Effects Of Too Much Phytoplankton

So just plant fertilizer from home depot would work to feed,

Any particular brands that you woul recomend or what should i look for when i buy some

 

Yeah a liquid pot plant fertiliser like baby bio from a home depot store will work.

 

Is that an absolute must have or cna they survive solely on light?

 

Not even remotely. Like anything else, they need nutrients to survive.

 

Right, but what do they feed on in the ocean then? is there something smaller than phyto that they eat?

 

There are a lot of nutrients in the ocean, they normally end up in deeper water and then go through cycles in the temperate seas. This is why temperate zones are greener than tropical waters. In the tropics there are less nutrients and this causes an oligotrophic environment. This is one of the reasons why algae live in symbiosis with coral as the coral can provide instant nutrients from its waste and a safe home. There is actually a large amount of organic bacteria in tropic waters. This makes up the picoplankton or bacterioplankton and is fed on by a lot of organisms such as pods and sessile filter feeders like tube worms and sponges.

There is a smaller amount of phytoplankton in tropical seas compared with the temperate zone. Reefs form in shallow waters usually around areas such as islands that have rain water run off which provide a stream of nutrients and can fuel small localised phyto blooms feeding organisms that have settled there.

 

Alright thanks for telling me that, so i guess the bag of baby bio is essential to keep the cultures growing

 

Yeah any plant pot NPK (nitrogen phosphate potassium) liquid fertiliser will work.

 

Well bad news, today i saw that both of the cultures were foaming which is a sign there crashing,

How will i know when there completely gone? One is a very light green and the other is slighty green brown but thats may be do to the fat i put more phyto in that one
