Dinoflagellates!!!!!!

I haven't studied the reaction, so I don't know about the order. I do suggest you put fresh GFO in before lauching a lime water assault.

 

I'll change the GFO, how do I go about dosing that lime water from KW ?

 

Mix Kalkwasser in some FW, let it settle and out take a portion of the mixture (the clear fluid) and add it to your top off water. Your pH is going to be the lowest early in the am so that is when I would top off, but make sure you measure pH prior to addition of the KW and after to avoid significant swings, that will give you an idea of how much and how often to add it. Go slow and do not expect results immediately, give it some time.

You could also do a slow drip if you have a dosing pump.

 

I don't have a dosing pump I can order one. But I have an aqua dose drip container. Will this work?

 

Yup, I have used the exact same product.

 

I see that they claim to remove silicate. But then explain to me this: How is it possible to have a diatom outbreak white using GFO (that is changed on a regular basis)? It doesn't really matter regardless. Diatoms are a very mild problem, and will disappear over a few weeks without treatment.

Diatoms may be coming back because there is still silicate in the water. I would do the blackout either way, to be on the safe side.

 

GFO isn't proprietary stuff. It's well understood and removes silicates. The reason there remain silicates in the water is related to the chemistry of the solution and a big bore as a subject in this thread. Suffice it to say it takes a while to reach equilibrium on diatoms.

What's the drip rate for Kalkwasser ?

 

How are things going?

 

This stuff came back with a vengeance I really believe its Dino's I'm on my first day of the black out
