Random Tip #22 - Plants
Unless it is very large grained, sand should not be used as a substrate if you have live rooted plants. Sand can compact on the plant’s roots and kill them. This can later result in stench-producing anerobic pockets in the sand. - T. Fells Add Your Tip

ANNOUNCEMENTS:

We would like to specially thank everyone who assisted with our Spring Auction and all of you who attended to make our event a great success!

May General Meeting:
Program: “An Introduction to Planted Tanks” - Travis Simonson
‘I will cover the basics of planted tanks from lighting, substrate types, and aquarium sizes to plant species, fish selection, and aquascaping. I hope to cover all of the basics of planted tanks and give your members a good idea of what can be accomplished with them.

I have been keeping aquariums most of my life and have been involved with planted tanks for about four years. I am active in the hobby and am a moderator on the AquariumAdvice.com aquarium forum as well as assistant manager at AquamartOnline in Lakewood, CO.’

ABOUT CAS:

Our objective is to promote and share information about the hobby of ornamental fish-keeping. We are a ‘general’ aquarium club that covers every aspect of the freshwater and marine aquarium hobby. This includes all fish, invertebrates, and plants kept in either tanks or ponds. The CAS was established in 1947 and incorporated under Colorado law as a non profit organization on November 6, 1962.
