Hi been distracted and forgot to add my voice to this! I have a MM system with a small skimmer. Params are pretty good considering I feed the tank. I think I'd like a bigger MM/DSB sump, but that isn't going to happen without an upgrade! :)

OK mangroves - yes I have two in the weir of my tank. They get light from the MH light and actinics and seem to be doing well.

I come from a FW planted tank background into marines. My FW tanks are run using Walstad style set ups, basically an unskimmed Berlin system, but plants do the job of the LR. The plants that work best are those "stemmed plants" that grow fast and use up nutrients and can then be harvested.

Mangroves are cool, but grow way too slowly to have enough impact on the nitrates IMO. If you could grow a lot of them, or a big one, that would be better, but you do need actual growth. Mine don't do much - a leaf ever now and then. What works are fast growing algaes and xenia. I think that salt water tolerant reeds would work brilliantly, if you could grow them hydroponically, but this is strictly hypothetical - reed beds are used to process waste water in a lot of countries and produce very clean water.

I am currently trying (in a very non-scientific way) the plant Samphire (aka glasswort) in my sump. It is a UK plant, but can tolerate high temps. It grows in tidal muds, so will grow under sea water!

I've tried growing it planted into the substrate and underwater but it seem that it tasted good and was eaten by something!

It is a human food plant and tastes something like asparagus but salty - the other reason for me trying to grow it!

I have some growing floating on the surface now and it is doing OK but nothing special. It really needs to be planted in soil and be exposed to the air for best results as it can access atmospheric CO2. Apparently though the best samphire grows where it is covered by the sea at high tide, so in my "upgrade" I am planning a tidal tank for mangroves, samphire and anything else that would like that sort of environment.

Would love to try sea grasses in a system like that! :) Just need to build an extension first to fit it all in! :) ;)

I wouldnt eat the samphire mate as it would be grown in conditions not fit for human consumption - i.e. an artificial reef - products in artificial sea water mixes may not be too good for humans - I dunno but this may be the case

Hi Cranners. The tank is not being dosed with meds nor will it be. I'm not sure what could be bad in a tank as the plant will filter out anything it doesn't need. The problems with some plants like say watercress is that they collect heavy metals, which might be a problem, but only if you eat it too often! :D

ps could it be worse than eating veg out of a city garden?! :D

Samphire sounds like an intersting idea. I too moved from freshwater systems using plants to filter the water.

The biggest version I did was a pond I set up 16 years ago for terrapins in my parents conservatory, as they are such messy animals and my mum didn't want to do too many water changes. i set up a small 4ft river/water fall full of hygrophylia. Worked very well as both a mechanical and biological filter. All you had to do was trim the emerse growth shoots every few weeks.:D

Wow slight headache on that then lol

An update on my system. I have some new corals - new green bubble, acans, and an unnamed aussie coral (2 frags). I have seen my algae grow quite a lot recently and my parameters seem to be fine. I am going to test them tomorrow to see how the Ca and Mg is doing.

I am planning to set up an auto top system on the tank to help with the evaporation replacement as I am currently doing this manually.

Next thing to sort out is the balling method using a GHL stand alone dosing pump.

Ooops I managed to kill the samphire.

Samphire planted in the sump was eaten by pods!!!

Interesting thing was that both plants and cuttings died pretty much at the same time and this coincided with the central heating coming on during the cold snap. Nothing else seemed to fit. I'm keeping the dead plants handy in case they sprout again. If anyone has ever kept cryptocoryne you know that even when all looks bleak some plants can seen to come back from the dead!

I really don't have a clue, but temps are stable and we don't have a hermetically sealed house - this one being about 100yrs old with "original features" like draughts! Will try again next year.

Be interested to hear if any one else succeeds.
