  1. Most straw is wheat so you would need to ask for it
  2. Plant to the right of the rock on the left is Shinnersia rivularis. It has not been submersed for very long.
  3. I don't think your Vallisneria is gigantea (it is not legal) it would be americana or spiralis would it not? V. gigantea is about 20mm or more accross the leaf and can be many metres long.
  4. The reason I think it is that is because the leaves are longer than zosteraefolia and have the characteristic "curl down". I only know of one place down here that grows it and it is not common but I could be wrong--- good luck finding out.
  5. I bought a set of 4 of different grades right down to very fine. Works a treat for bbs and for grading daphnia. I can't recall if it was from someone on this site or from Trademe but I am very happy with them.
  6. They also have a bisexual flower so many types of swords will set viable seeds from flowers grown emersed.
  7. Have a look at Eichhornia azurea on the plant geek site (it is the submersed form and the emersed is totaly different)
  8. Shinnersia is sold as Mexican or American Oak leaf
  9. vallisneria is the ribbon plant at the back, I meant the plant to the right of the rock on the left. Alternanthera roseafolia is slow growing and takes a while to convert from emersed growth but goes a very bright red on top and bottom of the leaf in time. At least you didn't buy A. rubra which is sold as beetroot and just rots. Nice tank
  10. Your client could be like the rest of us playing poker-- you have to pay to look. I hate to think how much I have spent over the years finding these things out. Tell them to buy some and try-- then let us all know.
  11. Looks good before and after. The alternanthera should go a nice red colour now it is getting more light. Is that Shinnersia on the left? looks good.
  12. Indian Star grass is Hygrophila polysperma. zosteraefolia means star leaf. The plant may be Eichhornia azurea grown submersed. I used to have it years ago, a permitted first cousin of water hyacinth (Eichhornia crassipes) needs strong light and has a blue flower. At least I think it is permitted as I used to sell it to the shops 30 years ago.
  13. Glosso is a native so will be OK, I am pretty sure there is a native eleocharis also but it is pretty tall-- grows on the west coast South Island.
  14. I know a guy who grows all three in an unheated glasshouse in Christchurch and they all all die off in the winter. They probably will not grow but might survive the winter in Auckland. Some plants will die off in winter but come away again from the roots in spring. Polysperma will if emersed but I don't know about submersed as it may rot. There are a lot of these plants sold by nurseries down here which would be realy struggling for most of the year. The easy answer would be that they are tropical plants---take the risk if you want.
  15. I don't know scientically but I would suspect daphnia would be about equivalent to adult brine shrimp which would make newly hatched nuplii better than both because they have the adition of the unused yolk sac. I feed small daphnia to larger fry as well as brine shrimp nuplii and microworm-- that way it is hard to go wrong.
  16. Once the mechanism gets wet they tend to rust and they jam on and cook.
  17. Someone was growing yabbie at one stage till the powers changed their mind and knocked them all off.
  18. If they are mosquito fish they are ilegal and not very good at getting rid of mosquito larvae. I think the turtles would be better at that.
  19. UV sanitizers are not specific. They kill everything that is vulnerable. (good and bad) Your tank is a living thing and if you kill off part of it you upset the natural balance. Everything that is killed contains protein and protein contains phosphate that can be released in the water. The only time I have used UV is when I was using seawater to keep cold water marines and removing it from the sea upsets the balance and can cause a bloom of microorganisms. I would only use it to control algae when growing madigascar lace (dream on)
  20. One is "free swimming" so will go through the sanitizer and the other is anchored so will not. It may reduce the reproduction of the anchored algae by killing spores but it is more than likely that the anchored algae will grow by cell division than by sending free floating spores.
  21. It will kill free floating algae (which are like photosynthesizing bacteria) but it will do nothing to kill algae that is not in the water.
  22. They are planaria (flatworms) they are on the glass and move along like a slug. Tubifex would be in the media anchored at one end and the other waving in the water.
