10 gallon sump. It has the following overall parameters: KH 8.1 dKH (above 9 starts to affect Montipora, Birds nest and other SPS), PO4 0.07, NO3 1.0. I do vinegar dosing. PO4 and NO3 were at zero, which brought up some imbalance, causing brown "dusty" dinos on the sandbed. I'm in the process of stabilizing nutrients to "almost zero" but not zero.

Can you give me feedback about ZeoSpur2? Perhaps using it conservatively, 1/3 or 1/2 the recommended dose and see what happens? Your feedback is appreciated.

Also, I would like to know if other Zeovit products may have the same zoox controlling properties of ZeoSpur2 but maybe they are better suited for my tank? I'm not into the full zeovit line. I'm currently only trying Pohl's Xtra Special, which now I think that probably Pohl's Xtra (not special) was better suited for my corals (many browned -- not light colored).

Thanks in advance.

Hi rescure

The coals should get back their natural color if light and nutrient concentrations are adequate, also the element addition is not to high. The ZeoVit products except ZeoSpur2 does not contain elements which directly control the zoox density, its all about low nutrients, adequate light, healthy biology and the addition of several elements in the correct quantity.

I have never used ZeoSpur2 for soft corals so I am not sure if they will react to the product which works well for SPS corals. The product should also not be used to lighten up the tissue of corals which have dark tissue, it is more a fine tuning process for corals which have lighter tissue already showing good growth.

I would not expect anything negative if you use the product as recommended which meant starting with a lower quantity increasing it step by step with a dosing break of the additions of 2 weeks.

Alex, how often do you use zeospur? Is there a problem using it when po4/no3 are bit elevated?

I have usually dosed it every 10 – 14 days depending to the corals tissue coloration just if all corals where healthy. The effect to lighten the tissue with higher nutrient concentrations is low or just not there. I have never used it like some kind of a treatment to lighten the tissue of brown or darker corals just some kind of a minimal lighting effect when the corals where looking good already.
