Is the SiO2 particularly soluble in water?
Tested my tap water for SiO2 and it's off the scale as is the tank so it does appear to be from the water and even a 50/50 tap and RO isn't enough to reduce it.
If it is the one that contains an <"iron compound">? It will remove the orthophosphate (PO4---) ions from the water column as well. Whether that effects plant growth will depend on what happens in the substrate, silicon isn't essential for plant growth, but phosphorus is a macro-nutrient.JBL silicate remover
I don't actually know. I've come upon phosphate stripping with iron III chloride as part of my day job.If it absorbs PO4 can I not just up my dosing or does it remove instantly?
So it looks like it is PO4--- ion first.The apparent adsorption constants indicated that the affinity of the anions for iron hydroxide sites decreased in the following order arsenate > phosphate> arsenite> silicate >bicarbonate.
I couldn't find out, but I assume it does. Whether it suppresses Diatom growth would be another question, this one <"Influence of Ceratophyllum demersum L. on phytoplankton structure in a shallow eutrophic lake"> says it does.So, does that mean that Hornwort can absorb orthosilicic acid to construct its skeleton?
<"Silica uptake in aquatic and wetland macrophytes: a strategic choice between silica, lignin and cellulose?"> Looked at a range of wetland plants and Ceratophyllum demersum was the highest accumulator of silica, even more than for aquatic grasses.Additionally, Ceratophyllum demersum was found to inhibit diatom development, which is probably connected with the secretion of allelopathic substances by this plant. The aim of the current study was to analyze the influence of Ceratophyllum demersum L. on the structure of phytoplankton in a shallow, eutrophic lake.
Which I think is suggesting that silicon travels from submerged vegetation to diatoms in the phytoplankton.Benthic vegetation at the land-water interface is recognized as a filter for silica fluxes,
which represents an important but under-investigated subject. This paper aims to analyze stocks and fluxes of biogenic (BSi) and dissolved (DSi) silica in relation to nitrogen (N) and phosphorus (P) in the littoral zone of a deep lake. Specifically, we evaluated how different primary producers can influence BSi retention and DSi release. The study was performed in three different benthic communities: submerged aquatic vegetation (SAV) and microphytobenthos (MPB), both occurring in soft bottom sediments, and epilithic macro- and microalgae (EA) on rocky substrates. The main result was that SAV and MPB were a DSi source and a N and P sink with the DSi efflux from SAV nearly three times as much as in MPB patches.
I will need to check whether I have a picture in photobucket. Someone gave it to me for $20. I had to take a picture with my phone just to count them. After I had given away close to 200, I counted about 600. So maybe it was even more. I still have shrimp from the same colony.an army of 500 cherry shrimps
