Be Gentle With Me I'm A Virgin Poster! didnt think a piece of paper from richard branson could make such a good tank!
Nitrates and phosphates do not cause algae and don`t let anyone tell you otherwise.
I fertilise my three planted tanks with N and P and have no algae related issues. If I wanted algae, all I have to do is make any one of the plant nutrients become deficient, stunt the growth of my plants and voila! Algae needs a germination trigger, usually light and/or Ammonia or a failing plant biomass.
hey gaz whereabouts are you in sussex?
Eh? In all due defference to your experience this is a pretty well understood biological principal and not some flight of fancy.Nitrates and phosphates do not cause algae and don`t let anyone tell you otherwise.
I didn't want to go into amateur scientist mode at risk of sounding like a bit of a nobber, but another reason for using sandy substrates is that it introduces a good level of silicates. This tends to result in a diatom growth rather than an algae growth. Diatoms being easier to clean, more pleasant to look at and readily munched up by lovely fish like otocinclus. You take a look at a tank using sandy substrate and you'll tend to notice diatoms being prevalent. You look at those aquarist gravel type arrangements and they tend to be plagued by various forms of green algae. Depending on other stuff. Maybe it's a preference thing but I'll take the diatoms every time. I suppose you could add silicates somehow but I wouldn't know how to go about that.
Using a UV unit in a planted tank is in my view a fundamentally bad idea. It tends to oxidize all sorts of handy plant nutrients also. I don't think there's any bloom where it's not healthier to bring under control by hitting the root causes or waiting for things to sort themselves out.
